Texas Instruments TLE2071CPE4

Overview

TLE2071CPE4 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 ±15 pA input bias current - enabling accurate signal conditioning in oscilloscopes, electricity meters, and AC drive power stage modules.

For engineers reviewing the TLE2071CPE4 datasheet, TLE2071CPE4 pinout, TLE2071CPE4 application, or TLE2071CPE4 equivalent, this page provides verified electrical characteristics, package-specific terminal functions, real-world use cases, and validated alternative options for industrial analog signal chains requiring rail-to-rail input operation and low 1/f noise.

Technical Context

The TLE2071CPE4 employs a JFET-input stage with on-chip Zener trimming for DC precision, supporting differential inputs up to the supply rails and operating across ±2.25 V to ±19 V supplies. Its wide dynamic range and 10.6 MHz gain-bandwidth product enable stable unity-gain configurations with 56° phase margin.

It achieves low 17 nV/√Hz noise floor at 1 kHz while maintaining 0.3–0.5 mV typical input offset voltage (C-grade), making it suitable for high-resolution data acquisition where thermal drift and broadband noise must be minimized simultaneously.

Key Specifications

FAQ

What is the maximum supply voltage rating for the TLE2071CPE4?

The TLE2071CPE4 supports a maximum supply voltage of ±19 V, as specified in its Absolute Maximum Ratings table. This allows operation in high-dynamic-range industrial systems such as AC drive power stage modules and oscilloscope front-ends without external regulation. Exceeding ±19 V risks permanent damage, and recommended operation remains within ±2.25 V to ±19 V per the datasheet's Recommended Operating Conditions section for the C-suffix grade.

Does the TLE2071CPE4 require external offset nulling in precision applications?

Yes - the TLE2071CPE4 includes dedicated OFFSET N1 (Pin 1) and OFFSET N2 (Pin 5) terminals for external nulling using a 10 kΩ potentiometer. While its typical input offset voltage is 0.3–0.5 mV, applications demanding <50 μV offset - such as high-resolution digital multimeters - benefit from this adjustment. The nulling circuit connects between Pins 1 and 5, with the wiper grounded, enabling calibration during production or field service of the TLE2071CPE4.

How does the TLE2071CPE4 perform in unity-gain stable configurations?

The TLE2071CPE4 is explicitly unity-gain stable, with a measured phase margin of 56° at unity gain and 25°C (CL = 25 pF, RL = 2 kΩ). Its 10.6 MHz gain-bandwidth product and internal compensation ensure stable operation in voltage-follower, active filter, and transimpedance configurations without external compensation components. This stability is confirmed across all operating conditions in the TLE2071C Electrical Characteristics tables, making the TLE2071CPE4 suitable for direct replacement in legacy TL071-based circuits requiring improved speed and noise.

Can the TLE2071CPE4 drive a 600 Ω load effectively?

Yes - the TLE2071CPE4 delivers ±65 mA short-circuit output current and maintains <0.1% THD+N into 600 Ω at 1 kHz (VO = 3 VRMS). Its large-signal differential voltage amplification exceeds 80 dB into 600 Ω, and output swing reaches ±4.5 V at ±20 mA load under ±5 V supplies. These characteristics confirm robust drive capability for legacy test equipment interfaces, audio line drivers, and instrumentation outputs where 600 Ω termination is standard - all while preserving the low-noise advantage of the TLE2071CPE4.

What is the input common-mode voltage range of the TLE2071CPE4?

The TLE2071CPE4 features rail-to-rail input capability: its common-mode input voltage range extends to within 0.9 V of either supply rail (e.g., −10.9 V to +15 V with ±15 V supplies). This allows direct connection of transducers, shunts, or sensor bridges without level-shifting circuitry. The specification is validated across temperature (0°C to 70°C for C-grade) and matches the "amplifier operates with differential inputs up to supply rail" feature stated in the official TI datasheet for the TLE2071CPE4.
