Product details
Overview
LMV721M7X/NOPB from Texas Instruments is a single-channel, rail-to-rail output, low-noise (9 nV/√Hz at 1 kHz), low-voltage (2.2 V to 5.5 V) operational amplifier in SC70-5 package. It delivers 10 MHz unity-gain bandwidth, 5.25 V/µs slew rate at 5 V, and 930 µA quiescent current at 2.2 V - optimized for battery-powered microphone preamplifiers and portable signal conditioning.
For engineers reviewing the LMV721M7X/NOPB datasheet, LMV721M7X/NOPB pinout, LMV721M7X/NOPB application, or LMV721M7X/NOPB equivalent, key selection criteria include its guaranteed 2.2 V operation, input common-mode range extending to ground, 600 Ω load rail-to-rail swing (120 mV from rails), and SC70 footprint for space-constrained PCBs.
Technical Context
The LMV721M7X/NOPB uses a bipolar input stage with BiCMOS process, enabling low input bias current (260 nA typical) and low voltage noise while maintaining rail-to-rail output drive into 600 Ω. Its phase margin is 72° at 5 V, ensuring stable unity-gain operation even with capacitive loads up to 4700 pF.
Designed for single-supply systems, it supports input common-mode voltage down to −0.3 V (with clamping recommended) and up to 4.1 V at 5 V supply. Output swing is specified at both 2.2 V and 5 V, with guaranteed performance across −40°C to +85°C junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.2 V to 5.5 V - enables full functionality across depleted battery voltages in portable devices. |
| Unity-Gain Bandwidth | 10 MHz - supports audio-band amplification (20 Hz–20 kHz) with >500× gain margin at 20 kHz. |
| Slew Rate | 5.25 V/µs at 5 V - allows clean 1 VPP output at 100 kHz without distortion. |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz - critical for low-level signal amplification such as electret microphone preamps. |
| Quiescent Current | 0.93 mA at 2.2 V - extends battery life in always-on sensor front-ends and wearable electronics. |
| Rail-to-Rail Output | Swings within 120 mV of either rail at 600 Ω load - maximizes dynamic range in 3 V systems. |
| Input Common-Mode Range | Includes ground (−0.3 V to 4.1 V at 5 V) - permits direct DC-coupled sensing near 0 V in single-supply configs. |
Pinout & Package
LMV721M7X/NOPB is packaged in SC70-5 (DCK0005A), measuring 2.0 mm × 2.0 mm × 1.0 mm with 0.65 mm pin pitch. The package is RoHS-compliant, lead-finished with Sn, and rated MSL Level-1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (−) | High-impedance node accepting differential signal; requires matched impedance to non-inverting input for bias current cancellation. |
| 2 | Non-Inverting Input (+) | High-impedance node; common-mode range includes ground, enabling single-supply DC coupling. |
| 3 | Ground (GND) | Reference for single-supply operation; must be low-impedance return path to minimize noise coupling. |
| 4 | Output (OUT) | Rail-to-rail capable; drives 600 Ω loads to within 120 mV of supply rails at 2.2 V. |
| 5 | Supply Voltage (V+) | Accepts 2.2–5.5 V; internal regulation ensures stable biasing across voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise amplification | 9 nV/√Hz input voltage noise at 1 kHz enables high-fidelity audio preamplification without added noise floor. |
| Rail-to-rail output swing | Delivers full 2.065 V output swing at 2.2 V supply into 600 Ω - preserves SNR in low-voltage systems. |
| Guaranteed 2.2 V operation | Specified performance down to 2.2 V supply ensures reliable function across entire Li-ion battery discharge curve (3.0 V → 2.5 V). |
| Bipolar input stage | 260 nA typical input bias current allows precision DC-coupled designs with <10 kΩ source impedances. |
| Capacitive load tolerance | Stable with up to 4700 pF capacitive load in unity-gain configuration - eliminates need for external isolation in many sensor interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-noise, low-voltage op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV271IDBVR | Lower quiescent current (170 µA), but lower GBW (3 MHz) and higher noise (29 nV/√Hz). | Preferred for ultra-low-power sensor wake-up circuits where bandwidth <100 kHz suffices. | Choose TLV271IDBVR only when power budget is stricter than noise/bandwidth requirements. |
| OPA333AIDBVR | Zero-drift architecture (0.02 µV/°C offset drift), but higher supply current (17 µA) and lower GBW (350 kHz). | Required for precision DC-coupled instrumentation where offset stability dominates AC performance. | Choose OPA333AIDBVR when microvolt-level offset drift over temperature is critical, not bandwidth or noise. |
Compared with TLV271IDBVR and OPA333AIDBVR, LMV721M7X/NOPB uniquely balances 10 MHz bandwidth, 9 nV/√Hz noise, and sub-1 mA quiescent current - making it optimal for audio and wideband sensor front-ends where all three parameters matter simultaneously.

FAQ
What is the maximum capacitive load the LMV721M7X/NOPB can drive without oscillation?
The LMV721M7X/NOPB is stable driving up to 4700 pF in unity-gain configuration, as verified in TI's datasheet Figure 23. This eliminates need for external isolation resistors in many sensor and ADC driver applications. For loads exceeding 4700 pF, TI recommends adding a series isolation resistor (e.g., 100 Ω) between the LMV721M7X/NOPB output and the capacitive load to restore phase margin.
Does the LMV721M7X/NOPB support true single-supply operation with input signals near ground?
Yes - the LMV721M7X/NOPB features an input common-mode voltage range that includes ground (−0.3 V to 4.1 V at 5 V supply), enabling direct DC-coupled sensing of signals referenced to 0 V. However, TI advises clamping input voltages below −0.3 V using external diodes to prevent damage to the bipolar input stage.
What is the thermal resistance (θJA) of the LMV721M7X/NOPB in its SC70-5 package?
The LMV721M7X/NOPB in SC70-5 (DCK) package has a thermal resistance θJA of 440°C/W, as specified in the Operating Ratings table of the datasheet. This value assumes standard JEDEC 2-layer board conditions; actual θJA improves significantly with PCB copper pour and thermal vias under the exposed pad (though SC70 lacks an exposed pad).
How does the LMV721M7X/NOPB perform at 2.2 V supply compared to 5 V?
At 2.2 V, the LMV721M7X/NOPB maintains 10 MHz GBW and 4.9 V/µs slew rate, with output swing reduced to 2.065 V (min) into 600 Ω. Quiescent current drops to 0.93 mA, and input offset voltage remains ≤3.5 mV. TI explicitly guarantees full specification compliance at both 2.2 V and 5 V - confirming robust low-voltage operation.
Is the LMV721M7X/NOPB pin-compatible with other SC70-5 op amps like the TLV271 or MCP6001?
No - LMV721M7X/NOPB uses standard SC70-5 pinout (IN−, IN+, GND, OUT, V+), but TLV271IDBVR and MCP6001-I/OT use different pin assignments (e.g., V+ on pin 5 vs. pin 1). Always verify pin mapping per manufacturer datasheet; physical compatibility does not imply functional or pinout compatibility.
