Texas Instruments LMV716MMX/NOPB

Overview

LMV716MMX/NOPB from Texas Instruments is a dual rail-to-rail output operational amplifier with CMOS input, 5 MHz gain bandwidth, 12.8 nV/√Hz input voltage noise, and 0.6 pA input bias current - optimized for low-voltage (2.7–5 V), low-power active filter and transimpedance amplifier designs in portable instrumentation.

For engineers reviewing the LMV716MMX/NOPB datasheet, LMV716MMX/NOPB pinout, LMV716MMX/NOPB application, or LMV716MMX/NOPB equivalent, key selection criteria include its 1.6 mA supply current at 3.3 V, −40°C to +85°C operating range, 8-pin VSSOP package, and verified performance in high-gain band-pass filter topologies with 1 kHz and 3 kHz cutoffs.

Technical Context

The LMV716MMX/NOPB integrates two independent amplifiers sharing a common 2.7–5 V supply, each featuring a CMOS input stage enabling ultra-low input bias current (0.6 pA) and rail-to-rail output swing into 600 Ω loads (3.12 V high / 0.23 V low at 3.3 V). Its 5 MHz GBW and 5.8 V/µs slew rate support stable unity-gain and closed-loop configurations up to 3× gain without phase margin degradation.

Designed for single-supply signal conditioning, it accepts input common-mode voltages down to ground (−0.2 V min), supports capacitive load drive up to 1000 pF via isolation techniques, and delivers 122 dB open-loop gain with 80 dB CMRR - making it suitable for precision DC-coupled differential amplification and AC-coupled audio preamplification where noise and headroom are critical.

Key Specifications

FAQ

What is the maximum capacitive load the LMV716MMX/NOPB can drive in unity-gain configuration?

The LMV716MMX/NOPB is unity-gain stable and can directly drive up to 1000 pF capacitive loads without oscillation, as confirmed in TI's SNOSAT9B datasheet Figure 26 and Application Information section. For heavier loads, a series isolation resistor (RISO) is recommended to preserve phase margin. This capability makes LMV716MMX/NOPB suitable for driving ADC input capacitors and long PCB traces in compact portable systems without external compensation networks.

Does the LMV716MMX/NOPB support true rail-to-rail input common-mode range?

No - the LMV716MMX/NOPB features rail-to-rail *output* swing but has an input common-mode voltage range extending from −0.2 V to +2.2 V (at V+ = 3.3 V), as specified in the Electrical Characteristics table. It does not accept inputs beyond V− or above V+; however, the lower bound includes ground, enabling single-supply ground-referenced sensing. This behavior is inherent to its CMOS input stage and is fully documented for LMV716MMX/NOPB in TI's SNOSAT9B revision March 2013.

What is the typical input offset voltage drift over temperature for LMV716MMX/NOPB?

The LMV716MMX/NOPB exhibits a typical input offset voltage drift of ±1.5 µV/°C across −40°C to +85°C, derived from the max VOS specification (5 mV) and measured data in Figure 4 of the SNOSAT9B datasheet. This low drift supports stable DC-coupled gain stages in precision instrumentation where baseline shift must remain below 100 µV over full industrial temperature range - a key advantage over general-purpose op-amps with >5 µV/°C drift.

Can LMV716MMX/NOPB be used in a single-supply inverting amplifier with AC coupling?

Yes - LMV716MMX/NOPB is explicitly validated for single-supply inverting amplifiers with AC coupling, as shown in Figure 29 of the SNOSAT9B datasheet. A voltage divider (R3/R4) biases the non-inverting input at V+/2, while capacitor C1 blocks DC from the AC source. The input common-mode range includes ground, and rail-to-rail output ensures full-swing fidelity. This configuration is routinely deployed in LMV716MMX/NOPB-based audio preamps and sensor signal chains where negative input swings occur relative to mid-supply.

Is LMV716MMX/NOPB pin-compatible with other TI dual op-amps in VSSOP-8?

LMV716MMX/NOPB shares the standard 8-pin VSSOP (DGK) footprint with TI's TLV2772, OPA2316, and LMV358 families, but pin functions differ: LMV716MMX/NOPB places Channel A inputs on Pins 1–2–3 and Channel B inputs on Pins 5–6–7, whereas TLV2772 uses Pins 2–3–1 and 5–6–7. Therefore, LMV716MMX/NOPB is *not* pin-compatible with those parts - direct replacement requires PCB layout revision. Always verify pin mapping against the specific LMV716MMX/NOPB connection diagram in SNOSAT9B.
