Product details
Overview
LMV552MM/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 portable instrumentation and automotive sensor interfaces.
For engineers reviewing the LMV552MM/NOPB datasheet, LMV552MM/NOPB pinout, LMV552MM/NOPB application, or LMV552MM/NOPB equivalent, this page provides verified electrical specifications, package-confirmed pin functions, real-world application contexts, and two validated alternative parts with documented functional and application-level differences.
Technical Context
The LMV552MM/NOPB implements TI's VIP50 process to achieve exceptional bandwidth-to-power efficiency (3 MHz / 37 µA). Its input common-mode range extends below ground, supporting single-supply operation down to 2.7 V while maintaining rail-to-rail output swing within 70 mV of either rail under 100-kΩ load.
It features unity-gain stability, 70 nV/√Hz input voltage noise, and 0.003% THD+N at 1 kHz - characteristics confirmed across −40°C to +125°C. Phase margin remains ≥75° with 10 kΩ load and 20 pF capacitive load, but external compensation is required for CL > 100 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7 V to 5.5 V - supports direct integration into 3.3 V and 5 V systems without level-shifting. |
| Bandwidth | 3 MHz GBW - enables stable amplification of audio-band and low-speed sensor signals up to ~300 kHz in closed-loop configurations. |
| Supply Current | 37 µA per amplifier - allows continuous operation for years on coin-cell batteries in always-on monitoring circuits. |
| Input Offset Voltage | 1–3 mV (typ) - ensures <1% gain error in 100× gain stages without trimming, suitable for DC-coupled sensor front-ends. |
| CMRR | 93 dB (typ at 5 V) - rejects common-mode noise from noisy power rails or shared grounds in mixed-signal PCBs. |
| Output Swing | 70 mV from rail (100-kΩ load, 5 V supply) - maximizes dynamic range in single-supply data acquisition with 12-bit+ ADCs. |
| THD+N | 0.003% at 1 kHz, 2 kΩ - preserves signal fidelity in audio preamps and precision analog filters without distortion artifacts. |
Pinout & Package
LMV552MM/NOPB is housed in an 8-pin VSSOP (DGK) package measuring 3.00 mm × 3.00 mm, optimized for high-density PCB layouts and thermal performance (θJA = 200.3°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT A | Output, Channel A | Amplified output of first op-amp; rail-to-rail capable, drives loads ≥10 kΩ directly. |
| 2: –IN A | Inverting Input, Channel A | Differential input node for channel A; accepts signals down to V− (ground in single-supply use). |
| 3: +IN A | Noninverting Input, Channel A | Differential input node for channel A; supports input common-mode range to V−. |
| 4: V− | Negative Supply | Ground reference for single-supply operation or negative rail in split-supply designs. |
| 5: +IN B | Noninverting Input, Channel B | Differential input node for second op-amp; electrically isolated from channel A inputs. |
| 6: –IN B | Inverting Input, Channel B | Differential input node for channel B; shares same input stage architecture as channel A. |
| 7: OUT B | Output, Channel B | Amplified output of second op-amp; independent output stage, no crosstalk with channel A. |
| 8: V+ | Positive Supply | Primary power rail; operates from 2.7 V to 5.5 V; supplies both amplifiers simultaneously. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 70 mV of V+ and V− under 100-kΩ load - preserves full ADC input range in 3.3 V systems. |
| Ground-sensing input | Input common-mode includes V− - enables direct interface with 0 V-referenced sensors (e.g., thermistors, bridge transducers). |
| Ultra-low noise | 70 nV/√Hz flatband voltage noise - maintains SNR > 80 dB in 10 kHz bandwidth sensor amplifiers. |
| High PSRR | 90 dB (typ at 5 V) - suppresses ripple from switching regulators powering mixed-signal subsystems. |
| Wide temperature range | Operates from −40°C to +125°C - qualified for under-hood automotive and industrial control environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, micropower, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6022-E/SN | Higher supply current (100 µA/channel), lower bandwidth (1 MHz), same VSSOP-8 package. | Better offset drift (1.5 µV/°C vs 3.3 µV/°C) but reduced bandwidth limits audio and fast sensor response. | Select when ultra-low drift dominates over bandwidth and power; not drop-in due to higher IQ and lower GBW. |
| TSV912IDT | Lower supply current (31 µA/channel), same 3 MHz GBW, wider supply range (2.5–5.5 V), same VSSOP-8. | Improved input bias current (1 pA vs 38 nA) benefits high-Z pH or photodiode sensors; lower VOS (1.5 mV max). | Preferred for ultra-high-impedance sources; pin-compatible and functionally similar, but requires validation of noise performance (75 nV/√Hz). |
Compared with LMV552MM/NOPB, MCP6022-E/SN trades bandwidth and power efficiency for improved drift stability, while TSV912IDT offers lower power and better input specs at comparable speed - making it the closest functional match for new designs prioritizing source impedance and long-term calibration.

FAQ
What is the operating temperature range for LMV552MM/NOPB?
The LMV552MM/NOPB is specified to operate from −40°C to +125°C, meeting industrial and automotive under-hood requirements. This range is validated across all key parameters including input offset voltage, CMRR, and output swing - ensuring reliable performance in harsh environments without derating.
Does LMV552MM/NOPB support single-supply operation?
Yes, LMV552MM/NOPB supports true single-supply operation from 2.7 V to 5.5 V. Its input common-mode range extends to V− (including ground), and its rail-to-rail output swings within 70 mV of both supply rails under 100-kΩ load - enabling direct interfacing with 3.3 V microcontrollers and ADCs.
What is the maximum capacitive load LMV552MM/NOPB can drive without external compensation?
LMV552MM/NOPB maintains ≥75° phase margin with up to 20 pF capacitive load when driving a 10 kΩ resistive load. For loads exceeding 100 pF, external compensation (e.g., isolation resistor or in-the-loop RC network) is required to prevent oscillation - as confirmed in Figure 26 and Table 1 of the datasheet.
How does the input offset voltage of LMV552MM/NOPB vary with temperature?
LMV552MM/NOPB exhibits an input offset voltage drift of 3.3 µV/°C (typical) over −40°C to +125°C. At 25°C, VOS is 1–3 mV (typ), rising to ≤4.5 mV across the full temperature range - a specification validated in both 3 V and 5 V operating conditions per Section 6.5 and 6.6 of the datasheet.
Is LMV552MM/NOPB pin-compatible with other dual op-amps in VSSOP-8 packages?
LMV552MM/NOPB follows the industry-standard VSSOP-8 pinout for dual op-amps (OUT A, –IN A, +IN A, V−, +IN B, –IN B, OUT B, V+), matching TI's own TLV2462 and many competitors' offerings. However, electrical compatibility - especially regarding supply current, bandwidth, and noise - must be verified per application; pinout alone does not guarantee drop-in replacement.
