Texas Instruments TLC25L2BCP

Overview

TLC25L2BCP from Texas Instruments is a LinCMOS™ dual operational amplifier optimized for ultra-low-power, single-supply operation down to 1.4 V, featuring 2-mV maximum input offset voltage (VIO), 20–46 µA total supply current at 5 V, and rail-to-rail common-mode input range extending to the negative rail. It serves as a precision analog front-end gain stage or sensor signal conditioner in battery-powered instrumentation.

For engineers reviewing the TLC25L2BCP datasheet, TLC25L2BCP pinout, TLC25L2BCP application, or TLC25L2BCP equivalent, key selection criteria include its guaranteed 2-mV VIO grade, sub-50-µA quiescent current, LinCMOS™ input impedance >10¹² Ω, and stable unity-gain operation across 1.4–16 V supply range.

Technical Context

The TLC25L2BCP implements a silicon-gate LinCMOS™ process architecture that delivers extremely low input bias currents (≤60 pA typ) and near-zero input offset drift (1 µV/°C max), enabling high-impedance transducer interfacing without passive compensation networks. Its internal ESD protection meets MIL-STD-883C, Method 3015.1 (2000 V).

Unlike bipolar op-amps, it achieves true single-supply functionality with common-mode input voltage spanning from VDD–/GND to within 0.2 V of VDD, while maintaining stable phase margin (>30°) and unity-gain bandwidth up to 110 MHz at VDD = 10 V with RL = 1 MΩ.

FAQ

What is the maximum input offset voltage specification for the TLC25L2BCP?

The TLC25L2BCP has a guaranteed maximum input offset voltage (VIO) of 2 mV at 25°C and 3 mV across the full 0°C to 70°C operating temperature range. This B-grade specification is confirmed in the "Electrical Characteristics" tables for VDD = 5 V and VDD = 10 V under TLC25L2BC test conditions, making it suitable for applications demanding tighter DC accuracy than standard C-grade variants.

Does the TLC25L2BCP support true single-supply operation with inputs referenced to ground?

Yes, the TLC25L2BCP supports true single-supply operation with its common-mode input voltage range extending to VDD–/GND (the negative rail). At VDD = 5 V, the specified VICR is –0.2 V to 3.5 V over temperature, allowing ground-referenced sensor signals to be directly applied to either input without level shifting-confirmed in the "Recommended Operating Conditions" and "Electrical Characteristics" sections of the datasheet.

What is the typical supply current consumption of the TLC25L2BCP at 5 V?

The TLC25L2BCP draws a typical total supply current (IDD) of 20 µA at VDD = 5 V, TA = 25°C, with no load and VIC = 2.5 V. The maximum is 42 µA across 0°C to 70°C, as documented in the "Electrical Characteristics at VDD = 5 V" table for TLC25L2BC. This ultra-low quiescent current enables multi-year operation on primary batteries.

Is the TLC25L2BCP pin-compatible with other devices in the TLC25x2 family?

Yes, the TLC25L2BCP is pin-compatible with all members of the TLC25x2 dual op-amp family in the 8-pin plastic DIP (P) package-including TLC252CP, TLC25L2CP, and TLC25M2CP-as verified by the shared pinout diagram labeled "D, P, OR PW PACKAGE (TOP VIEW)" and identical terminal numbering across device variants in the datasheet.

What is the unity-gain bandwidth of the TLC25L2BCP under typical conditions?

The TLC25L2BCP achieves a minimum unity-gain bandwidth (B1) of 85 MHz at VDD = 5 V, TA = 25°C, RL = 1 MΩ, and CL = 20 pF, as specified in the "Operating Characteristics, VDD = 5 V" table for TLC25L2BC. At VDD = 10 V, this increases to 110 MHz minimum, supporting high-frequency active filtering and wideband sensor signal conditioning.
