LMV796MF Equivalent & Substitute Parts

Part Overview

The LMV796MF is a general-purpose operational amplifier manufactured by Texas Instruments, housed in a SOT-23-5 surface mount package. This device features rail-to-rail output capability with a 1-circuit configuration, designed for low-power applications requiring single-supply operation across 1.8V to 5.5V supply ranges. The LMV796MF is classified as obsolete, necessitating identification of active equivalent and substitute components for new designs and production continuity. Substitute parts must maintain functional compatibility through matching electrical specifications and mechanical packaging standards.

• Output Type: Rail-to-Rail
• Operating Temperature Range: -40°C to 125°C
• Supply Voltage Range: Minimum 1.8V to 5.5V maximum

Mechanical Compatibility Criteria:

• Package / Case: SC-74A, SOT-753 (SOT-23-5 footprint)
• Mounting Type: Surface Mount

Performance Parameters (Secondary Consideration):

• Slew Rate: 11.5 V/µs (reference value)

Substitute parts are grouped into two categories:

Category 1 - Direct Equivalents: Parts maintaining identical or superior electrical performance with matching SOT-23-5 packaging and active product status.

Parameter Comparison

Engineering Selection Recommendations

Tier 1 - Direct Replacement (Highest Compatibility):

LMV796MF/NOPB is the direct equivalent of the obsolete LMV796MF. This part maintains identical electrical specifications, operates across the same supply voltage range (1.8V to 5.5V), and is housed in the same SOT-23-5 package. The primary distinction is product status (Active vs. Obsolete) and RoHS compliance (ROHS3 Compliant vs. Non-compliant). This part is suitable for direct substitution in existing designs without circuit modification.

Tier 2 - Primary Functional Substitutes (High Compatibility):

MCP6L91T-E/OT and MCP6L91RT-E/OT (Microchip Technology) provide functional substitution with active product status and ROHS3 compliance. These parts maintain SOT-23-5 packaging, operate across 2.4V to 6V supply range (encompassing the LMV796MF range), and support the full -40°C to 125°C temperature range. Performance variations include lower slew rate (7 V/µs vs. 11.5 V/µs) and reduced gain bandwidth product (10 MHz vs. 17 MHz), with improved input offset voltage (1 mV vs. 100 µV) and lower supply current (0.85 mA vs. 1.15 mA).

TSV991AILT and TSV991AIYLT (STMicroelectronics) offer functional substitution with active status and ROHS3 compliance. These parts feature SOT-23-5 packaging, operate across 2.5V to 5.5V supply range, and support -40°C to 125°C operation. Performance characteristics include higher slew rate (10 V/µs) and superior gain bandwidth product (20 MHz), with lower supply current (0.82 mA). TSV991AIYLT includes automotive qualification (AEC-Q100) for applications requiring automotive-grade components.

Tier 3 - Secondary Functional Substitutes (Moderate Compatibility):

MCP6291T-E/OT and MCP6291RT-E/OT (Microchip Technology) provide functional substitution with active status and ROHS3 compliance. These parts maintain SOT-23-5 packaging and -40°C to 125°C temperature range. Supply voltage range extends to 6V maximum. Performance trade-offs include lower slew rate (7 V/µs), reduced gain bandwidth product (10 MHz), and significantly reduced output current capability (25 mA vs. 60 mA).

AD8691AUJZ-REEL7 (Analog Devices Inc.) offers functional substitution with active status and ROHS3 compliance. This part uses TSOT-23-5 packaging (thin variant of SOT-23-5) and operates across 2.7V to 5.5V supply range with -40°C to 125°C temperature support. Performance characteristics include lower slew rate (5 V/µs), reduced gain bandwidth product (10 MHz), and higher output current capability (80 mA).

