Product details
Overview
LMP7702MA/NOPB from Texas Instruments is a dual-channel, precision CMOS-input, rail-to-rail input and output operational amplifier with ±220 µV maximum input offset voltage, 2.5 MHz unity-gain bandwidth, and 1.5 mA supply current per channel at 5 V. It operates from 2.7 V to 12 V single-supply or ±5 V dual-supply and delivers rail-to-rail output swing within 40 mV of either rail-ideal for high-impedance sensor interface and battery-powered instrumentation.
For engineers reviewing the LMP7702MA/NOPB datasheet, LMP7702MA/NOPB pinout, LMP7702MA/NOPB application, or LMP7702MA/NOPB equivalent, key selection criteria include ultra-low input bias current (±200 fA), low input voltage noise (9 nV/√Hz), wide common-mode range (–0.2 V to 5.2 V on 5 V supply), and guaranteed operation across –40°C to +125°C industrial temperature range.
Technical Context
The LMP7702MA/NOPB uses VIP50 CMOS process technology to integrate a complementary rail-to-rail input stage with trimmed NMOS/PMOS offsets, minimizing CMRR glitches near supply rails. Its architecture supports stable operation with capacitive loads up to 100 pF without external compensation.
It features 130 dB open-loop gain, 130 dB CMRR, and 98 dB PSRR at 5 V supply-enabling high-accuracy DC-coupled amplification in precision signal chains where offset drift and power supply rejection directly impact measurement fidelity.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2188AIDR | Lower offset (±25 µV max), higher supply current (1.1 mA/ch), no rail-to-rail input | Better DC accuracy but limited CMVR (to V+ – 1.5 V) - unsuitable for true rail-sensing | Choose when ultra-low offset dominates over input range and power constraints allow +0.4 mA extra per channel |
| ADA4522-2ARZ | Zero-drift architecture, ±0.3 µV offset, 1.2 mA/ch, rail-to-rail output only | Superior long-term drift performance but higher cost and no rail-to-rail input - limits single-supply sensor biasing | Prefer for metrology-grade stability where input common-mode range is not constrained by V– |
Compared with OPA2188AIDR and ADA4522-2ARZ, the LMP7702MA/NOPB uniquely combines rail-to-rail input *and* output with sub-picoamp bias current and 125°C operation-making it the only option among the three for high-impedance, wide-VCM, extended-temperature sensor interfaces requiring minimal PCB area in SOIC-8.

FAQ
What is the maximum operating temperature for the LMP7702MA/NOPB?
The LMP7702MA/NOPB is fully specified from –40°C to +125°C ambient temperature. Its VIP50 process and internal thermal design ensure stable electrical performance-including offset voltage, gain, and bandwidth-across this full industrial temperature range, making it suitable for under-hood automotive and factory-floor applications.
Does the LMP7702MA/NOPB support single-supply operation?
Yes, the LMP7702MA/NOPB supports true single-supply operation from 2.7 V to 12 V. Its rail-to-rail input stage accepts common-mode voltages from V– –0.2 V to V+ +0.2 V, and its rail-to-rail output swings within 40 mV of either supply rail-enabling direct interfacing with 3.3 V or 5 V ADCs without level-shifting circuitry.
What is the input bias current specification for the LMP7702MA/NOPB?
The LMP7702MA/NOPB has a typical input bias current of ±200 fA at 25°C, with a maximum of ±1 pA over the full –40°C to +125°C temperature range. This ultra-low bias enables accurate amplification of signals from high-impedance sources such as photodiodes, pH electrodes, and piezoresistive sensors without introducing measurable loading error.
Can the LMP7702MA/NOPB drive capacitive loads?
The LMP7702MA/NOPB is stable driving capacitive loads up to 100 pF with appropriate layout and supply decoupling. For loads exceeding 100 pF, external series resistance (e.g., 10–50 Ω) at the output is recommended to maintain phase margin. The device does not require external compensation for standard PCB traces or typical ADC input capacitance.
Is the LMP7702MA/NOPB pin-compatible with other dual op-amps in SOIC-8?
No, the LMP7702MA/NOPB uses a non-standard SOIC-8 pinout optimized for dual-amplifier routing: pins 1/7 are outputs, pins 2/3 and 5/6 are inverting/noninverting inputs per channel, and pins 4/8 are supplies. It is not pin-compatible with generic dual op-amps like LM358 or TL082-PCB layout must follow TI's recommended footprint for LMP7702.
