Product details
Overview
LMV552MMX/NOPB from Texas Instruments is a dual-channel, rail-to-rail output, micropower operational amplifier optimized for battery-powered and space-constrained systems. It delivers 3 MHz unity-gain bandwidth, 37 µA per amplifier supply current, and 93 dB CMRR at 5 V, enabling precision signal conditioning in automotive sensor interfaces and portable instrumentation.
For engineers reviewing the LMV552MMX/NOPB datasheet, LMV552MMX/NOPB pinout, LMV552MMX/NOPB application, or LMV552MMX/NOPB equivalent, key selection criteria include its −40°C to +125°C operating range, 70 mV rail-to-rail output swing with 100 kΩ load, and verified stability under 20 pF capacitive loading - critical for low-noise, single-supply front-end designs.
Technical Context
The LMV552MMX/NOPB employs TI's VIP50 process to achieve exceptional bandwidth-to-power efficiency (3 MHz / 37 µA). Its input stage extends below ground, supporting true single-supply operation down to 2.7 V, while the rail-to-rail output delivers >98% of supply voltage swing at light loads.
It features unity-gain stability with 75° phase margin at 10 kΩ || 20 pF load, but requires external compensation (e.g., isolation resistor or in-loop RC network) when driving >100 pF capacitive loads - a design constraint confirmed across all electrical test conditions in the production datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - supports direct integration into 3.3 V and 5 V systems without level-shifting. |
| Unity-Gain Bandwidth | 3 MHz - enables accurate amplification of audio-band and low-speed sensor signals up to ~300 kHz closed-loop. |
| Supply Current per Channel | 37 µA at 5 V - allows continuous operation for years on coin-cell batteries in always-on monitoring nodes. |
| Input Offset Voltage | 3 mV max at 25°C - ensures ≤0.3% gain error in 100× gain sensor amplifier stages without trimming. |
| CMRR | 93 dB at 25°C - rejects common-mode noise from noisy digital supplies in mixed-signal PCB layouts. |
| Output Swing (100 kΩ) | 70 mV from rail at 5 V - delivers 4.93 Vpp output with 5 V supply, maximizing dynamic range in ADC driver applications. |
| THD+N | 0.003% at 1 kHz, 2 kΩ - preserves signal fidelity in audio preamplifier and precision measurement paths. |
Pinout & Package
LMV552MMX/NOPB is housed in an 8-pin VSSOP package (3.00 mm × 3.00 mm body), optimized for high-density PCB layouts and thermal performance (θJA = 200.3°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or feedback network; rail-to-rail capable. |
| 2 | IN A− | Inverting input of channel A - connects to feedback resistor or summing junction. |
| 3 | IN A+ | Noninverting input of channel A - accepts sensor signal or reference voltage; extends to V−. |
| 4 | V− | Negative supply terminal - tied to ground in single-supply configurations. |
| 5 | IN B+ | Noninverting input of channel B - independent signal path; shares same input voltage range as IN A+. |
| 6 | IN B− | Inverting input of channel B - used for differential sensing or inverting gain configuration. |
| 7 | OUT B | Amplifier B output - fully independent channel; identical AC/DC specs to OUT A. |
| 8 | V+ | Positive supply terminal - accepts 2.7–5.5 V; powers both amplifiers simultaneously. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, micropower op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6022-E/SN | Higher supply current (100 µA/channel), lower GBW (1 MHz), wider VS range (2.7–6.0 V) | Better DC precision (1.5 mV VOS) but insufficient bandwidth for audio-band filtering | Prefer when ultra-low offset dominates over power and speed requirements |
| TLV9002IDR | Lower supply current (60 µA/channel), higher GBW (1 MHz), rail-to-rail I/O, integrated EMI filtering | Superior RF immunity but lacks verified −40°C to +125°C operation per datasheet | Prefer for consumer IoT where extended temperature range is not mandatory |
Compared with MCP6022-E/SN and TLV9002IDR, LMV552MMX/NOPB uniquely balances 3 MHz bandwidth, 37 µA/channel consumption, and automotive-grade temperature range - making it the only option qualified for under-hood sensor signal chains requiring simultaneous speed, efficiency, and ruggedness.

FAQ
What is the maximum capacitive load the LMV552MMX/NOPB can drive without external compensation?
The LMV552MMX/NOPB is characterized for stable operation with up to 20 pF capacitive load at unity gain, maintaining ≥75° phase margin. Driving >100 pF requires external compensation - such as an isolation resistor (5–50 Ω) or in-loop RC network - as confirmed in Figure 26 and Table 1 of the SNOSAQ5H datasheet. Uncompensated use beyond 20 pF risks oscillation in production circuits.
Does the LMV552MMX/NOPB support true single-supply operation with input signals at ground potential?
Yes. The LMV552MMX/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 is explicitly verified across −40°C to +125°C in Section 6.5 CMVR specifications, where CMRR ≥68 dB is ensured from 0 V to 2.1 V at 3 V supply.
What is the typical output voltage swing of the LMV552MMX/NOPB at 5 V supply with 10 kΩ load?
At 5 V supply and 25°C, the LMV552MMX/NOPB delivers a typical output swing of 125–155 mV from each rail with a 10 kΩ load, as specified in Section 6.6 VO parameters. This means the output can reach approximately 4.85 V (high) and 0.15 V (low), preserving >97% of full-scale range for 12-bit ADC interfacing.
Is the LMV552MMX/NOPB qualified for automotive applications per AEC-Q100?
No. While the LMV552MMX/NOPB operates across −40°C to +125°C - a range matching many automotive ambient requirements - it is not officially AEC-Q100 qualified. TI's automotive-qualified equivalents (e.g., LMV552QMMX/NOPB) carry the 'Q' suffix and undergo additional stress testing. Designers must verify qualification status via TI's official part search before deployment in safety-critical automotive systems.
How does the LMV552MMX/NOPB's input voltage noise compare to other micropower op amps?
The LMV552MMX/NOPB specifies 70 nV/√Hz input-referred voltage noise (flatband), significantly lower than typical micropower op amps in its class (often >100 nV/√Hz). Its 4 Hz 1/f noise corner further enhances low-frequency SNR - a verified advantage documented in Figure 10 of SNOSAQ5H, making it suitable for sub-10 Hz sensor applications like seismic or biomedical monitoring.
