Texas Instruments TL072IPG4

Overview

TL072IPG4 from Texas Instruments is a dual JFET-input operational amplifier optimized for low-noise audio and precision signal conditioning. It delivers 20 V/μs slew rate, 37 nV/√Hz input voltage noise at 1 kHz, ±2.25 V to ±20 V supply range, and operates across –40°C to +125°C - enabling use in pro-audio mixers and battery test equipment where wide common-mode input (including V_CC+) and output short-circuit protection are critical.

For engineers reviewing the TL072IPG4 datasheet, TL072IPG4 pinout, TL072IPG4 application, or TL072IPG4 equivalent, key selection criteria include its FET-input architecture for ultra-low bias current (±1 pA typ), low offset drift (±2 μV/°C), high CMRR (105 dB), and compatibility with single- or dual-supply configurations up to 40 V total.

Technical Context

The TL072IPG4 implements a two-stage JFET-input op-amp topology with internal frequency compensation, delivering stable unity-gain operation and 5.25 MHz gain-bandwidth product. Its input stage uses matched JFET pairs to achieve sub-picoampere bias currents and rail-to-rail common-mode input range extending to V_CC+.

Output stage provides symmetrical sourcing/sinking capability with 210 mV positive and 215 mV negative headroom into 10 kΩ at ±20 V supply, and includes integrated short-circuit protection limiting output current to ±26 mA. EMI rejection ratio of 53 dB at 1 GHz supports robust operation in electrically noisy environments.

Key Specifications

Pinout & Package

FAQ

What is the maximum supply voltage for TL072IPG4?

The TL072IPG4 supports a total supply voltage range of ±2.25 V to ±20 V (4.5 V to 40 V). Absolute maximum ratings specify 36 V for NS/PS packages and TL07xM devices, but TL072IPG4 - as a PDIP-packaged industrial-grade variant - is rated for continuous operation up to 40 V total supply. Exceeding this may cause permanent damage.

Does TL072IPG4 have rail-to-rail input or output capability?

The TL072IPG4 features rail-inclusive common-mode input range - meaning its inputs accept voltages up to V_CC+ - but it does not provide rail-to-rail output swing. Typical output headroom is 210 mV from the positive rail and 215 mV from the negative rail into 10 kΩ at ±20 V supply. For true rail-to-rail operation, consider newer alternatives like the OPA2313.

Can TL072IPG4 operate from a single supply?

Yes, TL072IPG4 can operate from a single supply (e.g., +15 V and GND) because its common-mode input range includes the positive rail (V_CC+). However, the output cannot swing to either rail, so proper biasing of input signals near mid-supply and use of AC-coupling or level-shifting may be required for full dynamic range utilization.

What is the input bias current specification for TL072IPG4?

The TL072IPG4 exhibits an input bias current of ±1 pA (typical) at 25°C, with a maximum of ±120 pA across the full –40°C to +125°C temperature range. This ultra-low value stems from its JFET input stage and makes it ideal for integrating capacitors, photodiode amplifiers, and other high-impedance sensor interfaces where leakage current would otherwise dominate error budgets.

Is TL072IPG4 pin-compatible with other TL072 variants?

Yes, TL072IPG4 shares the standard 8-pin PDIP footprint and pinout with all TL072x variants (e.g., TL072CP, TL072CDR, TL072IDR). Pin functions - including dual amplifier inputs/outputs and dual supply rails - are identical across the family. Differences lie only in temperature grade, packaging, and electrical specifications - not physical or logical connectivity.
