Product details
Overview
LMV652MMX/NOPB from Texas Instruments is a dual-channel, rail-to-rail output, low-voltage operational amplifier optimized for battery-powered and space-constrained systems. It delivers 12 MHz unity-gain bandwidth, 118 μA per amplifier supply current, 1.5 mV max input offset voltage, 100 dB CMRR, and operates from 2.7 V to 5.5 V - enabling precision signal conditioning in portable instrumentation and automotive sensor interfaces.
For engineers reviewing the LMV652MMX/NOPB datasheet, LMV652MMX/NOPB pinout, LMV652MMX/NOPB application, or LMV652MMX/NOPB equivalent, key selection criteria include its 12 MHz bandwidth at ultra-low quiescent current, rail-to-rail output swing within 120 mV of rails (at 2 kΩ), −40°C to +125°C operating range, and VSSOP-8 package compatibility with high-density PCB layouts.
Technical Context
The LMV652MMX/NOPB implements TI's VIP50 process to achieve exceptional bandwidth-to-power efficiency: 12 MHz gain-bandwidth product with only 118 μA per channel. Its input stage supports common-mode voltage down to the negative rail (ground-sensing), while the rail-to-rail output stage ensures maximum dynamic range in single-supply configurations.
Stability is unity-gain guaranteed but degrades above 100 pF capacitive load; external compensation (e.g., series RISO or in-the-loop RC) is required for driving higher CL. Input-referred voltage noise is flat at 17 nV/√Hz (1 kHz–100 kHz), with a low 1/f corner at 4 Hz - critical for low-frequency sensor amplification without DC drift penalties.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - supports direct connection to Li-ion battery (3.0–4.2 V) or regulated 3.3 V/5 V rails without level-shifting. |
| Unity-Gain Bandwidth | 12 MHz - enables stable amplification of audio-band and low-MHz sensor signals (e.g., ultrasonic transducer outputs) with minimal phase lag. |
| Input Offset Voltage (max) | ±1.5 mV - ensures ≤0.3% gain error in 100× inverting configurations at room temperature, reducing calibration burden in precision front-ends. |
| CMRR / PSRR | 100 dB / 95 dB - rejects power supply ripple and common-mode interference in noisy automotive or industrial environments. |
| Output Swing (2 kΩ) | 120 mV from rail (high), 130 mV from rail (low) at 5 V - delivers >4.7 Vpp usable output in single-supply 5 V systems, maximizing ADC utilization. |
| THD+N @ 1 kHz | 0.003% at 2 kΩ - preserves signal fidelity in audio preamps and high-resolution data acquisition paths without harmonic contamination. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive sensors, industrial motor controllers, and extended-life portable equipment. |
Pinout & Package
LMV652MMX/NOPB is housed in an 8-pin VSSOP (DGK) package measuring 3.00 mm × 3.00 mm, optimized for thermal performance (θJA = 200.3°C/W) and high-density routing on compact PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Output, Channel A | Amplified signal source for first channel; rail-to-rail capable, drives ≥2 kΩ loads directly. |
| 2 (−IN A) | Inverting Input, Channel A | High-impedance node (120 nA bias current) for feedback networks and inverting gain configurations. |
| 3 (+IN A) | Noninverting Input, Channel A | Ground-sensing input - accepts signals from 0 V up to V+ − 0.1 V in single-supply operation. |
| 4 (V−) | Negative Supply Input | Connects to ground or negative rail; defines lower reference for input common-mode and output swing. |
| 5 (+IN B) | Noninverting Input, Channel B | Independent second channel input; identical electrical specs to Channel A, enabling dual-sensor buffering. |
| 6 (−IN B) | Inverting Input, Channel B | Separate inverting node for Channel B; supports independent gain-setting resistors per channel. |
| 7 (OUT B) | Output, Channel B | Second rail-to-rail output; electrically isolated from OUT A - no crosstalk in differential or dual-path designs. |
