Texas Instruments TLE2072AMJGB

Overview

TLE2072AMJGB from Texas Instruments is a dual-channel JFET-input operational amplifier optimized for high-voltage, low-noise, and high-speed precision applications. It delivers ±19V supply operation, 10MHz unity-gain bandwidth, 32V/μs slew rate, and 17nV/√Hz input voltage noise at 1kHz - enabling accurate signal conditioning in oscilloscopes, electricity meters, and flight control units.

For engineers reviewing the TLE2072AMJGB datasheet, TLE2072AMJGB pinout, TLE2072AMJGB application, or TLE2072AMJGB equivalent, this device supports rail-to-rail differential input operation, offers Zener-trimmed offset voltage (±3.5mV max at 25°C), and is qualified for −55°C to +125°C extended temperature operation in ceramic DIP packaging.

Technical Context

The TLE2072AMJGB implements a JFET-input stage with on-chip Zener trimming for DC precision, supporting wide common-mode input range (up to ±10.9V at ±15V supplies) and stable unity-gain operation. Its architecture enables high open-loop gain (>90dB), low input bias current (±15pA typ), and robust CMRR (80–98dB) across temperature.

It operates with supply voltages from ±2.25V to ±19V, maintains output swing within 1.5V of rails at 20mA load, and exhibits phase margin of 56°–57° at unity gain - ensuring stability in demanding closed-loop configurations including active filters and precision instrumentation amplifiers.

FAQ

What is the maximum operating temperature range for the TLE2072AMJGB?

The TLE2072AMJGB is specified for operation from −55°C to +125°C ambient temperature, validated per MIL-STD-883 methods. This extended range is enabled by its ceramic DIP (JG) package and internal design - making it suitable for aerospace, defense, and oilfield electronics where thermal extremes are routine. The TLE2072AMJGB maintains all key parameters including offset voltage, CMRR, and bandwidth across this full range.

Does the TLE2072AMJGB support rail-to-rail input operation?

Yes, the TLE2072AMJGB supports rail-to-rail differential input operation: its common-mode input voltage range extends from (V−) −0.8V to (V+) +0.5V at ±15V supplies. This allows direct interfacing with signals that swing beyond traditional op-amp input limits - such as transformer-coupled AC waveforms or outputs from other rail-swinging stages - without external level-shifting circuitry. The TLE2072AMJGB achieves this via JFET input transistors and proprietary input stage biasing.

What is the purpose of Pins 1 and 5 on the TLE2072AMJGB?

Pins 1 and 5 on the TLE2072AMJGB are dedicated offset null terminals for Channel 1 and Channel 2 respectively. They connect to opposite ends of an external 10kΩ potentiometer (wiper to V−), allowing manual trimming of input offset voltage to ≤±100µV. This feature is unique to the 'M' and 'AM' variants and is essential for applications demanding highest DC precision - such as calibrated test equipment and metrology-grade instrumentation - where factory-trimmed offset alone is insufficient.

How does the TLE2072AMJGB compare to the standard TLE2072 in terms of performance?

The TLE2072AMJGB improves upon the base TLE2072 with tighter offset voltage (±3.5mV vs. ±6mV max), extended temperature rating (−55°C to +125°C vs. −40°C to +85°C), and ceramic DIP (JG) packaging for hermetic reliability. It retains identical AC specs - 10.6MHz bandwidth, 32V/μs slew rate, and 17nV/√Hz noise - but adds Zener trimming and offset null pins. The TLE2072AMJGB is functionally compatible with TLE2072 circuits but requires attention to pin 1/5 connections for optimal DC performance.

Can the TLE2072AMJGB drive a 600Ω load at full output swing?

Yes, the TLE2072AMJGB can drive a 600Ω load while maintaining full output swing: at ±15V supplies and 25°C, it delivers ±13.5V into 2mA (i.e., ±12V into 600Ω) with <0.0032% THD+N at 1kHz. Its output stage is rated for ±65mA short-circuit current and exhibits low open-loop output impedance (80Ω at 1MHz), ensuring stable operation into reactive or capacitive loads when properly compensated. The TLE2072AMJGB remains unity-gain stable with 25pF capacitive load.
