TLC083AIDR

Instrumentation, Op Amps, Buffer Amps Overview

The TLC083AIDR is a dual-channel operational amplifier from Texas Instruments' BiMOS family, designed for wide-bandwidth and high-output-drive applications. It features a gain-bandwidth product of 10 MHz and a typical slew rate of 16 V/µs. The device operates on a single supply voltage ranging from 4.5 V to 16 V or split supplies of ±2.25 V to ±8 V. Key electrical characteristics include an input offset voltage of 1.9 mV (max 1.5 mV for the A-grade), low input bias current of 50 pA, and an equivalent input noise voltage density of 8.5 nV/√Hz at 1 kHz. It provides high output drive capability with sourcing currents up to 57 mA and sinking currents up to 55 mA.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'AIDR' corresponds to the industrial temperature range (-40°C to 125°C) and SOIC-14 surface-mount package. Confirm that the 'A' grade indicates the tighter input offset voltage specifications compared to standard grades. Ensure the 'R' suffix matches the required tape-and-reel packaging format for automated assembly processes.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when upgrading from legacy BiFET amplifiers requiring higher AC performance and single-supply compatibility. The device is suitable for designs needing rail-to-rail-like output swing near the negative rail and high current drive capabilities. Consider the MSOP PowerPAD option if thermal management in smaller footprints is critical.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the TLC08x series, representing the first members of TI's new BiMOS general-purpose operational amplifier family. Developed using a patented LBC3 BiCMOS process, it serves as an upgrade path for users transitioning from dual-supply BiFET systems to single-supply architectures while demanding improved DC and AC performance metrics.

Instrumentation, Op Amps, Buffer Amps FAQ

Does the TLC083AIDR support ground-referenced common-mode input voltages?

Yes, the common-mode input voltage range includes ground (GND) when operating within the specified supply voltage limits.

What is the function of the SHDN pin on the TLC083?

The SHDN pin enables a low-power shutdown mode. Driving this pin below 0.8 V reduces the supply current per channel to approximately 125 µA.
