Product details
Overview
TLE2072MJGB from Texas Instruments is a dual-channel JFET-input operational amplifier optimized for high-voltage, low-noise, high-speed precision applications. It delivers ±19V supply rails, 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 TLE2072MJGB datasheet, TLE2072MJGB pinout, TLE2072MJGB application, or TLE2072MJGB equivalent, this device supports rail-to-rail differential input operation, wide common-mode range (±10.9V at ±15V supplies), and stable unity-gain performance - critical for data acquisition front-ends and high-fidelity analog measurement systems.
Technical Context
The TLE2072MJGB uses JFET-input transistors with on-chip Zener trimming for low offset voltage and ultra-low input bias current (±15pA typ). Its architecture enables operation across ±2.25V to ±19V supplies while maintaining DC precision and AC performance.
It features a fully compensated internal design for unity-gain stability, 56° phase margin, and low output impedance (80Ω typ at 1MHz), supporting direct driving of capacitive loads up to 25pF without oscillation in high-speed closed-loop configurations.
Key Specifications

FAQ
What is the maximum supply voltage for the TLE2072MJGB?
The TLE2072MJGB supports a total supply voltage of up to 38V, meaning ±19V operation is its absolute maximum rated condition. Operation beyond this risks permanent damage. The device is characterized and guaranteed across ±2.25V to ±19V, with all key parameters (bandwidth, slew rate, noise) validated at ±15V and ±5V per the official TI datasheet SLOS181D.
Does the TLE2072MJGB support rail-to-rail input operation?
Yes, the TLE2072MJGB allows differential input voltages up to the supply rails - specifically, its common-mode input range extends to (VCC–) – 0.5V and (VCC+) + 0.5V. At ±15V supplies, this means inputs can swing from −10.9V to +15V, enabling direct interfacing with signals referenced near either rail without external level-shifting circuitry.
What is the input bias current specification for the TLE2072MJGB?
The TLE2072MJGB has a typical input bias current of ±15pA at 25°C, with a maximum of ±60nA over its full −55°C to +125°C operating range. This ultra-low bias current is enabled by its JFET-input architecture and makes it suitable for high-impedance sensor interfaces, such as photodiode transimpedance amplifiers or high-value resistor networks in precision metering.
Is the TLE2072MJGB unity-gain stable?
Yes, the TLE2072MJGB is internally compensated for unity-gain stability. It achieves 56° phase margin at unity gain with a 25pF capacitive load and 2kΩ load resistance, as verified in the TI datasheet's operating characteristics section. No external compensation components are required, simplifying design in gain-of-one buffers and active filters.
What package type does the TLE2072MJGB use, and what are its key mechanical properties?
The TLE2072MJGB uses a ceramic dual-in-line package (CDIP-8), designated JG in TI's ordering nomenclature. Its body measures 9.58mm × 7.62mm, features a hermetic seal, and is qualified for operation from −55°C to +125°C. The package supports lead-free soldering with a 300°C peak reflow profile for 60 seconds, per MIL-STD-883.
