Texas Instruments TLE2071CP

Overview

TLE2071CP from Texas Instruments is a single-channel JFET-input operational amplifier optimized for high-voltage, low-noise, and high-speed precision applications. It delivers 10.6 MHz unity-gain bandwidth, 32 V/μs slew rate, ±19 V supply capability, 17 nV/√Hz input voltage noise at 1 kHz, and ±300 µV typical input offset voltage - enabling accurate signal conditioning in oscilloscopes, electricity meters, and AC drive power stages.

For engineers reviewing the TLE2071CP datasheet, TLE2071CP pinout, TLE2071CP application, or TLE2071CP equivalent, this device supports rail-to-rail input operation, wide common-mode range (±11 V at ±15 V supplies), low bias current (±15 pA), and unity-gain stability - critical for high-fidelity data acquisition and battery-powered test equipment design.

Technical Context

The TLE2071CP uses Excalibur JFET-input architecture with on-chip Zener trimming for DC precision, achieving low offset drift (3.2 µV/°C) and high CMRR (98 dB at ±15 V). Its internal compensation ensures unity-gain stability while maintaining 56° phase margin with 2 kΩ load and 25 pF capacitive load.

It operates across 0°C to 70°C ambient temperature, supports ±2.25 V to ±19 V dual supplies, and features differential input voltage tolerance up to the supply rails - allowing direct interfacing with sensors operating near supply limits without external level-shifting.

FAQ

What is the maximum supply voltage for the TLE2071CP?

The TLE2071CP supports dual-supply operation from ±2.25 V up to ±19 V, with absolute maximum ratings of ±38 V on VCC+ relative to VCC–. This wide range allows direct integration into ±15 V industrial systems and high-voltage sensor interfaces without external regulators or level shifters. Always observe derating curves in the datasheet for thermal limits at elevated voltages.

Does the TLE2071CP require external offset nulling in standard applications?

The TLE2071CP has a maximum input offset voltage of ±4 mV at 25°C - sufficient for most medium-precision applications like DMM front-ends and motor current sensing. Offset nulling via Pins 1 and 5 is optional and only needed in ultra-stable DC-coupled systems (e.g., laboratory-grade integrators) where drift below ±100 µV is required. Most designs operate successfully without trimming.

Is the TLE2071CP unity-gain stable, and what load capacitance can it drive?

Yes, the TLE2071CP is internally compensated for unity-gain stability. It drives up to 25 pF capacitive load with ≥56° phase margin into a 2 kΩ resistive load. For loads exceeding 25 pF (e.g., long cables or ADC input capacitance), a series resistor (10–100 Ω) should be placed directly at the output pin to isolate capacitance and maintain stability.

How does the TLE2071CP compare to the TLE2071ACP in terms of precision?

The TLE2071ACP offers tighter specifications: ±2 mV max input offset voltage vs. ±4 mV for the TLE2071CP, and ±300 µV typical vs. ±470 µV typical. Both share identical bandwidth, slew rate, noise, and package. Choose TLE2071ACP for high-precision DC applications (e.g., calibration equipment); TLE2071CP remains ideal for cost-sensitive, high-speed AC-coupled systems where offset is corrected digitally or via AC coupling.

Can the TLE2071CP operate with single-supply configurations?

While optimized for dual-supply use, the TLE2071CP supports single-supply operation with appropriate biasing: set V– to ground and V+ to +38 V max, then bias inputs within the common-mode range (e.g., VCM = V+/2). Output swing remains asymmetric (e.g., 0 V to ~V+ − 1.5 V), so level-shifting or rail-splitter networks may be needed for true bipolar signal handling in single-supply systems.
