Product details
Overview
LMP7701MA/NOPB from Texas Instruments is a single-channel, precision CMOS-input, rail-to-rail input/output operational amplifier optimized for high-impedance sensor interface and low-power instrumentation. It delivers ±200 µV max input offset voltage, ±200 fA input bias current, 2.5 MHz unity-gain bandwidth, and operates from 2.7 V to 12 V supply across −40°C to +125°C. It is widely used in battery-powered medical sensors and DAC output buffering where precision, low power, and wide common-mode range are critical.
For engineers reviewing the LMP7701MA/NOPB datasheet, LMP7701MA/NOPB pinout, LMP7701MA/NOPB application, or LMP7701MA/NOPB equivalent, key selection criteria include its ultra-low input bias current for photodiode/strain gauge front-ends, rail-to-rail swing within 40 mV of rails at 3 V, CMRR >130 dB at DC, and SOT-23-5 package compatibility with space-constrained portable designs.
Technical Context
The LMP7701MA/NOPB employs VIP50 CMOS process technology to achieve both wide 2.7–12 V supply operation and rail-to-rail input stage with trimmed complementary NMOS/PMOS pairs-reducing CMRR glitches near supply rails. Its input stage enables full common-mode range (−0.2 V to VS + 0.2 V) while maintaining 130 dB CMRR and 130 dB open-loop gain.
Output stage architecture supports rail-to-rail swing (≤40 mV from either rail at 2 kΩ load), 1 mA typical supply current, and 0.9–1.1 V/µs slew rate depending on supply. The device is specified across three voltage conditions (3 V, 5 V, ±5 V), with consistent 2.5 MHz GBW and 9 nV/√Hz input voltage noise at 1 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±200 µV maximum - enables sub-1 mV error in 10× gain signal chains without trimming |
| Input Bias Current | ±200 fA typical - preserves signal integrity in >1 GΩ source impedance applications (e.g., pH electrodes) |
| Supply Voltage Range | 2.7 V to 12 V - supports single-supply 3.3 V systems and dual-supply ±5 V instrumentation |
| Unity-Gain Bandwidth | 2.5 MHz - sufficient for anti-aliasing filters up to ~200 kHz and fast-settling DAC buffers |
| CMRR | 130 dB minimum - rejects common-mode noise in noisy industrial environments (e.g., motor drives) |
| Output Swing | Within 40 mV of rails at 2 kΩ - maximizes dynamic range in low-voltage battery-powered systems |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz - suitable for precision amplification of microvolt-level sensor outputs |
Pinout & Package
Package: 5-pin SOT-23 (DBV), body size 1.60 mm × 2.90 mm, surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output | Amplifier output node; capable of sourcing/sinking ≥25 mA (3 V supply) with rail-to-rail swing |
| 2 | V− | Negative supply terminal; accepts ground or negative rail (down to −5 V in dual-supply mode) |
| 3 | IN+ | Noninverting input; CMOS input with ±200 fA bias current and full rail-to-rail common-mode range |
| 4 | IN− | Inverting input; matched to IN+ for <±200 µV offset and high CMRR performance |
| 5 | V+ | Positive supply terminal; supports up to 12 V; supplies internal bias and output stage |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables operation with input signals extending to V− and V+, and output swing within 40 mV of either rail - critical for 3.3 V ADC interfacing |
| VIP50 CMOS process | Combines wide 2.7–12 V supply range with ultra-low input bias current (±200 fA) - not achievable with standard CMOS op-amps |
| Trimmed complementary input stage | Reduces NMOS/PMOS offset mismatch, delivering 130 dB CMRR even near supply rails - eliminates "glitch" artifacts in R-R amplifiers |
| Low 715 µA supply current | Supports always-on sensor monitoring in battery-powered devices with multi-year runtime (e.g., wearable health monitors) |
| −40°C to +125°C operation | Qualified for automotive under-hood and industrial control environments without derating |
Applications
| High-Impedance Sensor Interface | Battery-Powered Instrumentation |
|---|---|
Use Scenario: Amplifying output of a 10 GΩ piezoresistive pressure sensor in a portable blood pressure monitor. IC Role / Device Role / Timing Role: Precision transimpedance amplifier front-end with ultra-low input bias current to prevent signal loading. Use Value: ±200 fA bias current ensures <0.1% gain error; rail-to-rail output drives 3.3 V SAR ADC directly without level-shifting. |

IC Role / Device Role / Timing Role: High-precision, low-noise active gain stage with minimal phase distortion. Use Value: 9 nV/√Hz input noise prevents degradation of microvolt-level ECG signals; 130 dB PSRR rejects supply ripple. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA333AIDBVR | Lower offset (±10 µV typ), higher supply current (17 µA), same SOT-23-5 package | Better DC accuracy but 24× higher quiescent current - unsuitable for multi-year battery operation | Choose OPA333AIDBVR only when offset drift dominates over power budget |
| ADA4522-1ARMZ | Zero-drift architecture, ±0.3 µV max offset, 1.2 mA supply current, 8-pin MSOP | Superior long-term stability and drift, but incompatible pinout and higher power - requires PCB redesign | Choose ADA4522-1ARMZ for metrology-grade stability where layout change is acceptable |
Compared with OPA333AIDBVR and ADA4522-1ARMZ, the LMP7701MA/NOPB uniquely balances ultra-low input bias current (200 fA), 715 µA supply current, and SOT-23-5 footprint - making it optimal for high-impedance, battery-sensitive applications where zero-drift isn't required.

FAQ
What is the maximum operating temperature for the LMP7701MA/NOPB?
The LMP7701MA/NOPB is fully specified from −40°C to +125°C ambient temperature. Its VIP50 process and thermal design ensure stable offset voltage, CMRR, and gain performance across this full industrial and automotive under-hood range without derating. This makes the LMP7701MA/NOPB suitable for deployment in harsh environments such as engine control units and industrial PLC modules.
Does the LMP7701MA/NOPB support dual-supply operation?
Yes, the LMP7701MA/NOPB supports dual-supply operation with V+ = +5 V and V− = −5 V. Electrical characteristics including CMRR (138 dB), open-loop gain (134 dB), and output swing (within 90 mV of either rail) are explicitly characterized under ±5-V conditions. Its rail-to-rail input stage accepts common-mode voltages from −5.2 V to +5.2 V in this configuration.
What is the input voltage noise density of the LMP7701MA/NOPB?
The LMP7701MA/NOPB has an input voltage noise density of 9 nV/√Hz at 1 kHz, confirmed across 3 V, 5 V, and ±5 V supply conditions. This value remains stable across frequency and temperature, enabling reliable low-noise amplification of microvolt-level signals from thermocouples, strain gauges, and photodiodes without requiring external filtering.
Is the LMP7701MA/NOPB unity-gain stable?
Yes, the LMP7701MA/NOPB is unity-gain stable and characterized with AV = +1 in all electrical tables. Its 2.5 MHz gain-bandwidth product and internal compensation ensure stable operation with capacitive loads ≤100 pF and no peaking or oscillation - verified in TI's SNOSAI9I datasheet Figure 27 (phase margin >60°).
What package options are available for the LMP7701MA/NOPB?
The LMP7701MA/NOPB is offered exclusively in the 5-pin SOT-23 (DBV) package per TI's official orderable addendum. While the LMP7701 family also includes an 8-pin SOIC variant (LMP7701M/NOPB), the "MA/NOPB" suffix specifically denotes the SOT-23-5 version with 1.60 mm × 2.90 mm footprint and lead pitch of 0.95 mm.
