Product details
Overview
LMV862MM/NOPB from Texas Instruments is a dual-channel, CMOS-input, rail-to-rail output operational amplifier optimized for EMI-sensitive signal conditioning in precision sensor interfaces and medical diagnostics. It delivers 30 MHz gain-bandwidth, 18 V/µs slew rate, 1 mV max input offset voltage, and 105 dB EMI rejection ratio at 1.8 GHz - enabling robust operation in noisy industrial or portable environments with photodiode preamps and weight scale systems.
For engineers reviewing the LMV862MM/NOPB datasheet, LMV862MM/NOPB pinout, LMV862MM/NOPB application, or LMV862MM/NOPB equivalent, this page provides verified specifications, validated 8-pin VSSOP package details, confirmed EMI-hardened performance metrics, and two functionally comparable alternatives for sensor front-end and low-power instrumentation designs.
Technical Context
The LMV862MM/NOPB implements a unity-gain-stable CMOS input stage with input common-mode range extending to ground and rail-to-rail output swing. Its EMI hardening is achieved via internal layout and circuit techniques that suppress RF-induced offset shifts - verified by EMIRR measurements up to 2.4 GHz.
It maintains stability driving capacitive loads up to 200 pF without external compensation and achieves 93 dB PSRR and CMRR over 2.7–5.5 V supply range, supporting high-accuracy DC-coupled amplification in battery-powered and automotive-adjacent applications.
Key Specifications

|---|---|
| Supply Voltage | 2.7 V to 5.5 V - supports single-supply operation from Li-ion (3.3 V) or USB (5 V) rails without level-shifting. |
| Gain Bandwidth Product | 30 MHz - enables stable closed-loop gain ≥10 at 3 MHz for anti-aliasing filter buffering. |
| Input Offset Voltage | ≤1 mV max - ensures ≤0.02% error in 50 mV full-scale pressure sensor outputs. |
| EMI Rejection Ratio | 105 dB at 1.8 GHz - reduces RF-induced offset drift to <1 µV under GSM/UMTS band interference. |
| Slew Rate | 18 V/µs - supports 10 VPP signals up to ~280 kHz without distortion in unity-gain buffers. |
| Output Drive Current | ±67 mA - drives 10 kΩ loads to rail with <5 mV drop and sustains 200 pF capacitive loads stably. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive sensor modules and industrial PLC analog inputs. |
Pinout & Package
LMV862MM/NOPB is housed in an 8-pin VSSOP (Very Small Outline Package) with 0.65 mm pitch, 3.0 mm × 3.0 mm body, and exposed thermal pad for enhanced power dissipation in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUTA) | Channel A output | Rail-to-rail voltage source capable of sourcing/sinking ±67 mA into 10 kΩ load. |
| 2 (−INA) | Channel A inverting input | CMOS node with 0.1 pA bias current; accepts common-mode voltages down to −0.1 V. |
| 3 (+INA) | Channel A non-inverting input | High-impedance node for precision reference or sensor signal routing; matched to Pin 2 for CMRR. |
| 4 (GND) | Analog ground | Reference return for both channels; must be tied to low-impedance PCB ground plane. |
| 5 (+INB) | Channel B non-inverting input | Independent high-Z input for second sensor channel or feedback path in dual-stage filters. |
| 6 (−INB) | Channel B inverting input | Matched to Pin 5; supports differential configurations with >93 dB CMRR up to 100 kHz. |
| 7 (OUTB) | Channel B output | Functionally identical to Pin 1; enables independent gain stages or parallel drive capability. |
| 8 (V+) | Positive supply | Accepts 2.7–5.5 V; decoupling capacitor (0.1 µF) required within 2 mm of this pin. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C TCVOS vs. LMV862MM/NOPB's 0.7 µV/°C; higher 350 nA supply current. | Better DC accuracy for long-term thermocouple monitoring; less suited for wideband photodiode pulse preservation. | Select when microvolt-level drift over temperature dominates over RF immunity and bandwidth. |
| TLV2462IDR | Lower 6.4 MHz GBW and 1.6 V/µs slew rate; no specified EMIRR; 1.2 mV VOS max. | Adequate for DC-coupled load cell interfaces below 100 kHz; lacks EMI hardening for wireless-adjacent medical devices. | Select for cost-sensitive, non-EMI-critical industrial analog I/O where 30 MHz bandwidth is unnecessary. |
Compared with OPA2333AIDR and TLV2462IDR, LMV862MM/NOPB uniquely balances 30 MHz bandwidth, 105 dB EMI rejection at cellular frequencies, and 1 mV VOS in an 8-pin VSSOP - making it optimal for battery-powered diagnostic tools requiring both speed and noise resilience.

FAQ
What is the maximum capacitive load the LMV862MM/NOPB can drive without external compensation?
The LMV862MM/NOPB is specified to remain stable with capacitive loads up to 200 pF directly on its output pins under unity-gain conditions. This capability simplifies anti-aliasing filter integration and eliminates the need for isolation resistors in most sensor buffer applications. For loads exceeding 200 pF, a series isolation resistor (e.g., 50 Ω) between the LMV862MM/NOPB output and the capacitive load restores phase margin. Verified stability data appears in Figure 26 of the SNOSAZ5C datasheet.
Does the LMV862MM/NOPB support rail-to-rail input common-mode voltage range?
The LMV862MM/NOPB features a rail-to-rail *output*, but its input common-mode voltage range extends from −0.1 V to (V+ − 1.2 V), which includes ground but does not reach the positive rail. At 3.3 V supply, usable input range is −0.1 V to 2.1 V; at 5 V, it is −0.1 V to 3.9 V. This design enables accurate sensing of signals referenced to ground while maintaining >65 dB CMRR across the supported range, as confirmed in the Electrical Characteristics table.
How does the EMI hardening of the LMV862MM/NOPB improve system-level robustness?
The LMV862MM/NOPB's EMI hardening reduces RF-induced input offset voltage shifts - quantified by EMIRR of 105 dB at 1.8 GHz - meaning a 100 mVP RF tone induces only ~0.3 µV of effective offset change. This eliminates visible artifacts in oscilloscope waveforms during GSM transmission and removes the need for external RF filtering in portable ECG or pulse oximeter designs, directly improving time-to-market and reducing PCB layer count.
What is the typical supply current of the LMV862MM/NOPB at 3.3 V and 25°C?
At 3.3 V supply and 25°C ambient temperature, the LMV862MM/NOPB draws 4.42 mA typical supply current (per device, i.e., for both channels combined), with a guaranteed maximum of 5.77 mA across temperature and process variation. This value is measured under no-load conditions with both amplifiers operating - critical for estimating battery life in portable medical devices powered by coin cells or single Li-ion batteries.
Can the LMV862MM/NOPB be used in single-supply 3.3 V systems with ground-referenced sensors?
Yes - the LMV862MM/NOPB supports single-supply operation from 2.7 V to 5.5 V and accepts input common-mode voltages down to −0.1 V, enabling direct interfacing with ground-referenced sensors like resistive bridges or photodiodes. Its rail-to-rail output delivers full 0–3.3 V swing into 10 kΩ loads, and the 1 mV max input offset ensures minimal baseline error in 12-bit+ data acquisition systems using the LMV862MM/NOPB as a front-end buffer.
