TL082CDRG4

Instrumentation, Op Amps, Buffer Amps Overview

The TL082CDRG4 is a dual JFET-input operational amplifier manufactured by Texas Instruments. It features a voltage-feedback architecture housed in a 14-pin SOIC package, although the device itself contains two channels. Key electrical specifications include a gain-bandwidth product of 3 MHz and a slew rate of 13 V/µs. The input bias current is typically 400 pA, with a maximum input offset voltage of 15 mV. It operates on a single supply ranging from 7 V to 30 V or dual supplies from ±3.5 V to ±15 V. The common-mode rejection ratio is 86 dB, and it delivers an output current of 10 mA per channel.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'RG4' against the manufacturer's official datasheet to confirm tape-and-reel packaging and RoHS compliance status. Ensure the ordering part number matches the exact pinout and electrical tolerances required for the design. Cross-reference with the latest Texas Instruments documentation to avoid obsolete revisions.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual-channel JFET-input op-amp is required for applications needing high input impedance. Compare the 3 MHz bandwidth and 13 V/µs slew rate against system requirements. Consider the 15 mV max offset voltage for precision needs. Verify that the SOIC-8 package fits the PCB layout constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the TL08x family of JFET-input operational amplifiers from Texas Instruments. It is functionally similar to the TL082CD but differs in packaging format (reel vs. tube) and potentially specific manufacturing lot codes. The family is known for BiFET technology combining JFET inputs with bipolar outputs.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes include TL082CDR and TL082CDE4. Verify pin compatibility and electrical parameter equivalence before substitution.
