Texas Instruments TLC27M2CDR

Overview

TLC27M2CDR from Texas Instruments is a dual precision CMOS operational amplifier with 10 mV maximum input offset voltage at 25°C, rail-to-rail output swing down to the negative rail, and operation from 3 V to 16 V supply across 0°C to 70°C. It delivers 0.40 V/µs slew rate, 32 nV/√Hz input noise at 1 kHz, and 525 kHz unity-gain bandwidth at VDD = 5 V - enabling low-power sensor signal conditioning in battery-powered instrumentation.

For engineers reviewing the TLC27M2CDR datasheet, TLC27M2CDR pinout, TLC27M2CDR application, or TLC27M2CDR equivalent, this device is selected for cost-sensitive analog front-ends requiring single-supply operation, high input impedance (>10¹² Ω), ESD protection (2000 V HBM), and stable DC performance over temperature without bipolar power consumption penalties.

Technical Context

The TLC27M2CDR uses Texas Instruments' LinCMOS silicon-gate process to achieve ultra-low input bias current (0.6 pA typ at 25°C) and exceptional input offset voltage stability (0.1 µV/month drift). Its common-mode input range extends below the negative rail, supporting true single-supply transducer interfacing where ground-referenced signals must be amplified without level-shifting.

Designed for unity-gain stable operation, it features 40° phase margin at 525 kHz (VDD = 5 V), 91 dB CMRR, and 93 dB PSRR - making it suitable for precision DC-coupled amplification in environments with moderate supply ripple or common-mode interference.

FAQ

What is the maximum input offset voltage specification for TLC27M2CDR over temperature?

The TLC27M2CDR has a maximum input offset voltage of 10 mV at 25°C and up to 12 mV across its full operating range of 0°C to 70°C. This value is confirmed in the "Electrical Characteristics" table for the TLC27M2C grade under VDD = 5 V, full temperature range testing conditions. The device does not specify a tighter drift coefficient beyond the guaranteed max, so system-level calibration should accommodate the 12 mV worst case.

Can TLC27M2CDR operate from a 3.3 V supply while maintaining rail-to-rail output swing?

Yes, the TLC27M2CDR is fully specified for 3 V minimum supply and achieves rail-to-rail output swing down to the negative rail (VOL ≤ 50 mV at IOL = 0) even at 3.3 V. The "Recommended Operating Conditions" table confirms VDD = 3 V to 16 V for C-suffix devices, and the "Electrical Characteristics" section lists VOL performance at VDD = 5 V and 10 V - with extrapolation validated by TI's application notes for LinCMOS op-amps operating at 3.3 V.

Does TLC27M2CDR support true single-supply operation with inputs referenced to ground?

Yes, the TLC27M2CDR supports true single-supply operation with inputs referenced to ground: its common-mode input voltage range extends to −0.2 V below GND at VDD = 5 V (and −0.2 V at VDD = 3 V per design characterization), allowing ground-referenced transducer signals to be amplified without external biasing. This is explicitly stated in the "Recommended Operating Conditions" table under VICR.

What is the thermal dissipation limit for TLC27M2CDR in SOIC-8 package at 70°C ambient?

In the SOIC-8 (D) package, the TLC27M2CDR has a power rating of 464 mW at TA = 70°C, derived from the 725 mW rating at 25°C and a derating factor of 5.8 mW/°C. This assumes proper PCB copper area per TI's thermal guidelines; exceeding this limit risks exceeding the absolute maximum junction temperature of 150°C, especially under sustained output loading.

Is TLC27M2CDR pin-compatible with other devices in the TLC27xx family?

Yes, all dual op-amps in the TLC27x2 and TLC27x7 families (e.g., TLC27M7CDR, TLC27L2CDR) share identical SOIC-8 pinouts per the "D, JG, P OR PW PACKAGE (TOP VIEW)" diagram. Pin functions - including dual independent amplifiers, shared VCC and GND - are consistent across grades, enabling drop-in substitution where offset, speed, and supply current requirements align.
