Texas Instruments TLC25L4ACN

Overview

TLC25L4ACN from Texas Instruments is a LinCMOS™ quad operational amplifier optimized for ultra-low-power, single-supply operation down to 1.4 V, featuring 5-mV maximum input offset voltage (VIO), 40 µA typical supply current per amplifier at 5 V, and rail-to-rail common-mode input range extending to the negative rail. It targets battery-powered sensor interfaces, portable medical devices, and energy-harvesting signal conditioning circuits where low quiescent current and true single-supply functionality are critical.

For engineers reviewing the TLC25L4ACN datasheet, TLC25L4ACN pinout, TLC25L4ACN application, or TLC25L4ACN equivalent, key selection considerations include its 5-mV VIO grade, 1-MΩ load-compatible output drive, 70 nV/√Hz input noise at 1 kHz, and compatibility with 0°C to 70°C commercial temperature range designs requiring stable DC precision under micro-power constraints.

Technical Context

The TLC25L4ACN implements a silicon-gate LinCMOS™ process enabling picoampere-level input bias and offset currents (1 pA typ), high open-loop gain (>50 V/mV at 5 V), and intrinsic ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.1). Its architecture supports unity-gain stability and operates across 1.4–16 V supply rails without phase reversal.

Unlike bipolar op-amps, it delivers true single-supply capability via input common-mode range inclusive of VDD–/GND and output swing limited only by load-dependent saturation-enabling direct interfacing with transducers, resistive bridges, and low-voltage ADCs without level-shifting circuitry.

FAQ

What is the maximum supply voltage rating for the TLC25L4ACN?

The TLC25L4ACN has an absolute maximum supply voltage of 18 V, but its recommended operating range is 1.4 V to 16 V. Operating above 16 V risks exceeding safe dissipation limits, especially at elevated ambient temperatures, and may degrade long-term reliability. Always observe derating curves in the datasheet's Dissipation Rating Table for the N-package.

Does the TLC25L4ACN support rail-to-rail output swing?

No-the TLC25L4ACN does not provide rail-to-rail output swing. Its output voltage swing is load-dependent and typically reaches within ~0.5 V of VDD and ~50 mV above VDD–/GND under light loads (e.g., RL ≥ 1 MΩ). At heavier loads (e.g., RL = 10 kΩ), swing degradation increases significantly; consult Figure 1 in the SLOS003G datasheet for exact VOH/VOL vs. load curves.

Can the TLC25L4ACN be used with a single 1.5-V alkaline battery?

Yes-the TLC25L4ACN is fully specified down to 1.4 V supply, making it compatible with fresh 1.5-V alkaline cells. At 1.5 V, it maintains functional operation with reduced slew rate (~0.001 V/µs) and bandwidth, but retains critical DC parameters including input offset voltage and bias current. System designers should verify loop stability and settling time under actual load conditions.

What is the input common-mode voltage range for the TLC25L4ACN?

The TLC25L4ACN features a true single-supply input stage with common-mode voltage range extending from VDD–/GND (0 V) to (VDD – 0.2 V) at 5 V supply, and similarly to (VDD – 0.3 V) at higher supplies. This allows direct connection of grounded sensors (e.g., thermocouples, resistive bridges) without external level-shifting circuitry-a key enabler for simplified, low-component-count analog front-ends.

How does the TLC25L4ACN differ from the TLC254ACN?

The TLC25L4ACN is the low-bias variant (40 µA/amplifier), while the TLC254ACN is the high-bias variant (4 mA/amplifier). Both share identical 5-mV VIO grading and pinout, but the TLC25L4ACN trades bandwidth (85 kHz vs. 1.7 MHz) and slew rate (0.03 V/µs vs. 2.9 V/µs) for 100× lower supply current-making it ideal for always-on, battery-limited applications where speed is secondary to energy efficiency.
