Product details
Overview
LMV554MT/NOPB from Texas Instruments is a quad rail-to-rail output, ground-sensing operational amplifier optimized for ultra-low-power, wide-bandwidth signal conditioning in battery-powered systems. It delivers 3 MHz gain bandwidth, 1 V/µs slew rate, and 37 µA per amplifier supply current at 5 V, enabling precision sensor front-ends and portable instrumentation with 70 mV rail-to-rail output swing into 100 kΩ.
For engineers reviewing the LMV554MT/NOPB datasheet, LMV554MT/NOPB pinout, LMV554MT/NOPB application, or LMV554MT/NOPB equivalent, key selection criteria include its −40°C to +125°C operating range, 93 dB CMRR, 70 nV/√Hz input voltage noise, and TSSOP-14 package compatibility with space-constrained automotive and industrial PCB layouts.
Technical Context
The LMV554MT/NOPB implements TI's VIP50 process to achieve unity-gain stability with 3 MHz bandwidth while maintaining micropower operation. Its input common-mode range extends to V− (ground in single-supply mode), and its rail-to-rail output stage supports full dynamic range across 2.7 V to 5.5 V supply voltages.
It features low 1/f noise corner (4 Hz) and flatband voltage noise (70 nV/√Hz), making it suitable for DC-coupled, low-frequency sensor amplification where offset drift (3.3 µV/°C) and THD (0.003% at 1 kHz) are critical. Phase margin remains ≥75° with 10 kΩ load and 20 pF capacitive load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 3 MHz - enables stable unity-gain configurations for anti-aliasing and active filter stages up to audio frequencies |
| Supply Current per Amplifier | 37 µA at 5 V - allows four independent channels to operate continuously on coin-cell or energy-harvesting power sources |
| Input Offset Voltage | 3 mV typical at 25°C - supports DC-coupled transducer interfaces without external trimming in cost-sensitive designs |
| CMRR | 93 dB - rejects common-mode noise from noisy digital supplies or shared ground paths in mixed-signal systems |
| Output Swing (100 kΩ) | 70 mV from rail - preserves >98% of available dynamic range in 3.3 V or 5 V single-supply data acquisition |
| Input Voltage Noise | 70 nV/√Hz at 1 kHz - ensures sub-microvolt RMS noise in 10 Hz–10 kHz sensor signal chains |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive, industrial motor control, and outdoor environmental monitoring |
Pinout & Package
LMV554MT/NOPB is housed in a 14-pin TSSOP (PW) package measuring 5.00 mm × 4.40 mm, optimized for thermal performance (RθJA = 134.9°C/W) and high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| 2, 6, 9, 13 | −IN A, −IN B, −IN C, −IN D | Inverting inputs - accept differential or single-ended feedback networks for configurable gain and filtering |
| 3, 5, 10, 12 | +IN A, +IN B, +IN C, +IN D | Noninverting inputs - support ground-referenced sensor inputs with common-mode range down to V− |
| 4 | V+ | Positive supply - accepts 2.7 V to 5.5 V; powers all four amplifiers simultaneously |
| 11 | V− | Negative supply - connects to ground in single-supply operation; enables true ground-sensing capability |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher supply current (550 µA/channel), wider GBW (6.4 MHz), but no guaranteed ground-sensing input | Better for higher-speed signal chains; unsuitable for true 0 V-referenced sensor inputs | Select when bandwidth >3 MHz is required and ground-sensing is not needed |
| LPV521MG/NOPB | Single-channel, lower supply current (320 nA), much lower GBW (155 kHz), rail-to-rail I/O | Optimized for nano-power, low-frequency sensing only; not a functional replacement for quad-channel needs | Select only for ultra-low-power single-channel applications where quad integration is unnecessary |
Compared with TLV2464IDR and LPV521MG/NOPB, LMV554MT/NOPB uniquely balances 3 MHz bandwidth, quad integration, ground-sensing capability, and micropower operation-making it the only option among the three that supports multi-sensor, battery-powered, DC-coupled signal chains across automotive and industrial temperature ranges.

FAQ
What is the maximum capacitive load the LMV554MT/NOPB can drive without external compensation?
The LMV554MT/NOPB maintains ≥75° phase margin with up to 20 pF capacitive load when driving a 10 kΩ resistive load. For loads exceeding 20 pF-such as ADC input capacitance or long PCB traces-external compensation (e.g., isolation resistor or in-the-loop RC network) is required to prevent oscillation. The datasheet provides specific RS and CF values for 50–150 pF loads.
Does the LMV554MT/NOPB support true single-supply operation with ground-referenced inputs?
Yes. The LMV554MT/NOPB features an input common-mode voltage range extending to V−, allowing direct connection of 0 V-referenced sensors (e.g., thermistors, bridge transducers) in single-supply configurations. This eliminates the need for level-shifting circuitry and simplifies biasing in 3.3 V or 5 V systems.
What is the typical total supply current for all four amplifiers in the LMV554MT/NOPB at 5 V?
The LMV554MT/NOPB draws 37 µA per amplifier at 5 V and 25°C, resulting in a typical total quiescent current of 148 µA for all four channels. Over temperature (−40°C to +125°C), maximum supply current per amplifier is 54 µA, yielding ≤216 µA total-critical for battery-life calculations in always-on sensor nodes.
Can the LMV554MT/NOPB be used in automotive applications requiring AEC-Q100 qualification?
No. The LMV554MT/NOPB is not AEC-Q100 qualified. However, it operates across −40°C to +125°C and is widely deployed in non-safety-critical automotive cabin systems (e.g., HVAC sensors, infotainment ambient light control). For AEC-Q100-compliant alternatives, consult TI's automotive-grade amplifier portfolio.
How does the LMV554MT/NOPB's input voltage noise compare to other micropower op amps?
The LMV554MT/NOPB delivers 70 nV/√Hz input voltage noise at 1 kHz-significantly lower than typical micropower op amps (often >100 nV/√Hz). Its 4 Hz 1/f noise corner further reduces low-frequency drift, making it superior for DC-coupled applications like precision weigh scales or gas sensor amplifiers where integrated noise dominates error budgets.
