LPV358MX Equivalent & Substitute Parts Reference

Part Overview

The LPV358MX 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 Last Time Buy, indicating limited future availability. The LPV358MX operates across a 2.7V to 5V 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.

Due to its Last Time Buy status, identifying equivalent and substitute parts is necessary for design continuity and long-term component sourcing strategy. Substitute parts must maintain compatibility across electrical performance parameters, mechanical packaging, and operational temperature ranges while considering alternative manufacturers and product statuses.

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

LPV358MX/NOPB is the primary direct equivalent, offering identical electrical specifications with Active product status. This part maintains the same 8-SOIC package, supply voltage range (2.7V to 5V), and operating temperature range (-40°C to 85°C). Both parts are RoHS3 compliant with MSL Level 1 rating. Selection of LPV358MX/NOPB is recommended when inventory of the original LPV358MX becomes constrained.

For Enhanced Performance Applications:

LMV358QDR (Texas Instruments, Active status) provides superior electrical performance with 10× higher slew rate (1V/µs vs. 0.1V/µs), 6.6× higher gain-bandwidth product (1 MHz vs. 152 kHz), and extended operating temperature range (-40°C to 125°C). The 8-SOIC package and supply voltage compatibility (2.7V to 5.5V) ensure mechanical and electrical interchangeability. This part is suitable for applications requiring faster signal processing or wider temperature operation.

LMV358LIDT (STMicroelectronics, Active status) offers comparable performance enhancement with 1.3 MHz bandwidth and 0.7V/µs slew rate, with extended temperature range to 125°C. This part maintains 8-SOIC packaging and RoHS3 compliance.

For Ultra-Low Power Applications:

BU7266F-E2 or BU7266SF-E2 (Rohm Semiconductor, Active status) provide ultra-low supply current (0.7 µA vs. 15 µA per channel), suitable for battery-powered or energy-harvesting applications. However, these parts feature significantly reduced bandwidth (4 kHz) and slew rate (0.0024V/µs), limiting use to low-frequency signal conditioning. Package is 8-SOP (0.173", 4.40mm width), requiring PCB layout verification.

For High-Speed Applications:

BU7486F-E2 (Rohm Semiconductor, Active status) delivers 10V/µs slew rate and 10 MHz bandwidth, suitable for high-frequency signal processing. Minimum supply voltage is 3V (vs. 2.7V for LPV358MX), requiring verification in low-voltage designs. Operating temperature extends to 105°C.

For Maximum Output Current:

LMR932F-GE2 (Rohm Semiconductor, Active status) provides 90 mA output current per channel (vs. 16 mA), enabling direct driving of higher-impedance loads. Supply voltage range (1.8V to 5V) includes lower minimum voltage. Slew rate (0.35V/µs) and bandwidth (1.4 MHz) are intermediate between LPV358MX and LMV358 variants.

Compliance Verification:

All recommended substitutes maintain RoHS3 compliance and MSL Level 1 rating. REACH status is unaffected for all parts. ECCN classification remains EAR99 across all alternatives.

Frequently Asked Questions (FAQ)

Q1: Can LPV358MX/NOPB be used as a direct drop-in replacement for LPV358MX?

Yes. LPV358MX/NOPB is electrically and mechanically identical to LPV358MX, with the same 8-SOIC package, supply voltage range (2.7V to 5V), operating temperature (-40°C to 85°C), and all electrical specifications. The primary difference is product status: LPV358MX/NOPB is Active, while LPV358MX is Last Time Buy. No circuit modifications are required.

Q2: What are the key differences between LPV358MX and LMV358QDR?

LMV358QDR offers enhanced performance: 10× faster slew rate (1V/µs vs. 0.1V/µs), 6.6× higher bandwidth (1 MHz vs. 152 kHz), higher output current (40 mA vs. 16 mA), and extended temperature range (-40°C to 125°C vs. -40°C to 85°C). Both use 8-SOIC packaging and are compatible with 2.7V to 5V supplies. LMV358QDR is suitable for faster signal processing but draws higher supply current (210 µA vs. 15 µA per channel).

Q3: Are Rohm Semiconductor alternatives (BU7266, BU7486, LMR932) pin-compatible with LPV358MX?

All Rohm alternatives use 8-SOP packaging (0.173", 4.40mm width) versus LPV358MX's 8-SOIC (0.154", 3.90mm width). While both are 8-pin surface-mount packages with identical pinout, the physical dimensions differ. PCB footprint verification is required before substitution. Pin functionality remains compatible.

Q4: Which substitute part is best for battery-powered applications?

BU7266F-E2 or BU7266SF-E2 are optimal for battery applications, consuming only 0.7 µA supply current (21× lower than LPV358MX). However, these parts are limited to 4 kHz bandwidth and 0.0024V/µs slew rate, suitable only for low-frequency signal conditioning (audio, sensor interfaces, DC amplification). For higher-frequency battery applications, LMR932F-GE2 offers a compromise with 140 µA supply current and 1.4 MHz bandwidth.

Q5: Can LMV358IDR (UMW manufacturer) replace LPV358MX?

LMV358IDR is not recommended as a direct replacement. While it offers superior bandwidth (1 MHz) and lower input bias current (10 pA), it uses 14-SOP packaging (vs. 8-SOIC), has a narrower operating temperature range (-25°C to 85°C, missing the -40°C lower limit), and is classified as Voltage Feedback amplifier rather than General Purpose. PCB redesign would be required.

Q6: What is the impact of switching from LPV358MX to LMV358LIDT?

LMV358LIDT (STMicroelectronics) provides improved performance with 1.3 MHz bandwidth and 0.7V/µs slew rate, extended temperature range to 125°C, and Active product status. Supply current increases from 15 µA to 130 µA per channel. The 8-SOIC package and supply voltage range (2.7V to 5.5V) remain compatible. No PCB modifications are required; circuit performance will improve for signal-processing applications.

Q7: Are all substitute parts RoHS3 compliant?

Yes. All recommended substitute parts (LPV358MX/NOPB, LMV358 series, BU7266 series, BU7486F-E2, LMR932F-GE2, LMV358LIDT) are RoHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating. REACH status is unaffected for all parts. ECCN classification is EAR99 across all alternatives.

Q8: Which substitute offers the best balance of performance and power consumption?

LMV358LIDT provides optimal balance: 1.3 MHz bandwidth and 0.7V/µs slew rate (8.6× and 7× improvements over LPV358MX) with moderate supply current increase (130 µA vs. 15 µA per channel). Extended temperature range (-40°C to 125°C) and Active product status ensure long-term availability. 8-SOIC packaging requires no PCB changes.

Q9: What is the minimum supply voltage for each substitute part?

LPV358MX and most Texas Instruments alternatives (LPV358MX/NOPB, LMV358ID, LMV358IDRG4, LMV358QDR) require minimum 2.7V. LMV358LIDT (STMicroelectronics) also requires 2.7V minimum. LMR932F-GE2 operates at 1.8V minimum. BU7266 and BU7486 series require 1.8V and 3V minimum respectively. Verify minimum supply voltage compatibility in your application before substitution.

Q10: Can LPV358MX be used in applications requiring -40°C to 125°C temperature range?

No. LPV358MX is rated only to 85°C maximum. For extended temperature range (-40°C to 125°C), use LMV358ID, LMV358IDRG4, LMV358QDR, or LMV358LIDT. These parts maintain 8-SOIC packaging and 2.7V to 5.5V supply compatibility while extending maximum operating temperature to 125°C.