| 8 (V+) | Positive Supply Input | Accepts 2.7–5.5 V; PSRR of 95 dB suppresses noise from switching regulators feeding this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output stage | Delivers full 4.88 Vpp swing at 5 V supply into 2 kΩ, maximizing dynamic range for 12-bit+ ADCs without external level-shifting. |

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 |
|---|---|---|---|
| TLV6742IDGKR | Higher supply current (240 μA/channel), 10 MHz GBW, 0.5 mV max VOS, same VSSOP-8 package. | Better DC precision but 2× higher power draw - suitable where offset dominates over battery life. | Select TLV6742IDGKR when <0.5 mV offset is mandatory and system can tolerate +122 μA/channel extra current. |
| OPA2313AIDGKR | Lower bandwidth (1 MHz), 50 μA/channel, rail-to-rail I/O, same VSSOP-8 footprint. | Optimized for sub-1 MHz sensor signals (e.g., RTDs, strain gauges); insufficient for audio or fast transients. | Choose OPA2313AIDGKR only for ultra-low-power DC-coupled applications where bandwidth <2 MHz is acceptable. |
Compared with TLV6742IDGKR and OPA2313AIDGKR, LMV652MMX/NOPB uniquely balances 12 MHz bandwidth, 118 μA/channel, and ±1.5 mV offset - making it the optimal choice for battery-powered systems needing both speed and efficiency without sacrificing precision.

FAQ
What is the maximum capacitive load LMV652MMX/NOPB can drive without external compensation?
The LMV652MMX/NOPB remains stable with capacitive loads up to 100 pF. Beyond that, phase margin degrades significantly - for example, at 150 pF, phase margin drops to 39.4°. To drive larger loads (e.g., LCD bias lines or long cables), use in-the-loop RC compensation or a series isolation resistor (RISO = 340 Ω for 150 pF) as specified in TI's SNOSAI7K datasheet Figure 35 and Table 1. LMV652MMX/NOPB must not be operated near instability thresholds in production designs.
Does LMV652MMX/NOPB support true single-supply operation with input signals at ground potential?
Yes. LMV652MMX/NOPB features an input common-mode voltage range that includes the negative rail (V−), allowing direct amplification of 0 V–referenced signals such as thermistor dividers, bridge transducers, or current-sense shunts in single-supply configurations. This ground-sensing capability eliminates the need for level-shifting circuitry and simplifies biasing in 3.3 V or 5 V systems where V− = GND.
How does the 17 nV/√Hz input voltage noise of LMV652MMX/NOPB compare to other low-power op-amps?
At 17 nV/√Hz (1 kHz), LMV652MMX/NOPB delivers significantly lower broadband noise than typical micropower op-amps (e.g., MCP6002: 29 nV/√Hz). Its 4 Hz 1/f corner further minimizes low-frequency drift - critical for DC-stable sensor interfaces. This noise performance is achieved without increasing supply current, making LMV652MMX/NOPB uniquely suited for high-fidelity, low-power analog front-ends where both speed and signal integrity matter.
Can LMV652MMX/NOPB operate reliably at 2.7 V supply voltage?
Yes. LMV652MMX/NOPB is fully specified and production-tested from 2.7 V to 5.5 V. At 2.7 V, it maintains 12 MHz gain-bandwidth, 118 μA per amplifier supply current, and rail-to-rail output swing (within 185 mV of rails at 2 kΩ). This makes LMV652MMX/NOPB ideal for systems powered directly by partially discharged Li-ion cells or low-dropout regulators in energy-harvesting applications.
What is the thermal resistance (θJA) of the VSSOP-8 package used by LMV652MMX/NOPB?
The LMV652MMX/NOPB in DGK (VSSOP-8) package has a junction-to-ambient thermal resistance (θJA) of 200.3°C/W, measured on a standard JEDEC 2-layer board. This value assumes standard copper pour and via placement; actual board layout can reduce θJA by up to 30% with enhanced thermal pads and internal ground planes. The device's 118 μA/channel dissipation results in negligible self-heating (<0.5°C rise) under typical operating conditions.
