Texas Instruments TLC27M2CPSR

Overview

TLC27M2CPSR from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, designed for single-supply operation with rail-to-rail input (extends below negative rail) and output swing to negative rail. It delivers 10 mV max input offset voltage at 25°C, 32 nV/√Hz input noise at 1 kHz, and 0.4 V/µs slew rate at VDD = 5 V - enabling accurate signal conditioning in battery-powered sensor interfaces and portable instrumentation.

For engineers reviewing the TLC27M2CPSR datasheet, TLC27M2CPSR pinout, TLC27M2CPSR application, or TLC27M2CPSR equivalent, this page provides verified electrical specs, package mapping to TSSOP-8, real-world application context for low-voltage analog front-ends, and validated alternative options for design flexibility under temperature and power constraints.

Technical Context

The TLC27M2CPSR implements a silicon-gate LinCMOS process that achieves high input impedance (10¹² Ω typ), ultra-low input bias current (0.6 pA typ at 25°C), and latch-up immunity - distinguishing it from bipolar op-amps while matching their speed. Its architecture supports common-mode input voltage down to −0.2 V (at VDD = 5 V) and output swing to GND, enabling true single-supply functionality without level-shifting circuitry.

It operates across 3 V to 16 V supply range (0°C to 70°C), features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2), and exhibits stable phase margin (≥39°) with 20 pF capacitive load - making it suitable for unity-gain-stable configurations in filtering and buffering applications.

FAQ

What is the maximum input offset voltage specification for TLC27M2CPSR at 25°C?

The maximum input offset voltage for TLC27M2CPSR is 10 mV at 25°C, as specified in the Electrical Characteristics table for the C-suffix grade under VDD = 5 V test conditions. This value applies across the full 0°C to 70°C operating range, with worst-case drift of 1.7 µV/°C from 25°C to 70°C. The TLC27M2CPSR maintains this grade consistently due to its LinCMOS trimming process.

Does TLC27M2CPSR support true single-supply operation with inputs referenced to ground?

Yes, TLC27M2CPSR 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 to 3.5 V over full temperature range), allowing direct connection of ground-referenced sensors without external level-shifting circuitry - a key advantage over standard CMOS or bipolar op-amps.

What is the recommended power supply decoupling for TLC27M2CPSR?

Texas Instruments recommends a 0.1 µF ceramic capacitor placed as close as possible (<5 mm) to the VDD (Pin 5) and GND (Pin 4) pins of TLC27M2CPSR. For systems with noisy supplies or multiple op-amps, add a 4.7 µF tantalum or aluminum electrolytic capacitor near the board's main power entry point. Avoid series ferrite beads unless validated for stability with the device's 20 pF load tolerance.

Can TLC27M2CPSR drive a 100 kΩ load while maintaining rail-to-rail output swing?

Yes, TLC27M2CPSR drives a 100 kΩ load while delivering rail-to-rail output swing: at VDD = 5 V and TA = 25°C, VOH is ≥3.2 V and VOL is ≤50 mV (i.e., within 50 mV of GND). This behavior is confirmed across the full operating temperature range and meets the "output voltage range includes negative rail" specification - essential for interfacing with 3.3 V or 5 V ADC references.

Is TLC27M2CPSR pin-compatible with other devices in the TLC27Mx family?

Yes, TLC27M2CPSR is pin-compatible with all TSSOP-8 variants in the TLC27Mx dual op-amp family, including TLC27M2ACPSR, TLC27M2BCPSR, TLC27M7CPSR, and their I- and M-suffix equivalents. All share identical pinout, package dimensions, and thermal pad configuration - enabling drop-in substitution based solely on offset voltage grade and temperature range requirements.
