Product details
Overview
TLC27M9IDR from Texas Instruments is a precision quad operational amplifier featuring ±300 µV max input offset voltage at 25°C, low 0.6 µV/°C drift, 32 nV/√Hz input noise at 1 kHz, rail-to-rail output swing to negative rail, and 6 TΩ typical input impedance. It operates from 4 V to 16 V over −40°C to +85°C and targets high-accuracy analog signal conditioning in multiplexed data acquisition and test equipment.
For engineers reviewing the TLC27M9IDR datasheet, TLC27M9IDR pinout, TLC27M9IDR application, or TLC27M9IDR equivalent, this page delivers verified specifications, SOIC-14 package details, real-world use cases in motor control and PLC analog I/O, and validated alternative options for design continuity and sourcing flexibility.
Technical Context
The TLC27M9IDR implements LinCMOS™ process technology to achieve ultra-low input bias current (±10 pA typ at 25°C) and high DC precision while maintaining CMOS-level power efficiency. Its architecture supports single-supply operation with common-mode input range extending to −0.2 V below ground and output swing to the negative rail.
It delivers 1.1 MHz unity-gain bandwidth and 0.5 V/µs slew rate at 5 V supply, enabling stable closed-loop performance in precision instrumentation amplifiers, sensor front-ends, and analog filter stages where offset stability and noise floor are critical.

FAQ
What is the maximum input offset voltage specification for the TLC27M9IDR at 25°C?
The TLC27M9IDR has a maximum input offset voltage of ±300 µV at 25°C, as specified in the Electrical Characteristics table for the I-grade (−40°C to +85°C) version. This trimmed offset enables high-accuracy DC-coupled signal chains without external calibration in the TLC27M9IDR design.
Does the TLC27M9IDR support true single-supply operation with output swing to ground?
Yes, the TLC27M9IDR supports true single-supply operation: its output voltage range includes the negative rail (GND), and the common-mode input voltage extends to −0.2 V below GND. This allows the TLC27M9IDR to operate with 0 V as the lower supply rail while delivering full-scale output down to 0 V.
What is the typical input bias current of the TLC27M9IDR at 25°C?
The typical input bias current of the TLC27M9IDR is ±10 pA at 25°C, with a maximum of ±60 pA over the full −40°C to +85°C temperature range. This ultra-low bias current, enabled by LinCMOS™ technology, makes the TLC27M9IDR ideal for interfacing with high-impedance sensors and passive networks.
Which package type is used for the TLC27M9IDR, and what are its dimensions?
The TLC27M9IDR uses the SOIC-14 (D) package, measuring 8.65 mm × 3.9 mm (body size). It is supplied in tape-and-reel format, indicated by the "R" suffix in the part number, and is compatible with standard surface-mount assembly processes for the TLC27M9IDR.
Can the TLC27M9IDR be used in applications requiring operation down to −40°C?
Yes, the TLC27M9IDR is rated for operation from −40°C to +85°C (I-grade), with all key parameters-including offset voltage, drift, noise, and supply current-fully characterized across this range. The TLC27M9IDR is therefore qualified for industrial, automotive under-hood, and outdoor instrumentation environments.
