LPV358IDR Equivalent & Substitute Parts

Part Overview

The LPV358IDR is a general-purpose operational amplifier manufactured by Texas Instruments, featuring dual circuits in an 8-SOIC surface-mount package with rail-to-rail output capability. This device is classified as obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and procurement continuity. The LPV358IDR operates across a 2.7 V to 5 V supply range with low input bias current (2 nA) and minimal input offset voltage (1.5 mV), making it suitable for low-power analog signal processing applications.

Substitute Part Grouping Explanation

Substitution of the LPV358IDR is determined by the following critical parameters: amplifier type (general purpose), number of circuits (2), output type (rail-to-rail), package type (8-SOIC with 0.154" width), supply voltage range compatibility (minimum 2.7 V, maximum 5 V), and operating temperature range (-40°C to 125°C). Substitute parts must maintain electrical compatibility within these boundaries while accommodating the obsolete status of the original device.

Substitute parts are grouped into two categories:

Category 1: Direct LPV358 Series Variants (Highest Compatibility) These parts share the identical base product number (LPV358) and maintain the same electrical characteristics, slew rate (0.1 V/µs), gain bandwidth product (152–237 kHz range), and supply specifications. Differences exist only in packaging format (Tube, Tape & Reel) and product status (Active). These variants are pin-compatible and functionally equivalent.

Category 2: Alternative General-Purpose Amplifiers (Functional Equivalents) These parts provide general-purpose dual-circuit amplification in 8-SOIC packaging with rail-to-rail output, but introduce variations in slew rate, gain bandwidth product, supply current, and output current. Substitution requires verification that application-specific performance requirements remain satisfied within the altered electrical parameters.

Category 3: Specialized CMOS Amplifiers (Limited Substitution) These parts offer ultra-low input bias current (pA range) and reduced supply current, suitable for applications requiring minimal power consumption. However, they introduce significant variations in slew rate and gain bandwidth product, requiring application-level assessment.

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

LPV358M/NOPB and LPV358MX/NOPB are direct variants of the LPV358 base product with active product status. These parts maintain identical electrical specifications to the LPV358IDR (slew rate 0.1 V/µs, gain bandwidth product 152 kHz, input bias current 2 nA, input offset voltage 1.5 mV) and are pin-compatible in 8-SOIC packaging. The primary difference is operating temperature range (-40°C to 85°C versus -40°C to 125°C for the original). Selection between M/NOPB (Tube packaging) and MX/NOPB (Tape & Reel packaging) depends on procurement and assembly requirements. Both are ROHS3 compliant with MSL 1 rating.

Secondary Substitutes (Functional Equivalents with Enhanced Performance):

LMV358M/NOPB and LMV358MX/NOPB offer improved performance characteristics within the LMV® series. These parts provide 10× higher slew rate (1 V/µs), 4.2× higher gain bandwidth product (1 MHz), and 2.2× higher output current per channel (160 mA). Supply current increases to 210 µA. Operating temperature extends to -40°C to 125°C, matching the original device. These substitutes are suitable for applications requiring faster signal processing while maintaining rail-to-rail output and 8-SOIC packaging compatibility. ROHS3 compliance and MSL 1 rating are maintained.

Alternative Substitutes (Specialized Applications):

AD8617ARZ-REEL (Analog Devices Inc., CMOS type) provides ultra-low input bias current (0.2 pA) and extended minimum supply voltage (1.8 V). Slew rate remains 0.1 V/µs, but gain bandwidth product increases to 400 kHz. This device is suitable for applications requiring minimal input current and lower supply voltage operation. Operating temperature range is -40°C to 125°C. ROHS3 compliance and MSL 1 rating apply.

MAX4077ESA+ (Analog Devices Inc./Maxim Integrated, GainAmp™ series) is classified as obsolete, similar to the LPV358IDR. This part provides comparable slew rate (0.09 V/µs) and gain bandwidth product (230 kHz) with ultra-low input bias current (1 pA). However, operating temperature is limited to -40°C to 70°C, and supply voltage maximum extends to 5.5 V. This substitute is suitable only for applications with temperature requirements not exceeding 70°C.

