Texas Instruments LMV716MM

Overview

LMV716MM from Texas Instruments is a dual, rail-to-rail output operational amplifier with CMOS input stage, designed for low-voltage portable systems. It delivers 5 MHz gain bandwidth, 12.8 nV/√Hz input voltage noise, 0.6 pA input bias current, and operates from 2.7 V to 5 V supply - enabling high-precision active filters and transimpedance amplifiers in battery-powered audio and sensor signal conditioning.

For engineers reviewing the LMV716MM datasheet, LMV716MM pinout, LMV716MM application, or LMV716MM equivalent, key selection criteria include its 1.6 mA supply current per amplifier, −40°C to +85°C industrial temperature range, 8-pin VSSOP package, and verified performance in single-supply high-pass/low-pass bandpass filter topologies with passband gains up to 50.

Technical Context

The LMV716MM integrates two independent amplifiers sharing a common 2.7–5 V supply, each featuring a CMOS input stage that enables ultra-low input bias current (0.6 pA) and rail-to-rail output swing into 600 Ω loads. Its 5 MHz GBW and 5.8 V/µs slew rate support stable unity-gain and closed-loop configurations up to 3 kHz corner frequencies in active filter designs.

Input common-mode range extends to ground, supporting true single-supply operation with mid-supply biasing. The device exhibits 80 dB CMRR and 82 dB PSRR at 3.3 V, with open-loop gain of 122 dB - ensuring accurate DC-coupled differential sensing and low-distortion AC signal amplification in compact PCB layouts near sensors.

Key Specifications

Pinout & Package

LMV716MM is housed in an 8-pin VSSOP (DGK) package with 0.5 mm pitch, 3.0 mm × 3.0 mm body size, and exposed thermal pad - optimized for space-constrained PCBs near analog sensors. Pin 1 is marked with a dot; device orientation follows TI standard top-view labeling.

FAQ

What is the maximum capacitive load the LMV716MM can drive without oscillation?

The LMV716MM is unity-gain stable and can directly drive ≥1000 pF capacitive loads without external compensation. This capability is verified in TI's datasheet Figure 26 and enables simplified anti-aliasing filter integration. For loads exceeding 1000 pF, a series isolation resistor (e.g., 10–100 Ω) between the LMV716MM output and the capacitor restores phase margin while preserving DC accuracy when paired with feed-forward compensation.

Does the LMV716MM support true single-supply operation with input signals referenced to ground?

Yes, the LMV716MM supports true single-supply operation: its input common-mode voltage range includes ground (−0.2 V to +2.2 V at V+ = 3.3 V), and its rail-to-rail output swings within 78 mV of V+ and 120 mV of GND into 600 Ω. This allows direct interfacing with ground-referenced sensors and eliminates the need for level-shifting circuitry in 3.3 V systems.

What is the typical input offset voltage of the LMV716MM, and how does it affect precision DC measurements?

The LMV716MM has a typical input offset voltage of 1.6 mV (max 5 mV over temperature), which introduces ≤1.6 mV error in unity-gain configurations. In high-gain transimpedance stages (e.g., 10 MΩ feedback), this translates to ≤16 nA equivalent input error current. For sub-nanoamp precision, system-level calibration or chopper-stabilized alternatives should be considered - but the LMV716MM remains suitable for most industrial sensor front-ends.

Can the LMV716MM be used in a three-op-amp instrumentation amplifier configuration?

Yes, the LMV716MM is explicitly recommended in TI's application notes for three-op-amp instrumentation amplifiers. Its 0.6 pA input bias current minimizes resistor mismatch errors, and its 80 dB CMRR ensures effective common-mode rejection. Example designs in the LMV716MM datasheet (Figure 30) achieve ≥80 dB CMRR using 1% resistors and dual LMV716MM sections for input buffers plus a third for the difference stage.

Is the LMV716MM pin-compatible with other TI dual op-amps in the VSSOP-8 package?

No, the LMV716MM is not pin-compatible with generic VSSOP-8 dual op-amps such as the TLV2462 or OPA2340. Its pinout (OUT A, IN− A, IN+ A, V−, IN+ B, IN− B, OUT B, V+) is specific to the LMV716 family. Substitution requires schematic and layout revision; always verify pin mapping against the official TI LMV716MM datasheet before redesign.
