Product details
Overview
LMP7711MKX/NOPB from Texas Instruments is a single-channel, precision CMOS-input operational amplifier with rail-to-rail output, 17 MHz gain bandwidth, ±150 μV max input offset voltage, 5.8 nV/√Hz input voltage noise at 1 kHz, and 1.15 mA supply current at 5 V - designed for high-fidelity sensor interface and transimpedance amplification in low-voltage portable instrumentation.
For engineers reviewing the LMP7711MKX/NOPB datasheet, LMP7711MKX/NOPB pinout, LMP7711MKX/NOPB application, or LMP7711MKX/NOPB equivalent, key selection criteria include its 100 fA input bias current, enable pin functionality (shutdown current = 140 nA), −40°C to +125°C operating range, SOT-23-6 package, and verified performance under 1.8–5.5 V supply.
Technical Context
The LMP7711MKX/NOPB employs a CMOS input stage enabling ultra-low input bias current (≤100 fA) and low input voltage noise (5.8 nV/√Hz), optimized for high-impedance sensor front-ends. Its VIP50 process ensures stable operation across 1.8–5.5 V supply and full rail-to-rail output swing within 25 mV of either rail.
It integrates an active enable pin (VEN) that reduces supply current to 140 nA in shutdown mode while maintaining fast turn-on (114 ns) and turn-off (800 ns) times. The amplifier supports unity-gain stable operation with capacitive loads up to 120 pF and delivers 46 mA sourcing capability at 5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 17 MHz - enables accurate closed-loop amplification at high gains up to ~100 kHz for G = 100. |
| Input Offset Voltage (max) | ±150 μV - ensures ≤150 μV DC error at room temperature, critical for precision DC-coupled signal chains. |
| Input Voltage Noise Density | 5.8 nV/√Hz @ 1 kHz - minimizes noise contribution in low-level analog signal amplification (e.g., photodiode, strain gauge). |
| Supply Current (active) | 1.15 mA @ 5 V - balances speed and power efficiency for battery-powered instrumentation. |
| Output Swing | Within 25 mV of rails @ RL = 2 kΩ - maximizes dynamic range in 3.3 V or lower single-supply systems. |
| Enable Pin Threshold | VEN ≥ 4.6 V enables; VEN ≤ 0.4 V shuts down - compatible with standard 5 V logic and microcontroller GPIO control. |
| Operating Temperature | −40°C to +125°C - qualified for industrial and automotive under-hood sensor signal conditioning. |
Pinout & Package
Package: SOT-23-6 (DDC), 2.9 mm × 1.6 mm footprint, surface-mount, lead-free (NOPB).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; drives loads ≥600 Ω without phase reversal. |
| 2 (−IN) | Inverting input | High-impedance CMOS node; accepts differential or single-ended feedback configurations. |
| 3 (+IN) | Non-inverting input | High-impedance CMOS node; common-mode range extends to −0.3 V below ground. |
| 4 (V−) | Negative supply | Ground reference for single-supply operation; supports true 0 V input common-mode. |
| 5 (V+) | Positive supply | Accepts 1.8–5.5 V; internal regulation ensures stable biasing across voltage range. |
| 6 (EN) | Enable control | Active-high digital input; asserts shutdown state when pulled ≤0.4 V, reducing IQ to 140 nA. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Operates within 25 mV of supply rails at 2 kΩ load - preserves full signal headroom in low-voltage systems. |
| Ultra-low input bias current | ≤100 fA at 25°C - prevents signal corruption in high-impedance sensor interfaces (e.g., pH electrodes, piezoresistive sensors). |
| Integrated enable function | Reduces quiescent current from 1.15 mA to 140 nA - enables duty-cycled operation in energy-constrained IoT nodes. |
| Low-noise CMOS architecture | 5.8 nV/√Hz voltage noise + 0.01 pA/√Hz current noise - optimizes SNR for transimpedance amplifiers up to 100 kΩ feedback. |
| Wide supply voltage range | 1.8 V to 5.5 V - supports direct interfacing with Li-ion, coin-cell, and 3.3 V/5 V system rails without LDO. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA376AIDBVR | Lower noise (4.6 nV/√Hz), no enable pin, 5.5 V max supply, same SOT-23-6 package | Lacks shutdown mode; unsuitable for duty-cycled sensor nodes requiring ultra-low standby IQ | Select when lowest possible noise dominates over power gating needs |
| ADA4522-1ARMZ | Zero-drift architecture, 0.3 μV max offset, higher supply current (1.4 mA), 8-lead MSOP package | Better DC accuracy but larger footprint and no enable; not drop-in for space-constrained PCBs | Select when long-term offset drift <0.005 μV/°C is required over temperature |
Compared with OPA376AIDBVR and ADA4522-1ARMZ, the LMP7711MKX/NOPB uniquely combines enable functionality, 100 fA bias current, and 17 MHz bandwidth in a 6-pin SOT - making it optimal for battery-powered, high-impedance, wideband sensor interfaces where both precision and power control are essential.

FAQ
What is the maximum capacitive load the LMP7711MKX/NOPB can drive without oscillation?
The LMP7711MKX/NOPB is unity-gain stable and can directly drive capacitive loads up to 120 pF without oscillation. For heavier loads, an isolation resistor (RISO) between the output and load is recommended to maintain phase margin above 45° and prevent peaking or instability in closed-loop configurations.
Does the LMP7711MKX/NOPB support single-supply operation with input signals near ground?
Yes. The LMP7711MKX/NOPB features an input common-mode voltage range extending to −0.3 V below V− (ground), enabling true single-supply operation with inputs referenced to 0 V - ideal for interfacing with sensors whose outputs swing near ground.
What is the typical turn-on time for the LMP7711MKX/NOPB enable function?
The LMP7711MKX/NOPB has a typical turn-on time of 114 ns when the enable pin transitions from shutdown (VEN ≤ 0.4 V) to active (VEN ≥ 4.6 V at 5 V supply), allowing rapid activation in time-sliced sensing architectures such as pulsed-light biomedical sensors.
How does the LMP7711MKX/NOPB perform at 1.8 V supply voltage?
At 1.8 V, the LMP7711MKX/NOPB maintains full functionality across −40°C to +125°C, with 1.15 mA supply current (typ), 14 MHz GBW (min), and rail-to-rail output swing within 60 mV of rails - validated per TI's 1.8 V electrical characteristics table for industrial-grade operation.
Is the LMP7711MKX/NOPB pin-compatible with other SOT-23-6 op-amps like the OPA344?
No. While both use SOT-23-6 packages, the LMP7711MKX/NOPB places the enable (EN) pin at position 6 and output (OUT) at position 1 - differing from standard op-amp pinouts (e.g., OPA344 uses OUT at pin 1, but no EN pin). PCB layout must follow TI's DDC package diagram to avoid functional misconnection.