All recommended substitutes maintain ROHS3 compliance, MSL 1 rating, and 8-SOIC surface-mount packaging. Selection should be based on specific application requirements for slew rate, gain bandwidth product, output current, supply voltage range, and operating temperature.

Frequently Asked Questions (FAQ)

Q1: Can LPV358M/NOPB directly replace LPV358IDR in existing designs?

A: LPV358M/NOPB is pin-compatible and electrically equivalent to LPV358IDR with identical slew rate (0.1 V/µs), gain bandwidth product (152 kHz), input bias current (2 nA), and input offset voltage (1.5 mV). The primary difference is operating temperature range: LPV358M/NOPB operates -40°C to 85°C, while LPV358IDR operates -40°C to 125°C. Direct replacement is suitable for applications operating within the -40°C to 85°C range. For applications requiring operation above 85°C, LMV358M/NOPB or LMV358MX/NOPB are recommended alternatives.

Q2: What is the difference between LPV358M/NOPB and LPV358MX/NOPB?

A: Both parts are electrically identical with the same specifications. The difference is packaging format: LPV358M/NOPB is supplied in Tube packaging, while LPV358MX/NOPB is supplied in Tape & Reel (TR) format. Selection depends on procurement volume and assembly line requirements. Tape & Reel format is typically preferred for high-volume automated assembly.

Q3: Why would I choose LMV358MX/NOPB over LPV358MX/NOPB?

A: LMV358MX/NOPB provides enhanced performance: 10× higher slew rate (1 V/µs versus 0.1 V/µs), 6.6× higher gain bandwidth product (1 MHz versus 152 kHz), and 10× higher output current per channel (160 mA versus 16 mA). Supply current increases from 15 µA to 210 µA. Selection of LMV358MX/NOPB is appropriate for applications requiring faster signal processing, higher output drive capability, or wider bandwidth. Both maintain 8-SOIC packaging and -40°C to 125°C operating temperature range.

Q4: Is AD8617ARZ-REEL suitable for low-power applications?

A: AD8617ARZ-REEL is suitable for applications requiring ultra-low input bias current (0.2 pA, approximately 10,000× lower than LPV358IDR). However, supply current is 38 µA, which is 2.5× higher than LPV358IDR (15 µA). This device is optimized for applications where input bias current minimization is critical, such as high-impedance sensor interfaces. For general low-power applications, LPV358 variants remain more efficient.

Q5: Can I use MAX4077ESA+ as a substitute?

A: MAX4077ESA+ is electrically similar with comparable slew rate (0.09 V/µs) and gain bandwidth product (230 kHz). However, this part is classified as obsolete, similar to LPV358IDR. More importantly, operating temperature is limited to -40°C to 70°C, which is significantly narrower than LPV358IDR (-40°C to 125°C). MAX4077ESA+ is suitable only for applications with maximum operating temperature not exceeding 70°C. For broader temperature range requirements, LMV358 or LPV358 variants are recommended.

Q6: Are all substitute parts ROHS3 compliant?

A: Yes, all recommended substitute parts (LPV358M/NOPB, LPV358MX/NOPB, LMV358M/NOPB, LMV358MX/NOPB, AD8617ARZ-REEL, and MAX4077ESA+) are ROHS3 compliant with Moisture Sensitivity Level (MSL) 1 (Unlimited). This ensures compatibility with modern manufacturing processes and environmental regulations.

Q7: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and does not require special moisture-control storage or handling procedures. This simplifies inventory management and reduces procurement complexity compared to higher MSL ratings that require controlled humidity storage and time-limited floor life after package opening.

Q8: Are there package size differences between substitute parts?

A: All recommended substitutes use 8-SOIC surface-mount packaging with 0.154" (3.90mm) width, matching the LPV358IDR package footprint. This ensures PCB layout compatibility without redesign. Note that some Rohm Semiconductor alternatives (BU7266F-E2, BU7266SF-E2, BU7486F-E2, LMR932F-GE2) use 8-SOP packaging with 0.173" (4.40mm) width, which is not footprint-compatible and requires PCB redesign.
