Texas Instruments TLE2082AIP

Overview

TLE2082AIP from Texas Instruments is a dual high-speed JFET-input operational amplifier in an 8-pin PDIP package, delivering 10.6 MHz unity-gain bandwidth, 32 V/μs slew rate, and ±19 V supply capability. It serves as a direct upgrade to TL082 and TL072 in precision analog signal conditioning stages of test equipment and industrial measurement systems.

For engineers reviewing the TLE2082AIP datasheet, TLE2082AIP pinout, TLE2082AIP application, or TLE2082AIP equivalent, this page provides verified electrical specifications, dual-channel pin mapping, temperature-stable DC performance (4 mV max VIO at –40°C to +85°C), and real-world use cases in oscilloscopes, electricity meters, and AC drive modules.

Technical Context

The TLE2082AIP implements a JFET-input differential pair with high-impedance inputs (100 MΩ common-mode, 6 TΩ differential), enabling low input bias current (15–175 nA) and minimal loading on high-impedance sources. Its internal compensation ensures stable unity-gain operation with 56° phase margin at 10.6 MHz.

It supports rail-to-rail output swing within ±1.5 V of rails at 20 mA load and maintains 120 dB crosstalk attenuation between channels - critical for dual-channel instrumentation where channel isolation prevents signal coupling errors.

FAQ

What is the maximum supply voltage rating for the TLE2082AIP?

The TLE2082AIP supports a total supply voltage (VCC+ to VCC–) of up to 38 V, corresponding to ±19 V operation. This allows direct integration into industrial systems using ±15 V or ±18 V rails without external regulation, preserving headroom for high-swing signal conditioning in oscilloscope front-ends and AC drive monitoring circuits. The TLE2082AIP remains fully specified across its entire ±2.25 V to ±19 V range.

Does the TLE2082AIP offer true rail-to-rail output capability?

No, the TLE2082AIP does not provide rail-to-rail output swing. At ±15 V supply and 20 mA load, its output swings from –11.5 V to +11.5 V - a 23 V peak-to-peak range centered on 0 V. This represents a 3.5 V saturation margin per rail, consistent with JFET-input op-amps of this era. For applications requiring closer-to-rail operation, external level-shifting or a modern rail-to-rail output op-amp would be needed, but the TLE2082AIP's 11.5 V swing suffices for most industrial ±10 V signal chains.

How does the TLE2082AIP differ from the standard TLE2082IP?

The TLE2082AIP belongs to the "A" grade variant, featuring tighter input offset voltage specification: 4 mV maximum over –40°C to +85°C versus 7 mV for the standard TLE2082IP. Both share identical pinout, bandwidth (10.6 MHz), slew rate (32 V/μs), and package (PDIP-8). The "A" suffix denotes enhanced DC precision - critical for uncalibrated metering and high-accuracy sensor interfaces where offset drift must be minimized without trimming.

Can the TLE2082AIP replace TL082 devices without circuit modification?

Yes, the TLE2082AIP is explicitly designed as a direct upgrade to TL082 and TL072 op-amps. It uses the same PDIP-8 package, identical pinout (1OUT, 1IN–, 1IN+, VCC–, 2IN+, 2IN–, 2OUT, VCC+), and compatible biasing requirements. No PCB layout changes are needed. Key improvements - including doubled bandwidth (10.6 MHz vs. 4 MHz), lower VIO (4 mV vs. 15 mV), and wider ±19 V supply - deliver immediate performance gains without redesign.

What is the input bias current specification for the TLE2082AIP at 25°C?

At 25°C, the TLE2082AIP exhibits an input bias current of 15–175 nA, as specified in the Electrical Characteristics tables under "IIB". This low bias current stems from its JFET-input architecture and enables accurate amplification of signals from high-impedance sources such as photodiode transimpedance nodes or passive filter networks - a key advantage over bipolar-input op-amps like the LM358, which typically draw >100 nA more bias current.
