Texas Instruments TLC27M2AIDR

Overview

TLC27M2AIDR from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, featuring 5 mV max input offset voltage at 25°C, −40°C to 85°C operating range, 32 nV/√Hz input noise at 1 kHz, and rail-to-rail output swing down to the negative rail. It serves as a low-power, high-impedance signal conditioning IC in sensor front-ends and battery-powered instrumentation.

For engineers reviewing the TLC27M2AIDR datasheet, TLC27M2AIDR pinout, TLC27M2AIDR application, or TLC27M2AIDR equivalent, this page delivers verified specifications, package mapping, thermal performance data, and real-world design context for analog signal chain selection in industrial and portable systems.

Technical Context

The TLC27M2AIDR implements a silicon-gate LinCMOS process enabling stable offset voltage (5 mV max), ultra-low input bias current (0.6 pA typ), and high common-mode rejection (91 dB min). Its architecture supports single-supply operation with input voltage range extending below ground and output swing to V−.

It delivers 525 kHz unity-gain bandwidth and 0.4 V/µs slew rate at VDD = 5 V, optimized for transducer interfacing and active filtering where precision, low power (210 µA per amplifier), and wide supply range (4–16 V) are critical.

FAQ

What is the maximum input offset voltage specification for TLC27M2AIDR over its full operating temperature range?

The TLC27M2AIDR has a maximum input offset voltage of 7 mV across its full −40°C to +85°C operating range, as specified in the "electrical characteristics" table for the I-suffix grade under VDD = 5 V and full temperature conditions. At 25°C only, the limit is tighter: 5 mV max.

Does TLC27M2AIDR support true single-supply operation with inputs referenced to ground?

Yes, the TLC27M2AIDR supports true single-supply operation: its common-mode input voltage range extends to −0.2 V below GND at 25°C (and to 0 V at −55°C), and its output swings fully to the negative rail. This allows ground-referenced sensor signals to be amplified directly without level-shifting circuitry.

What is the typical supply current consumption of TLC27M2AIDR at 5 V and 25°C?

The typical supply current for TLC27M2AIDR is 210 µA per amplifier (420 µA total for both channels) at VDD = 5 V and TA = 25°C, as measured under no-load conditions with VO = 2.5 V and VIC = 2.5 V. This corresponds to ~2.1 mW total power dissipation.

Is TLC27M2AIDR pin-compatible with other devices in the TLC27Mx family?

Yes, TLC27M2AIDR is pin-compatible with all SOIC-8 variants in the TLC27M2/TLC27M7 family, including TLC27M2CDR, TLC27M2BIDR, and TLC27M7IDR. All share identical D-package pinout, terminal functions, and footprint - only offset voltage grade and temperature rating differ.

What packaging and reel specifications apply to TLC27M2AIDR?

TLC27M2AIDR is supplied in an SOIC-8 (D) package with tape-and-reel packaging per TI standard: 2500 units per reel, 12 mm tape width, 4 mm pocket pitch, and EIA-481-D compliant orientation. The R suffix explicitly denotes this reel format, confirmed in the "AVAILABLE OPTIONS" table of the datasheet.
