Engineering Selection Recommendations

Primary Substitutes (Texas Instruments LMV712 Series):

LMV712MM/NOPB and LMV712MMX/NOPB are direct functional equivalents to the LMV712IDGST. Both parts are active products from Texas Instruments, sharing identical electrical specifications and package designations. The distinction between these two substitutes lies in packaging format: LMV712MM/NOPB is supplied in Tape & Reel (TR) configuration, while LMV712MMX/NOPB is supplied in Cut Tape (CT) & Digi-Reel® format. Both maintain ROHS3 compliance and MSL Level 1 rating. Selection between these two should be based on procurement and assembly process requirements.

Secondary Substitute (Rohm Semiconductor LMR982FVM-TR):

The LMR982FVM-TR is a cross-manufacturer substitute from Rohm Semiconductor. This device maintains compatibility across primary substitution criteria: dual general purpose amplifier circuits, rail-to-rail output, surface mount configuration, and identical operating temperature range. However, the LMR982FVM-TR exhibits reduced performance in secondary parameters: slew rate of 0.35 V/µs (versus 5 V/µs), gain bandwidth product of 1.4 MHz (versus 5 MHz), input bias current of 5 nA (versus 5.5 pA), and input offset voltage of 1 mV (versus 400 µV). The LMR982FVM-TR is suitable for applications where lower bandwidth and slower signal processing are acceptable, and where the reduced supply current requirement (140 µA versus 1.17 mA) provides system-level advantages. The supply voltage range is narrower (1.8V to 5V versus 2.7V to 5.5V).

Compliance and Availability:

All three substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with modern manufacturing and environmental standards. LMV712MM/NOPB and LMV712MMX/NOPB are active products with confirmed inventory availability. LMR982FVM-TR is also active with available stock.

Frequently Asked Questions (FAQ)

Q: Can LMV712MM/NOPB directly replace LMV712IDGST in existing designs?

A: Yes. LMV712MM/NOPB is a direct functional equivalent with identical electrical specifications, operating temperature range, and package designation. The primary difference is packaging format (Tape & Reel versus the original device packaging). No circuit modifications are required.

Q: What is the difference between LMV712MM/NOPB and LMV712MMX/NOPB?

A: Both parts are electrically identical with matching specifications. The difference is in supplier packaging: LMV712MM/NOPB is supplied in Tape & Reel (TR) format, while LMV712MMX/NOPB is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on assembly line requirements and procurement preferences.

Q: Can LMR982FVM-TR be used as a substitute for LMV712IDGST?

A: LMR982FVM-TR is a functional substitute for applications where reduced bandwidth and slower slew rate are acceptable. The LMR982FVM-TR has a slew rate of 0.35 V/µs and gain bandwidth product of 1.4 MHz, compared to 5 V/µs and 5 MHz for the LMV712IDGST. Applications requiring high-speed signal processing or fast transient response should use LMV712MM/NOPB or LMV712MMX/NOPB instead.

Q: Are there package compatibility concerns when substituting these parts?

A: LMV712MM/NOPB and LMV712MMX/NOPB use identical package designations (10-TFSOP, 10-MSOP, 10-VSSOP) to the LMV712IDGST and are directly compatible with existing PCB layouts. LMR982FVM-TR uses 10-VFSOP and 10-MSOP packages; while the 10-MSOP footprint is compatible, the 10-VFSOP variant has slightly different dimensions (0.110" versus 0.118" width). Verify PCB layout compatibility before selecting LMR982FVM-TR.

Q: What is the supply voltage compatibility range for each substitute?

A: LMV712MM/NOPB and LMV712MMX/NOPB operate across 2.7V to 5.5V, matching the original LMV712IDGST. LMR982FVM-TR operates across 1.8V to 5V, which is narrower at the minimum but covers the same maximum. Designs operating below 1.8V cannot use LMR982FVM-TR.

Q: Do all substitutes maintain the same output current capability?

A: LMV712MM/NOPB and LMV712MMX/NOPB provide 50 mA per channel output current, identical to LMV712IDGST. LMR982FVM-TR provides 90 mA per channel, which is superior. Applications requiring exactly 50 mA output current can use any substitute; applications requiring higher output current benefit from LMR982FVM-TR.

Q: Are there input bias current differences between substitutes?

A: LMV712MM/NOPB and LMV712MMX/NOPB maintain 5.5 pA input bias current, identical to LMV712IDGST. LMR982FVM-TR has 5 nA input bias current, which is significantly higher. High-impedance input applications should use LMV712MM/NOPB or LMV712MMX/NOPB to minimize input bias current effects.

Q: What is the input offset voltage specification for each part?

A: LMV712MM/NOPB and LMV712MMX/NOPB specify 400 µV input offset voltage, matching LMV712IDGST. LMR982FVM-TR specifies 1 mV input offset voltage. Precision analog applications requiring low offset voltage should use LMV712MM/NOPB or LMV712MMX/NOPB.

Q: Are all substitutes RoHS3 compliant?

A: Yes. LMV712MM/NOPB, LMV712MMX/NOPB, and LMR982FVM-TR are all ROHS3 compliant with MSL Level 1 rating, ensuring compatibility with modern manufacturing processes and environmental regulations.
