Product details
Overview
LMP7704MA/NOPB from Texas Instruments is a quad-channel, precision CMOS-input, rail-to-rail input and output operational amplifier optimized for high-impedance sensor interface and battery-powered instrumentation. It delivers ±220 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 rails - enabling accurate signal conditioning in low-voltage, low-power analog front-ends.
For engineers reviewing the LMP7704MA/NOPB datasheet, LMP7704MA/NOPB pinout, LMP7704MA/NOPB application, or LMP7704MA/NOPB equivalent, key selection criteria include ultra-low input bias current for photodiode/strain gauge amplification, rail-to-rail swing within 40 mV of rails at 3 V supply, guaranteed performance across −40°C to +125°C, and SOIC-14 package compatibility with space-constrained PCB layouts.
Technical Context
The LMP7704MA/NOPB employs VIP50 CMOS process technology to achieve simultaneous rail-to-rail input common-mode range (down to V− − 0.2 V and up to V+ + 0.2 V) and rail-to-rail output swing (within 40 mV of either rail at RL = 2 kΩ), while maintaining 130 dB CMRR and 130 dB open-loop gain. Its complementary input stage is laser-trimmed to minimize CMRR glitches typical of rail-to-rail amplifiers.
It supports single-supply operation from 2.7 V to 12 V or dual-supply ±5 V, with 9 nV/√Hz input voltage noise at 1 kHz and 1 fA/√Hz input current noise at 100 kHz - making it suitable for high-gain, low-noise transimpedance and precision buffer applications where leakage and offset drift must be minimized.

IC Role / Device Role / Timing Role: Precision DC-coupled buffer and gain stage before sigma-delta ADC, rejecting common-mode noise from shared ground. Use Value: 130 dB CMRR suppresses 60-Hz pickup; ±220 µV VOS contributes <0.005% error in 4.5-V full-scale measurement range. |
| DAC Output Buffer | Active Filter Stage |
|
Use Scenario: Driving a 12-bit DAC's output into a 10-kΩ load while maintaining monotonicity and settling time <1 µs. IC Role / Device Role / Timing Role: Unity-gain voltage follower with low output impedance and minimal capacitive loading sensitivity. Use Value: 2.5-MHz GBW ensures <0.1% gain error up to 200 kHz; 40-mV rail margin prevents clipping on 3.3-V DAC outputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2189IDR | Lower VOS (±5 µV max), higher supply current (1.3 mA/channel), no rail-to-rail input | Better DC accuracy but incompatible with VCM near rails; requires level-shifting for single-supply sensor nodes | Select when ultra-low offset dominates over input range and power budget allows +2× current draw |
| ADA4522-4ARUZ | Zero-drift architecture, 25 nV/°C TCVOS, 1.8 MHz GBW, 1.2 mA/channel supply current | Superior long-term drift stability but lower bandwidth; not suitable for >100-kHz active filters | Select for metrology-grade DC stability where 1/f noise and aging effects outweigh bandwidth needs |
Compared with LMP7704MA/NOPB, OPA2189IDR trades rail-to-rail input capability for microvolt-level offset, while ADA4522-4ARUZ sacrifices bandwidth and increases quiescent current to eliminate 1/f noise - making LMP7704MA/NOPB optimal for wide-input-range, moderate-bandwidth, low-power precision analog systems.

FAQ
What is the maximum operating supply voltage for the LMP7704MA/NOPB?
The LMP7704MA/NOPB supports a maximum supply voltage of 13.2 V (absolute maximum rating), with recommended operation from 2.7 V to 12 V. At 12 V, it maintains full rail-to-rail input/output swing and specified AC performance including 2.5 MHz bandwidth and 130 dB CMRR - verified across −40°C to +125°C.
Does the LMP7704MA/NOPB support true rail-to-rail input common-mode range?
Yes, the LMP7704MA/NOPB achieves rail-to-rail input operation: its common-mode voltage range extends from V− − 0.2 V to V+ + 0.2 V. This is enabled by a trimmed complementary CMOS input stage and confirmed in datasheet Section 7.5 (CMVR = –0.2 V to 5.2 V at 5 V supply), allowing direct interfacing with sensors referenced to either rail.
What is the output drive capability of each amplifier in the LMP7704MA/NOPB?
Each amplifier in the LMP7704MA/NOPB delivers ±25 mA output current (sourcing and sinking) into loads down to 2 kΩ. At 3 V supply, output swing remains within 40 mV of both rails under this load - enabling direct driving of LEDs, small relays, or ADC reference buffers without external boost circuitry.
How does the LMP7704MA/NOPB handle input bias current over temperature?
The LMP7704MA/NOPB maintains ultra-low input bias current: ±200 fA typical at 25°C, rising to ±400 pA maximum at 125°C. This is documented in Section 7.5 Electrical Characteristics (3-V table) and reflects the inherent stability of its VIP50 CMOS process - critical for maintaining accuracy in high-impedance pH or piezoelectric sensor circuits over full temperature range.
Is the LMP7704MA/NOPB pin-compatible with other quad op-amps in SOIC-14 packages?
No - the LMP7704MA/NOPB uses a proprietary pinout optimized for low crosstalk and layout symmetry (e.g., V+ on Pin 4, V− on Pin 11, alternating IN+/IN− per channel). It is not pin-compatible with generic SOIC-14 quad op-amps like LM324 or TL074; PCB redesign is required for substitution.
