LPV358IDDUR Equivalent & Substitute Parts

Part Overview

The LPV358IDDUR is a general-purpose operational amplifier manufactured by Texas Instruments, featuring dual circuits in a rail-to-rail configuration. This device is classified as obsolete, with 3282 pieces currently in stock. The LPV358IDDUR is designed for low-power applications requiring minimal input bias current and low input offset voltage across a 2.7V to 5V supply range.

Due to its obsolete product status, identifying equivalent and substitute parts is necessary for design continuity, long-term availability assurance, and production planning. Active alternatives with compatible electrical and mechanical specifications are available from the same manufacturer.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LPV358IDDUR is determined by the following critical parameters:

Electrical Compatibility Criteria:

• Dual-circuit general-purpose operational amplifier configuration
• Rail-to-rail output capability
• Supply voltage range: 2.7V to 5V minimum compatibility
• Input bias current: 2 nA specification
• Input offset voltage: 1.5 mV specification
• Low-power operation: 15µA supply current per channel
• Output current capability: minimum 16 mA per channel

Mechanical Compatibility Criteria:

• Surface mount package type
• 8-pin VSSOP/TSSOP/MSOP package family
• Pin configuration compatibility

Compliance Criteria:

• ROHS3 compliance
• REACH unaffected status
• EAR99 export classification

The substitute parts identified maintain the core electrical specifications of the LPV358IDDUR while offering active product status and improved availability. Substitutes are grouped based on their adherence to these parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Closest Electrical Match):

LPV358MM/NOPB and LPV358MMX/NOPB maintain identical electrical specifications to the LPV358IDDUR, including slew rate (0.1V/µs), gain bandwidth product (152 kHz), input bias current (2 nA), and supply current (15µA per channel). Both parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating. The primary difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel) and operating temperature range (-40°C ~ 85°C versus -40°C ~ 125°C for the main part). These substitutes are suitable for applications where the reduced upper operating temperature limit is acceptable.

Secondary Substitutes (Enhanced Performance):

LMV358MM/NOPB and LMV358MMX/NOPB offer improved performance characteristics with 10x higher gain bandwidth product (1 MHz versus 152 kHz), 10x faster slew rate (1V/µs versus 0.1V/µs), and 10x higher output current capability (160 mA versus 16 mA per channel). These parts maintain the same supply voltage range minimum (2.7V) with an extended maximum (5.5V). Input bias current is higher at 15 nA, and supply current per channel increases to 210µA. Both are active products with ROHS3 compliance. The LMV358 series is suitable for applications requiring higher bandwidth and output drive capability.

Compliance and Availability:

All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Inventory levels for active substitutes exceed 15,000 pieces, ensuring long-term availability compared to the obsolete LPV358IDDUR.

Frequently Asked Questions (FAQ)

Q: Can LPV358MM/NOPB directly replace LPV358IDDUR in all applications?

A: LPV358MM/NOPB is electrically equivalent to LPV358IDDUR with identical slew rate, gain bandwidth product, input bias current, and supply current specifications. The primary consideration is the reduced operating temperature range (-40°C ~ 85°C versus -40°C ~ 125°C). Applications operating above 85°C require evaluation. Package dimensions differ slightly (8-TSSOP/8-MSOP at 0.118" width versus 8-VFSOP at 0.091" width), requiring PCB layout verification.

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

A: The LMV358 series provides 10x improvement in gain bandwidth product (1 MHz versus 152 kHz), 10x faster slew rate (1V/µs versus 0.1V/µs), and 10x higher output current per channel (160 mA versus 16 mA). Supply current per channel increases from 15µA to 210µA. Input bias current increases from 2 nA to 15 nA. The LMV358 series is suitable for higher-speed applications requiring greater output drive capability.

Q: Are package dimensions compatible between LPV358IDDUR and substitute parts?

A: LPV358IDDUR uses 8-VFSOP packaging (0.091" width), while LPV358MM/NOPB, LPV358MMX/NOPB, LMV358MM/NOPB, and LMV358MMX/NOPB use 8-TSSOP or 8-MSOP packaging (0.118" width). Both are 8-pin surface mount packages with identical pin configurations, but PCB footprint dimensions differ. Layout modifications are required for substitution.

Q: What is the moisture sensitivity difference between substitute parts?

A: LPV358MM/NOPB and LPV358MMX/NOPB maintain MSL 1 (Unlimited) rating, identical to LPV358IDDUR. LMV358MM/NOPB and LMV358MMX/NOPB have MSL 2 (1 Year) rating, requiring moisture control during storage and handling. MSL 2 components must be baked before reflow soldering if storage exceeds one year in non-controlled environments.

Q: Which substitute part offers the best long-term availability?

A: LMV358MM/NOPB and LMV358MMX/NOPB are recommended for long-term availability, with inventory exceeding 45,000 and 15,400 pieces respectively. Both are active products with established production lines. LPV358MM/NOPB and LPV358MMX/NOPB also maintain active status with substantial inventory (50,000 and 23,100 pieces).

Q: Can LMV358 series be used in low-power applications designed for LPV358?

A: LMV358 series increases supply current per channel from 15µA to 210µA, a 14x increase. Applications with strict power consumption budgets require circuit redesign or alternative selection. The LPV358MM/NOPB or LPV358MMX/NOPB maintain the original power profile while offering active product status.

Q: What compliance certifications apply to all substitute parts?

A: All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification, identical to the LPV358IDDUR. No additional compliance modifications are required for substitution.
