TLC271MDR

Instrumentation, Op Amps, Buffer Amps Overview

The TLC271MDR is a single-channel operational amplifier from the LinCMOS programmable low-power family, manufactured by Texas Instruments. It utilizes silicon-gate technology to provide high input impedance and stable offset voltage drift. The device features a bias-select pin allowing users to configure performance across three modes: High, Medium, and Low. In High-bias mode, it offers superior AC performance with a typical unity-gain bandwidth of 1.7 MHz and slew rate of 3.6 V/µs at 5V supply. The M-suffix variant supports an extended military temperature range of -55°C to 125°C with a supply voltage range of 5V to 16V. It is housed in an 8-pin Small Outline (D) package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the ordering suffix 'M' corresponds to the specified -55°C to 125°C operating temperature range and the 'DR' suffix indicates the tape-and-reel packaging format. Confirm the specific offset voltage grade required for the application, as the base model designation may imply standard grades unless a sub-suffix like 'B' or 'A' is explicitly included in the full part number.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing for environments requiring wide temperature stability and low power consumption. The bias-select capability allows optimization for either speed or efficiency. Ensure the application benefits from rail-to-rail output swing on the negative side and high input impedance characteristics inherent to CMOS technology.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the TLC271 series of programmable low-power operational amplifiers. It shares architectural similarities with the TLC271C and TLC271I variants but is distinguished by its military-grade temperature rating (-55°C to 125°C). The D package option provides a surface-mount solution suitable for high-density system applications.

Instrumentation, Op Amps, Buffer Amps FAQ

How is the bias-select mode configured?

The bias-select pin can be connected to one of three voltage levels to select High, Medium, or Low bias modes, trading off between power dissipation and AC performance parameters such as slew rate and bandwidth.

What is the common-mode input voltage range?

The common-mode input voltage range extends below the negative rail, allowing for single-supply operation where the input can go down to approximately 0.2V below the positive supply depending on the specific voltage conditions.
