Texas Instruments TLC25M2CP

Overview

TLC25M2CP from Texas Instruments is a LinCMOS™ dual operational amplifier optimized for low-power, single-supply operation across 1.4 V to 16 V. It delivers 2-mV max input offset voltage (B-grade), 0.40 V/µs slew rate at 5 V, 525 kHz unity-gain bandwidth, and rail-to-rail common-mode input range extending to the negative rail - enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.

For engineers reviewing the TLC25M2CP datasheet, TLC25M2CP pinout, TLC25M2CP application, or TLC25M2CP equivalent, key selection criteria include its ultra-low 210–560 µA supply current (dual amp), 32 nV/√Hz input noise at 1 kHz, and compatibility with high-impedance transducer sources requiring sub-µA bias currents and stable DC accuracy over 0°C to 70°C.

Technical Context

The TLC25M2CP employs Texas Instruments' silicon-gate LinCMOS™ process, delivering extremely high input impedance (>10¹² Ω) and femtoamp-level input bias currents (typ. 0.7 pA at 25°C). Its architecture supports true single-supply operation with common-mode input range including ground, making it suitable for direct interfacing with resistive sensors and thermistors without level-shifting circuitry.

It features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.1), unity-gain stability, and low-voltage operation down to 1.4 V - distinguishing it from bipolar op-amps that require higher supply headroom and exhibit higher quiescent current.

FAQ

What is the maximum input offset voltage specification for the TLC25M2CP?

The TLC25M2CP is the B-grade variant of the TLC25M2 series and is specified for a maximum input offset voltage of 2 mV at 25°C and 3 mV across the full 0°C to 70°C operating temperature range. This value is confirmed in the "electrical characteristics" tables for VDD = 5 V and VDD = 10 V under the TLC25M2BC column, and applies specifically to the CP (plastic DIP) package variant of the TLC25M2CP.

Does the TLC25M2CP support true single-supply operation with inputs at ground potential?

Yes, the TLC25M2CP supports true single-supply operation with its common-mode input voltage range extending to VDD–/GND (i.e., 0 V) at all supply voltages from 1.4 V to 16 V. This is explicitly stated in the device description and verified in the VICR specifications: at VDD = 5 V, the range is –0.2 V to 3.5 V, confirming inclusion of ground. This enables direct interfacing with grounded sensors without level-shifting circuitry in the TLC25M2CP application.

What is the typical supply current for the TLC25M2CP at 5 V and room temperature?

The typical supply current for the TLC25M2CP (dual amplifier) is 250 µA at VDD = 5 V and TA = 25°C, with a maximum of 560 µA across 0°C to 70°C. This value is taken directly from the "electrical characteristics" table on page 12 of the datasheet under the TLC25M2C column for IDD, and reflects the low-power advantage of the LinCMOS™ process used in the TLC25M2CP design.

Is the TLC25M2CP unity-gain stable, and what is its phase margin at 5 V?

Yes, the TLC25M2CP is unity-gain stable. At VDD = 5 V and TA = 25°C, its phase margin is 40°, as measured under unity-gain conditions with CL = 20 pF and RL = 100 kΩ (page 14, operating characteristics). This margin ensures stable closed-loop operation in standard non-inverting and inverting configurations without external compensation - a key reliability feature of the TLC25M2CP.

What package type and pin count does the TLC25M2CP use?

The TLC25M2CP uses an 8-pin Plastic Dual In-line Package (PDIP), commonly referred to as the "P" package in TI documentation. Its pinout matches the industry-standard SOIC-8 and TSSOP-8 variants (e.g., TLC25M2CD, TLC25M2CPW), with pins 1–4 assigned to Amp A and pins 5–8 to power and Amp B - fully documented in the top-view diagram on page 1 of the TLC25M2CP datasheet.
