Texas Instruments TLC25L2ACD

Overview

TLC25L2ACD from Texas Instruments is a LinCMOS™ dual operational amplifier optimized for ultra-low-power, single-supply operation down to 1.4 V, with 5-mV maximum input offset voltage (VIO), 20–34 µA typical supply current (IDD) at 5 V, 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 TLC25L2ACD datasheet, TLC25L2ACD pinout, TLC25L2ACD application, or TLC25L2ACD equivalent, this device is selected for low-voltage analog front-ends where input bias current <60 pA, input offset drift ≤1.1 µV/°C, and stable unity-gain operation are required - especially in energy-constrained systems operating from coin cells or solar harvesters.

Technical Context

The TLC25L2ACD implements a silicon-gate LinCMOS™ process architecture, delivering extremely high input impedance (>10¹² Ω) and sub-60-pA input bias currents across 0°C to 70°C. Its input stage supports true single-supply operation with common-mode voltage range including ground, eliminating level-shifting circuitry in sensor amplification stages.

It features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.1), unity-gain stability with 85–100 MHz unity-gain bandwidth (B1) at 5 V, and phase margin ≥34° under 20-pF capacitive load - ensuring robust performance in active filters and transducer interface circuits without external compensation.

FAQ

What is the maximum input offset voltage specification for TLC25L2ACD?

The TLC25L2ACD has a maximum input offset voltage (VIO) of 5 mV at 25°C and across the full 0°C to 70°C operating range, as specified in the "Available Options" table and confirmed in electrical characteristics tables for VDD = 5 V and 10 V. This graded VIO is achieved via factory selection and is guaranteed for all units shipped as TLC25L2ACD.

Does TLC25L2ACD support true single-supply operation with input signals at ground potential?

Yes, the TLC25L2ACD supports true single-supply operation with its common-mode input voltage range (VICR) extending to VDD–/GND. At VDD = 5 V, VICR spans –0.2 V to 3.5 V (full temperature range), allowing direct connection of ground-referenced sensors such as thermocouples or resistive bridges without level-shifting circuitry.

What is the typical supply current for TLC25L2ACD at 1.4 V supply voltage?

At VDD = 1.4 V, the TLC25L2ACD draws 25–34 µA typical supply current (IDD) for both amplifiers combined, as documented in the "electrical characteristics at specified free-air temperature, VDD = 1.4 V" table. This ultra-low IDD enables multi-year operation from primary lithium or alkaline cells in always-on monitoring applications.

Is TLC25L2ACD unity-gain stable, and what is its phase margin under load?

Yes, the TLC25L2ACD is unity-gain stable. At VDD = 5 V and TA = 25°C with CL = 20 pF and RL = 1 MΩ, its phase margin (φm) is 34°, rising to 36° at 0°C and remaining ≥30° at 70°C - confirming unconditional stability in unity-gain buffer and active filter configurations without external compensation.

Can TLC25L2ACD be used in place of TLC25L2CD without circuit modification?

Yes, the TLC25L2ACD is pin-compatible and functionally identical to the TLC25L2CD except for the tighter 5-mV VIO grade. All electrical, thermal, and packaging specifications match exactly - meaning PCB layout, external components, and firmware require no changes when upgrading from TLC25L2CD to TLC25L2ACD for improved DC accuracy.
