LPV358DDUR Equivalent & Substitute Parts

Part Overview

The LPV358DDUR is a general-purpose operational amplifier manufactured by Texas Instruments, configured as a dual-channel (2 circuit) rail-to-rail output device in an 8-VSSOP surface mount package. This part is classified as obsolete, which necessitates identification of active substitute components for new designs and production continuity. The LPV358DDUR 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 conditioning applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LPV358DDUR is determined by the following critical parameters:

Functional Equivalence Criteria:

• Dual-channel (2 circuit) general-purpose operational amplifier configuration
• Rail-to-rail output capability
• 8-pin surface mount package (VSSOP, TSSOP, or MSOP variants)
• Supply voltage range compatibility: minimum 2.7 V, maximum 5 V or higher
• Operating temperature range: -40°C to 85°C or extended to 125°C

Electrical Performance Boundaries:

• Input bias current: 2 nA (LPV358 series) or up to 15 nA (LMV358 series)
• Input offset voltage: 1.5 mV to 1.7 mV
• Slew rate: 0.1 V/µs (LPV358 series) or 1 V/µs (LMV358 series)
• Gain bandwidth product: 152 kHz to 1 MHz
• Output current per channel: 16 mA to 160 mA

Compliance Requirements:

• RoHS3 compliance
• REACH unaffected status
• EAR99 export classification

The substitute parts are grouped into two categories: LPV358 series (direct electrical equivalents with identical performance specifications) and LMV358 series (enhanced performance variants with higher bandwidth and output current capability).

Parameter Comparison

Engineering Selection Recommendations

LPV358MM/NOPB and LPV358MMX/NOPB (Direct Equivalents)

These parts maintain identical electrical performance specifications to the LPV358DDUR, including slew rate (0.1 V/µs), gain bandwidth product (152 kHz), input bias current (2 nA), and supply current (15 µA per channel). Both are active products with unlimited moisture sensitivity (MSL 1), ensuring long-term availability and storage flexibility. The primary difference between these two variants is packaging format: LPV358MM/NOPB is supplied in Cut Tape (CT) and Digi-Reel format, while LPV358MMX/NOPB is supplied in Tape & Reel (TR) format. Both are RoHS3 compliant and REACH unaffected. Selection between these two should be based on procurement and assembly requirements rather than electrical performance.

LMV358MM/NOPB and LMV358MMX/NOPB (Enhanced Performance Variants)

These parts represent an upgrade path from the LPV358DDUR, offering significantly improved performance characteristics: 10× higher slew rate (1 V/µs versus 0.1 V/µs), 6.6× higher gain bandwidth product (1 MHz versus 152 kHz), and 2.2× higher output current per channel (160 mA versus 72 mA). The LMV358 series maintains compatibility with the 2.7 V minimum supply voltage and extends the maximum supply voltage to 5.5 V. Operating temperature range extends to 125°C. Input bias current increases to 15 nA and supply current increases to 210 µA per channel. These parts are suitable for applications requiring higher bandwidth or output drive capability. Moisture sensitivity level is MSL 2 (1 Year), requiring controlled storage conditions. Both variants are active products with full RoHS3 compliance.

Product Status Consideration

The LPV358DDUR is classified as obsolete. All substitute parts listed (LPV358MM/NOPB, LPV358MMX/NOPB, LMV358MM/NOPB, LMV358MMX/NOPB) are active products with confirmed inventory availability, ensuring long-term supply continuity for new designs and production requirements.

Frequently Asked Questions (FAQ)

Q: Can LPV358MM/NOPB or LPV358MMX/NOPB be used as direct replacements for LPV358DDUR?

A: Yes. Both LPV358MM/NOPB and LPV358MMX/NOPB are electrically equivalent to the LPV358DDUR. They maintain identical slew rate (0.1 V/µs), gain bandwidth product (152 kHz), input bias current (2 nA), input offset voltage (1.5 mV), and supply current specifications. The primary differences are product status (active versus obsolete), packaging format (Cut Tape/Digi-Reel versus Tape & Reel), and package dimensions (8-TSSOP/8-MSOP at 0.118" width versus 8-VFSOP at 0.091" width). PCB layout modifications may be required due to package footprint differences.

Q: What are the key differences between LPV358 and LMV358 series?

A: The LMV358 series provides enhanced performance across multiple parameters: slew rate increases from 0.1 V/µs to 1 V/µs (10× improvement), gain bandwidth product increases from 152 kHz to 1 MHz (6.6× improvement), and output current per channel increases from 16 mA to 160 mA (10× improvement). Supply current increases from 15 µA to 210 µA per channel. Input bias current increases from 2 nA to 15 nA. Operating temperature range extends from -40°C to 125°C (versus -40°C to 85°C). Maximum supply voltage increases from 5 V to 5.5 V. These enhancements make LMV358 suitable for higher-speed applications and higher-impedance load driving.

Q: Are there package compatibility issues when substituting LPV358DDUR with LPV358MM/NOPB or LPV358MMX/NOPB?

A: Yes. The LPV358DDUR uses an 8-VFSOP package with 0.091" (2.30 mm) width, while LPV358MM/NOPB and LPV358MMX/NOPB use 8-TSSOP or 8-MSOP packages with 0.118" (3.00 mm) width. Although both are 8-pin surface mount packages with identical pin counts and functions, the physical footprints differ. PCB redesign is required to accommodate the larger package dimensions. Pin-to-pin electrical compatibility is maintained.

Q: What is the difference between LPV358MM/NOPB and LPV358MMX/NOPB?

A: Both parts are electrically identical with identical performance specifications. The difference is packaging format: LPV358MM/NOPB is supplied in Cut Tape (CT) and Digi-Reel format, while LPV358MMX/NOPB is supplied in Tape & Reel (TR) format. Selection depends on assembly equipment compatibility and procurement preferences. Both maintain MSL 1 (unlimited moisture sensitivity) and are active products.

Q: Should I use LMV358 instead of LPV358 for new designs?

A: Selection depends on application requirements. If the application requires higher bandwidth (1 MHz versus 152 kHz), faster slew rate (1 V/µs versus 0.1 V/µs), or higher output current (160 mA versus 16 mA per channel), LMV358 is the appropriate choice. If the application operates within the LPV358 performance envelope and requires minimal power consumption (15 µA versus 210 µA supply current), LPV358 is suitable. Both are active products with full compliance certifications.

Q: What is the moisture sensitivity level (MSL) difference, and does it matter?

A: LPV358 series parts have MSL 1 (unlimited shelf life without moisture control), while LMV358 series parts have MSL 2 (1-year shelf life with moisture control). MSL 1 provides greater storage flexibility and longer shelf life without requiring desiccant packaging or controlled humidity environments. MSL 2 requires adherence to moisture control procedures during storage and handling. For applications with extended inventory holding periods, LPV358 series offers logistical advantages.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (LPV358MM/NOPB, LPV358MMX/NOPB, LMV358MM/NOPB, LMV358MMX/NOPB) are RoHS3 compliant and REACH unaffected, matching the compliance status of the LPV358DDUR.
