LMP7701MAX/NOPB Equivalent & Substitute Parts

Part Overview

The LMP7701MAX/NOPB is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This rail-to-rail output amplifier is designed for applications requiring low input bias current and precision signal conditioning. The part is currently in active production status with 2700 units in stock. Substitute parts are identified based on matching functional category, package type, and electrical parameter compatibility within the 8-SOIC form factor and rail-to-rail output specification.

Substitute Part Grouping Explanation

Substitution eligibility for the LMP7701MAX/NOPB is determined by the following criteria:

Primary Matching Criteria:

Amplifier Type: General Purpose
Number of Circuits: 1
Output Type: Rail-to-Rail
Package / Case: 8-SOIC (0.154", 3.90mm Width)
Mounting Type: Surface Mount
Operating Temperature Range: -40°C to 125°C
Supply Voltage Compatibility: Minimum 2.7 V, Maximum 12 V

Secondary Compliance Criteria:

RoHS3 Compliance
Moisture Sensitivity Level 1 (Unlimited)
Active Product Status

All identified substitute parts meet these core requirements. Variations in slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current per channel are documented in the parameter comparison table and do not disqualify substitution eligibility within the general-purpose amplifier category.

Engineering Selection Recommendations

All identified substitute parts—OP196GSZ, OP196GSZ-REEL7, TS921IDT, and TS951IDT—maintain active product status and full RoHS3 compliance with MSL 1 rating, ensuring long-term availability and environmental regulatory alignment with the LMP7701MAX/NOPB.

Packaging Considerations:

LMP7701MAX/NOPB: Standard packaging (Tube)
OP196GSZ: Tube packaging
OP196GSZ-REEL7: Cut Tape & Digi-Reel® packaging
TS921IDT: Tape & Reel (TR) packaging
TS951IDT: Cut Tape & Digi-Reel® packaging

Selection between substitute parts should account for procurement volume requirements and assembly line compatibility with available tape-and-reel or tube handling equipment.

Supply Voltage Compatibility Note: OP196GSZ and OP196GSZ-REEL7 specify a minimum supply voltage of 3 V, compared to 2.7 V for the LMP7701MAX/NOPB and STMicroelectronics alternatives. Applications operating below 3 V require TS921IDT or TS951IDT.

Frequently Asked Questions (FAQ)

Q: Can OP196GSZ be used as a direct replacement for LMP7701MAX/NOPB?

A: OP196GSZ meets the core substitution criteria: general-purpose amplifier, 1 circuit, rail-to-rail output, 8-SOIC package, surface mount, -40°C to 125°C operating range, and RoHS3 compliance. However, the minimum supply voltage is 3 V versus 2.7 V for the LMP7701MAX/NOPB. Applications requiring operation below 3 V must use TS921IDT or TS951IDT.

Q: What is the difference between OP196GSZ and OP196GSZ-REEL7?

A: Both parts are electrically identical Analog Devices OP196 amplifiers with identical electrical specifications. The difference is packaging format: OP196GSZ is supplied in Tube packaging, while OP196GSZ-REEL7 is supplied in Cut Tape & Digi-Reel® format. Selection depends on assembly equipment compatibility and procurement volume.

Q: Why do TS921IDT and TS951IDT have different electrical characteristics?

A: TS921IDT and TS951IDT are distinct STMicroelectronics part numbers with different base products (TS921 versus TS951). Both meet the 8-SOIC package and rail-to-rail output requirements, but differ in slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, and output current specifications. Application-specific performance requirements determine which is appropriate.

Q: Are all substitute parts REACH compliant?

A: All identified substitute parts carry REACH Unaffected status, matching the LMP7701MAX/NOPB compliance profile.

Q: Can I use OP196GSZ in a circuit designed for 2.7 V supply operation?

A: No. OP196GSZ specifies a minimum supply voltage of 3 V. For 2.7 V operation, use LMP7701MAX/NOPB, TS921IDT, or TS951IDT, all of which support 2.7 V minimum supply voltage.

Q: What is the inventory status of substitute parts?

A: Current inventory levels are: OP196GSZ (5005 units), OP196GSZ-REEL7 (3108 units), TS921IDT (2915 units), TS951IDT (3317 units). Availability should be confirmed with the supplier for production requirements.
