Texas Instruments TLC27M2CP

Overview

TLC27M2CP from Texas Instruments is a dual precision LinCMOS operational amplifier with 10 mV maximum input offset voltage at 25°C, rail-to-rail output swing (including 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 and battery-powered analog front-ends.

For engineers reviewing the TLC27M2CP datasheet, TLC27M2CP pinout, TLC27M2CP application, or TLC27M2CP equivalent, this page provides verified package mapping (8-pin PDIP), confirmed dual-opamp circuit role, real-world common-mode input range (−0.2 V to 3.5 V at VDD = 5 V), and validated alternatives for cost-sensitive industrial transducer interfaces requiring single-supply operation.

Technical Context

The TLC27M2CP uses silicon-gate LinCMOS process technology to achieve high input impedance (10¹² Ω typ), ultra-low input bias current (0.6 pA typ at 25°C), and inherent latch-up immunity. Its input stage extends below the negative rail, supporting true single-supply operation without level-shifting circuitry.

It features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2) and is characterized for stable performance across temperature with 1.7 µV/°C average offset drift (25°C to 70°C). The device exhibits 91 dB CMRR and 93 dB PSRR at 25°C, making it suitable for precision DC-coupled amplification in noisy environments.

FAQ

What is the maximum input offset voltage specification for TLC27M2CP at 25°C?

The maximum input offset voltage for TLC27M2CP at 25°C is 10 mV, as specified in the "Electrical Characteristics" table under TLC27M2C grade. This value applies across the full operating temperature range (0°C to 70°C) when tested with VO = 1.4 V, RS = 50 Ω, VIC = 0, and RI = 100 kΩ. The TLC27M2CP maintains this 10 mV limit consistently, distinguishing it from tighter grades like TLC27M2ACP (5 mV max).

Does TLC27M2CP support true single-supply operation with inputs referenced to ground?

Yes, TLC27M2CP supports true single-supply operation with inputs referenced to ground. Its common-mode input voltage range extends to −0.2 V at VDD = 5 V (and −0.2 V to 3.5 V across full temperature range), allowing direct connection of grounded-sensor outputs such as Wheatstone bridges. This capability eliminates the need for external level-shifting circuitry and is explicitly enabled by its LinCMOS input stage design.

What is the typical supply current consumption of TLC27M2CP at 25°C and VDD = 5 V?

The typical supply current consumption of TLC27M2CP at 25°C and VDD = 5 V is 210 µA for both amplifiers combined, with a maximum of 560 µA across the full 0°C to 70°C range. This value is measured under no-load conditions with VO = 2.5 V and VIC = 2.5 V. The low IDD enables use in battery-powered systems where average current draw must remain below 1 mA.

Can TLC27M2CP drive capacitive loads up to 100 pF without instability?

TLC27M2CP is characterized for stability with CL = 20 pF (per Figure 1 test setup), and its phase margin remains ≥39° at 70°C with 20 pF load. Driving 100 pF loads is not guaranteed per datasheet; stability degrades beyond 20–30 pF without isolation resistance. For >50 pF loads, TI recommends adding a 100–500 Ω series resistor between output and capacitance - a practice confirmed effective in application note SLOA013B for TLC27Mx family devices.

Is TLC27M2CP pin-compatible with other devices in the TLC27Mx family?

Yes, TLC27M2CP is pin-compatible with all P-package variants in the TLC27Mx family, including TLC27M2ACP, TLC27M2BCP, TLC27M7CP, and TLC27M2IP. All share identical 8-pin PDIP pinout (OUT A, IN− A, IN+ A, GND, IN+ B, IN− B, OUT B, VCC), enabling drop-in replacement within the same temperature grade (C-suffix = 0°C to 70°C). This allows design flexibility to upgrade or downgrade offset voltage grade without PCB revision.
