Product details
Overview
LMV722MM from Texas Instruments is a dual, rail-to-rail output, low-noise (9 nV/√Hz), low-voltage (2.2 V to 5.5 V), and low-power (1.81 mA typical at 2.2 V) operational amplifier in an 8-pin VSSOP package. It delivers 10 MHz unity-gain bandwidth, 5.25 V/µs slew rate at 5 V, and ±0.135 V output swing headroom into 2 kΩ at 5 V - enabling high-fidelity signal conditioning in space-constrained battery-powered audio and sensor front-ends.
For engineers reviewing the LMV722MM datasheet, LMV722MM pinout, LMV722MM application, or LMV722MM equivalent, key selection criteria include its guaranteed 2.2 V operation, input common-mode range extending to ground, 3.5 mV max input offset voltage over temperature, and capacitive load tolerance up to 4700 pF in unity-gain configuration.
Technical Context
The LMV722MM uses a bipolar input stage with BiCMOS process technology, delivering low input bias current (260 nA) and low input voltage noise (9 nV/√Hz at 1 kHz). Its rail-to-rail output stage supports heavy loads (±10 mA min sourcing/sinking at 2.2 V) while maintaining phase margin ≥67.4° and gain margin −9.8 dB at 2.2 V.
Designed for single-supply systems, it features an input common-mode voltage range that includes ground (−0.3 V to 4.1 V at 5 V), enabling direct sensing of near-ground signals. The device operates across −40°C to +85°C and is qualified per JEDEC MSL Level-1 (260°C peak reflow).
Key Specifications

VSSOP-8 (DGK) package: 2.3 mm × 2.0 mm footprint, 0.5 mm pitch, 1.0 mm max height - optimized for high-density PCB layouts in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (A) | High-impedance node for feedback network connection; requires matched impedance to non-inverting input to minimize bias-current error. |
| 2 | Non-Inverting Input (A) | DC-coupled input capable of operating down to ground; used for single-supply biasing and sensor interface. |
| 3 | Output (A) | Rail-to-rail output capable of sourcing/sinking ≥10 mA; drives 600 Ω loads with ≤0.215 V headroom at 5 V. |
| 4 | V− (GND) | Ground reference for dual-supply operation or system ground in single-supply configurations. |
| 5 | Non-Inverting Input (B) | Independent second channel input; shares same ground and supply references as Channel A. |
| 6 | Inverting Input (B) | Second channel inverting input; supports independent gain-setting networks per channel. |
| 7 | Output (B) | Second rail-to-rail output; electrically isolated from Output A but thermally coupled on die. |
| 8 | V+ | Positive supply rail (2.2–5.5 V); decoupling capacitor required within 1 cm for stability under dynamic load. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV722MX/NOPB | Same silicon, SOIC-8 package (3.91 mm × 4.9 mm vs. VSSOP's 2.3 mm × 2.0 mm); 190°C/W θJA vs. 235°C/W for VSSOP. | Preferred where board area is less constrained and hand-soldering or legacy footprint compatibility is required. | Select LMV722MX/NOPB when thermal management via PCB copper pour is limited and larger package aids assembly yield. |
| TLV272IDR | Lower quiescent current (1.3 mA vs. 1.81 mA at 2.2 V), lower bandwidth (3 MHz vs. 10 MHz), higher input offset (6 mV max). | Better suited for ultra-low-power sensor wake-up circuits where bandwidth <100 kHz suffices. | Choose TLV272IDR only if supply current is the dominant constraint and 10 MHz bandwidth is unnecessary. |
Compared with LMV722MX/NOPB, LMV722MM offers 42% smaller footprint and better high-frequency performance but requires tighter thermal design; versus TLV272IDR, LMV722MM provides 3.3× higher bandwidth and 42% lower input offset at the cost of +39% supply current.

FAQ
What is the maximum capacitive load the LMV722MM can drive without external compensation?
The LMV722MM can directly drive up to 4700 pF in unity-gain configuration without oscillation, as verified in TI's SNOS414I datasheet Figure 23 characterization. This eliminates the need for series isolation resistors in many LCD bias, DAC output, and sensor filter applications. For loads exceeding 4700 pF, TI recommends the resistive-isolation circuit shown in Figure 23 or the feed-forward compensated version in Figure 25. The LMV722MM's internal compensation is optimized for this level of capacitive loading at both 2.2 V and 5 V supplies.
Does the LMV722MM support true single-supply operation with input signals referenced to ground?
Yes, the LMV722MM supports true single-supply operation with input signals down to ground: its input common-mode voltage range extends to −0.3 V (at 25°C) and up to 4.1 V at 5 V supply, satisfying the "includes ground" specification. This enables direct interfacing with grounded sensors like thermistors, photodiodes, and bridge transducers without level-shifting circuitry. However, input voltages must not exceed −0.3 V to avoid forward-biasing internal ESD diodes; TI recommends clamping protection if negative transients are possible.
What is the guaranteed minimum output current capability of the LMV722MM at 2.2 V supply?
At 2.2 V supply, the LMV722MM guarantees minimum output current of ±10.0 mA (sourcing and sinking) under specified test conditions (VO = 0 V or 2.2 V, VIN(diff) = ±0.5 V), per the "2.2V DC Electrical Characteristics" table in SNOS414I. This enables driving moderate loads such as 220 Ω termination resistors or multiple CMOS inputs. Performance improves at higher supplies: at 5 V, sourcing capability increases to ≥25 mA min, supporting heavier analog multiplexer or display driver loads.
How does the LMV722MM's input offset voltage drift behave over temperature?
The LMV722MM has a typical input offset voltage drift (TCVOS) of 0.6 µV/°C, with no maximum limit specified in the datasheet. At 25°C, typical VOS is −0.08 mV (5 V) or 0.02 mV (2.2 V), and the absolute maximum over full temperature range (−40°C to +85°C) is 3.5 mV. This low drift supports stable DC-coupled gain stages in portable instrumentation where calibration intervals are infrequent. The bipolar input stage contributes to predictable, linear drift behavior - unlike CMOS-input amplifiers that may exhibit discontinuous drift near temperature extremes.
Is the LMV722MM pin-compatible with other dual op-amps in VSSOP-8 packaging?
No, the LMV722MM is not universally pin-compatible with other dual op-amps in VSSOP-8. Its pinout (1:−IN A, 2:+IN A, 3:OUT A, 4:GND, 5:+IN B, 6:−IN B, 7:OUT B, 8:V+) follows TI's standard dual-VSSOP convention but differs from industry alternatives like the MCP6022 (1:+IN A, 2:−IN A, 3:OUT A, etc.) or AD8602 (1:OUT A, 2:−IN A, 3:+IN A, etc.). PCB layout must be verified against the LMV722MM-specific pin diagram in Figure 35 of SNOS414I; substitution requires schematic and layout revision unless the alternative part explicitly states LMV722MM pin compatibility.