NCS2003ASN2T1G (onsemi) provides functional substitution with active status and ROHS3 compliance. This part uses 5-TSOP packaging (thin SOT-23-5 variant) and operates across 1.7V to 5.5V supply range. Operating temperature range is limited to -40°C to 85°C. Performance characteristics include higher slew rate (12.5 V/µs) and higher output current capability (96 mA), with lower supply current (0.3 mA).

Compliance and Regulatory Considerations:

All substitute parts listed are ROHS3 compliant and REACH unaffected, addressing regulatory requirements for new designs. The original LMV796MF is RoHS non-compliant, making substitution necessary for applications subject to RoHS directives. All parts maintain EAR99 export classification and identical HTSUS coding (8542.33.0001).

Frequently Asked Questions (FAQ)

Q1: Can LMV796MF/NOPB be used as a direct replacement for LMV796MF?

A: Yes. LMV796MF/NOPB is the direct equivalent with identical electrical specifications, package type (SOT-23-5), and operating characteristics. The primary differences are product status (Active vs. Obsolete) and RoHS compliance (ROHS3 Compliant vs. Non-compliant). No circuit modifications are required.

Q2: What are the key differences between SOT-23-5 and TSOT-23-5 packaging?

A: TSOT-23-5 is the thin variant of SOT-23-5, with reduced package height. Both maintain identical pin pitch and footprint compatibility. Parts using TSOT-23-5 (AD8691AUJZ-REEL7, NCS2003ASN2T1G) are mechanically compatible with SOT-23-5 PCB layouts. Verify PCB clearance specifications for thin package variants in high-density designs.

Q3: Which substitute part offers the closest performance match to LMV796MF?

A: LMV796MF/NOPB provides identical performance specifications. Among active substitutes, TSV991AILT and TSV991AIYLT offer the closest match with superior gain bandwidth product (20 MHz vs. 17 MHz) and comparable slew rate (10 V/µs vs. 11.5 V/µs). MCP6L91T-E/OT and MCP6L91RT-E/OT provide lower power consumption with acceptable performance trade-offs.

Q4: Are there supply voltage compatibility concerns when substituting?

A: The LMV796MF operates across 1.8V to 5.5V. Most substitutes support this range or extend it. NCS2003ASN2T1G extends the minimum to 1.7V. MCP6291 and MCP6L91 series extend maximum to 6V. Verify that substitute part supply voltage range encompasses your application requirements. No circuit modification is required if the substitute supports the original supply voltage range.

Q5: What is the impact of reduced output current capability in MCP6291 series?

A: MCP6291T-E/OT and MCP6291RT-E/OT provide 25 mA output current versus 60 mA for LMV796MF. This reduction limits load-driving capability. Applications requiring output currents exceeding 25 mA require external buffering or selection of alternatives (TSV991AILT: 35 mA, NCS2003ASN2T1G: 96 mA, AD8691AUJZ-REEL7: 80 mA).

Q6: Which substitute is recommended for automotive applications?

A: TSV991AIYLT is qualified to AEC-Q100 automotive standard and includes automotive-grade specifications. This part is suitable for automotive applications requiring qualified components. Non-automotive substitutes (TSV991AILT, MCP6L91T-E/OT, MCP6291T-E/OT) are not qualified for automotive use.

Q7: How do input offset voltage differences affect circuit design?

A: LMV796MF specifies 100 µV input offset. Substitutes vary: MCP6L91 series (1 mV), TSV991AIYLT (1.5 mV), NCS2003ASN2T1G (500 µV), AD8691AUJZ-REEL7 (400 µV), MCP6291 series (3 mV). Higher offset voltages require larger input bias current compensation or offset nulling circuits in precision applications. Verify offset voltage specifications against application accuracy requirements.

Q8: What packaging considerations apply when selecting substitutes?

A: All substitutes use SOT-23-5 or TSOT-23-5 packaging with identical pin pitch and footprint. Verify PCB layout compatibility, particularly for thin package variants (TSOT-23-5). Tape & Reel (TR) and Cut Tape (CT) packaging options affect procurement and assembly processes but do not impact electrical or mechanical compatibility.
