Texas Instruments TLE2071IP

Overview

TLE2071IP from Texas Instruments is a single-channel JFET-input operational amplifier optimized for high-voltage, low-noise, 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 flight control units.

For engineers reviewing the TLE2071IP datasheet, TLE2071IP pinout, TLE2071IP application, or TLE2071IP equivalent, this device is selected where rail-to-rail input operation, wide dynamic range (±19 V), and low 1/f noise are critical - especially in industrial instrumentation and high-fidelity analog front-ends requiring stable DC offset and AC performance across −40°C to +85°C.

Technical Context

The TLE2071IP uses Excalibur JFET-input architecture with on-chip Zener trimming for low offset voltage (max 4 mV over temperature) and ultra-low input bias current. Its differential inputs operate up to the supply rails, supporting wide common-mode range (−10.8 V to +15 V at ±15 V supplies).

It features unity-gain stability, 56° phase margin, and 300 kHz maximum output-swing bandwidth under 25 pF load - making it suitable for closed-loop configurations without external compensation in data acquisition and active filtering.

FAQ

What is the maximum supply voltage rating for the TLE2071IP?

The TLE2071IP supports a total supply voltage range of ±2.25 V to ±19 V, meaning the absolute maximum difference between VCC+ and VCC– is 38 V. This allows operation in high-voltage industrial systems such as energy metering front-ends and motor drive current sensing where ±15 V rails are standard. Operation beyond ±19 V violates absolute maximum ratings and risks permanent damage to the TLE2071IP.

Does the TLE2071IP require external offset nulling in precision applications?

Yes - the TLE2071IP provides dedicated offset null pins (1 and 5) for connection to a 10-kΩ potentiometer to trim input offset voltage down to near-zero. While its typical VIO is ±300 µV and max is 4 mV over temperature, applications demanding sub-100 µV DC accuracy (e.g., high-resolution DMMs) require this external nulling. The TLE2071IP's internal Zener trimming sets baseline accuracy but does not eliminate the need for fine adjustment in metrology-grade designs.

What is the common-mode input voltage range of the TLE2071IP at ±15 V supplies?

At ±15 V supplies, the TLE2071IP supports a common-mode input voltage range of −10.8 V to +15 V - extending to within 0.8 V of the negative rail and rail-to-rail on the positive side. This rail-to-rail input capability enables direct interfacing with grounded sensors and unbuffered DAC outputs without level-shifting circuitry, a key advantage over many bipolar-input op-amps in the TLE2071IP's target applications.

Is the TLE2071IP unity-gain stable, and what is its phase margin?

Yes, the TLE2071IP is unity-gain stable with a measured phase margin of 56° at unity gain under standard test conditions (10 mV input, 25 pF load, 2 kΩ load). This ensures stable closed-loop operation without external compensation in buffer, inverter, or follower configurations - critical for reliable performance in oscilloscope vertical amplifiers and active filter stages where instability would manifest as ringing or oscillation.

How does the TLE2071IP's input bias current compare to other JFET-input op-amps, and why does it matter?

The TLE2071IP specifies ±15 pA typical input bias current at 25°C - matching industry-leading JFET-input devices like the OPA140. This ultra-low value prevents voltage errors across high-impedance sources (e.g., >1 MΩ sensor bridges or photodiode transimpedance feedback resistors), preserving signal fidelity in precision measurement. In contrast, bipolar-input op-amps often draw >100 nA, introducing significant offset errors in the same circuits - making the TLE2071IP essential for high-impedance signal chains.
