Product details
Overview
LMP7711MKE/NOPB from Texas Instruments is a single-channel, precision CMOS-input operational amplifier optimized for low-noise, low-offset, rail-to-rail output signal conditioning in portable and sensor interface applications. It delivers ±150 μV max input offset voltage, 5.8 nV/√Hz input voltage noise at 1 kHz, 17 MHz gain bandwidth product, 1.15 mA supply current at 5 V, and operates from 1.8 V to 5.5 V supply rails.
For engineers reviewing the LMP7711MKE/NOPB datasheet, LMP7711MKE/NOPB pinout, LMP7711MKE/NOPB application, or LMP7711MKE/NOPB equivalent, key selection criteria include its ultra-low input bias current (100 fA), enable-controlled shutdown (140 nA), rail-to-rail output swing within 25 mV of either rail, and SOT-23-6 packaging for space-constrained designs.
Technical Context
The LMP7711MKE/NOPB employs a proprietary CMOS input stage enabling 100 fA typical input bias current and 5.8 nV/√Hz voltage noise density at 1 kHz. Its high open-loop gain (98 dB min) and 17 MHz GBW support stable closed-loop operation up to unity-gain with capacitive loads ≤120 pF.
It integrates an active enable pin (VEN) that reduces supply current to 140 nA in shutdown mode while maintaining rail-to-rail output capability in active mode. The device supports common-mode input voltage down to −0.3 V and full rail-to-rail output swing across 1.8 V–5.5 V supply range and −40°C to +125°C temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 17 MHz - enables accurate amplification at high closed-loop gains up to ~100× at 170 kHz. |
| Input Offset Voltage (max) | ±150 μV - ensures minimal DC error in precision sensor front-ends and active filter DC bias points. |
| Input Voltage Noise Density | 5.8 nV/√Hz @ 1 kHz - preserves signal integrity in low-level transimpedance and photodiode amplifier stages. |
| Supply Current (active) | 1.15 mA @ 5 V - balances performance and power efficiency for battery-powered instrumentation. |
| Rail-to-Rail Output Swing | Within 25 mV of either rail @ RL = 2 kΩ - maximizes dynamic range in low-voltage (1.8 V) single-supply systems. |
| Enable Pin Shutdown Current | 140 nA - allows aggressive power gating in duty-cycled sensor nodes without external switches. |
| Input Bias Current (max) | 100 fA @ −40°C to +125°C - critical for high-impedance pH, piezoelectric, and photodiode interfaces. |
Pinout & Package
The LMP7711MKE/NOPB is housed in a 6-pin SOT-23 package (TI package code DDC), measuring 2.9 mm × 1.6 mm × 1.1 mm, with exposed pad for thermal enhancement and standard surface-mount compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EN) | Enable control input | Active-high logic: ≥4.6 V enables amplifier; ≤0.4 V places device in 140 nA shutdown mode. |
| 2 (−IN) | Inverting input | High-impedance CMOS node; input bias current ≤100 fA enables >100 MΩ source impedances. |
| 3 (+IN) | Non-inverting input | CMOS input with common-mode range extending to −0.3 V below V−, supporting true single-supply operation. |
| 4 (V−) | Negative supply rail | Ground reference for single-supply use; accepts 0 V minimum; supports rail-to-rail output swing. |
| 5 (V+) | Positive supply rail | Accepts 1.8 V to 5.5 V; PSRR ≥85 dB minimizes supply ripple coupling into output. |
| 6 (OUT) | Amplifier output | Capable of sourcing 46 mA / sinking 23 mA; drives 600 Ω loads while maintaining rail-to-rail swing. |

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 | Zero-drift architecture; 0.1 μV/°C max offset drift vs. LMP7711MKE/NOPB's ±4 μV/°C; higher 17 μV max offset; 0.65 mA supply current. | Better long-term DC stability in temperature-varying environments; lower bandwidth (350 kHz) limits AC signal fidelity. | Select OPA333AIDBVR when ultra-low drift dominates over noise and speed requirements. |
| ADA4522-1ARMZ | Zero-drift, 2.5 nV/√Hz noise, 3 MHz GBW, 1.2 mA supply current, no enable pin, SOIC-8 package. | Superior noise and drift performance but lacks enable function and SOT-23 footprint; requires PCB redesign. | Select ADA4522-1ARMZ only when zero-drift and sub-3 nV/√Hz noise are mandatory and board space permits SOIC-8. |

FAQ
What is the maximum capacitive load the LMP7711MKE/NOPB can drive without oscillation?
The LMP7711MKE/NOPB can directly drive capacitive loads up to 120 pF in unity-gain follower configuration without oscillation, as verified in TI's characterization data. For heavier loads, an isolation resistor (RISO) must be added between the output and the capacitor to maintain phase margin above 45° and prevent peaking or instability.
Does the LMP7711MKE/NOPB support true single-supply operation with input voltages near ground?
Yes, the LMP7711MKE/NOPB supports true single-supply operation: its input common-mode voltage range extends to −0.3 V below V− (i.e., −0.3 V with V− = 0 V), and its rail-to-rail output swings within 25 mV of both rails. This enables direct interfacing with grounded sensors and full utilization of low-voltage ADCs.
What is the typical turn-on time for the LMP7711MKE/NOPB enable function?
The LMP7711MKE/NOPB has a typical turn-on time of 114 ns when transitioning from shutdown (VEN ≤ 0.4 V) to active mode (VEN ≥ 4.6 V) at 5 V supply, per TI's SNOSAP4F datasheet. This enables rapid wake-up in duty-cycled sensor systems without sacrificing power savings.
How does the input voltage noise of the LMP7711MKE/NOPB compare at different supply voltages?
The LMP7711MKE/NOPB's input voltage noise density remains stable at 5.8 nV/√Hz at 1 kHz across its full 1.8 V–5.5 V supply range. At 400 Hz, it increases slightly to 6.8 nV/√Hz (2.5 V) and 7.0 nV/√Hz (5 V), confirming consistent low-noise performance independent of supply voltage.
Is the LMP7711MKE/NOPB qualified for automotive applications?
The LMP7711MKE/NOPB is specified for −40°C to +125°C operating temperature and meets industrial reliability standards, but it is not AEC-Q200 qualified. For automotive under-hood or safety-critical applications, TI recommends AEC-Q200–qualified alternatives such as the OPA2333-Q1; the LMP7711MKE/NOPB is suited for non-safety automotive cabin or infotainment subsystems.
