Texas Instruments LMV722ID

Overview

LMV722ID from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage, low-noise, and low-power applications. It operates from 2.2 V to 5.5 V, delivers 10 MHz unity-gain bandwidth, 5.25 V/µs slew rate at 5 V, and 9 nV/√Hz input voltage noise at 1 kHz - enabling high-fidelity signal conditioning in battery-powered portable electronics.

For engineers reviewing the LMV722ID datasheet, LMV722ID pinout, LMV722ID application, or LMV722ID equivalent, key selection criteria include its rail-to-rail output swing into 600 Ω (120 mV from rails at 2.2 V), input common-mode range extending to ground, and guaranteed 3.5 mV max input offset voltage over –40°C to 105°C.

Technical Context

The LMV722ID implements a CMOS input stage with complementary bipolar output drivers, supporting stable operation with capacitive loads up to 21.2 nF at 2.2 V supply. Its phase margin remains ≥67.4° across 2.2 V–5.5 V supplies, ensuring robust closed-loop stability in unity-gain buffer and active filter configurations.

It features matched dual-channel architecture with independent inputs and outputs, no internal cross-coupling, and identical electrical specifications per channel - allowing use in differential amplifiers, instrumentation front-ends, and stereo audio preamplifiers without channel-to-channel mismatch concerns.

FAQ

What is the maximum capacitive load the LMV722ID can drive stably?

The LMV722ID maintains phase margin ≥67.4° and stable unity-gain operation with capacitive loads up to 21.2 nF at 2.2 V supply, as verified in TI's SLOS470C datasheet Figure 22–27. This capability eliminates need for isolation resistors when driving ADC input capacitance, LCD bias networks, or long PCB traces - provided a 0.1 µF ceramic decoupling capacitor is placed within 5 mm of Pin 8 (VCC+).

Does the LMV722ID support true single-supply operation with input signals at ground potential?

Yes, the LMV722ID features an input common-mode voltage range that includes ground (–0.3 V to VCC+ – 1.3 V at 2.2 V supply), allowing direct connection of 0 V-referenced sources like electret microphones or current-sense shunts without external level-shifting circuitry. This is confirmed in the Electrical Characteristics table on page 3 of the SLOS470C datasheet.

What is the guaranteed input offset voltage specification for LMV722ID over temperature?

The LMV722ID has a maximum input offset voltage of 3.5 mV across the full operating junction temperature range of –40°C to 105°C, as specified in the Electrical Characteristics table (page 3, SLOS470C). This value applies to both amplifiers independently and is tested per channel during production screening.

Can the LMV722ID replace the LMV722IDR in existing designs without layout changes?

Yes, the LMV722ID and LMV722IDR share identical SOIC (D) package dimensions, pinout, thermal characteristics, and electrical specifications - differing only in packaging format (tube vs. tape-and-reel) and reel marking. No PCB modifications are required when substituting LMV722ID for LMV722IDR in prototype or low-volume builds.

What is the minimum supply voltage at which LMV722ID maintains 10 MHz gain-bandwidth product?

The LMV722ID sustains a typical gain-bandwidth product of 10 MHz across its entire recommended supply range of 2.2 V to 5.5 V, as documented in the Electrical Characteristics table (page 3, SLOS470C). Performance remains stable down to 2.2 V, enabling use in deeply discharged battery scenarios where other 10-MHz op-amps typically degrade below 2.7 V.
