Texas Instruments TLC27L2CPWR

Overview

TLC27L2CPWR from Texas Instruments is a precision dual CMOS operational amplifier in TSSOP-8 package, featuring 10 mV max input offset voltage (25°C), ultra-low 34 µA typical supply current per amplifier at 5 V, and rail-to-rail output swing down to the negative rail. It operates from 3 V to 16 V over 0°C to 70°C and supports single-supply sensor signal conditioning in battery-powered field transmitters.

For engineers reviewing the TLC27L2CPWR datasheet, TLC27L2CPWR pinout, TLC27L2CPWR application, or TLC27L2CPWR equivalent, key selection criteria include input offset voltage stability (0.1 µV/month drift), common-mode input range extending below ground, and LinCMOS™ process-based latch-up immunity for robust analog front-end design.

Technical Context

The TLC27L2CPWR uses Texas Instruments' silicon-gate LinCMOS™ process, delivering high input impedance (10¹² Ω typical) and femtoamp-level bias currents (0.6 pA typical at 25°C). Its architecture enables stable operation with capacitive loads up to 20 pF while maintaining ≥34° phase margin at unity gain.

It supports single-supply operation with common-mode input voltage ranging from –0.2 V to 3.5 V (at VDD = 5 V), and output voltage swing from near GND to within 0.9 V of VDD - enabling direct interfacing with low-voltage ADCs and microcontrollers without level-shifting.

FAQ

What is the maximum operating temperature range for the TLC27L2CPWR?

The TLC27L2CPWR is rated for operation from 0°C to 70°C (C-suffix grade). It supports supply voltages from 3 V to 16 V across this range, with guaranteed specifications including 10 mV max input offset voltage and 34 µA typical supply current at 25°C. The device is not qualified for extended industrial (–40°C to +85°C) or military (–55°C to +125°C) temperature ranges.

Does the TLC27L2CPWR support true single-supply operation with inputs referenced to ground?

Yes, the TLC27L2CPWR supports true single-supply operation with its common-mode input voltage range extending to –0.2 V (below GND) at VDD = 5 V. This allows direct connection of grounded sensors such as thermocouples or resistive bridges without level-shifting circuitry - a key advantage over standard rail-to-rail input op-amps that require biasing above ground.

What is the output voltage swing capability of the TLC27L2CPWR at 5 V supply?

At VDD = 5 V, the TLC27L2CPWR delivers an output voltage swing from within 50 mV of GND (low-level) to within 0.9 V of VDD (high-level), i.e., approximately 0.05 V to 4.1 V. This rail-swing behavior enables full utilization of 5 V ADC reference ranges and eliminates need for external pull-up/pull-down components in most sensor interface designs.

How does the input offset voltage drift specification impact long-term system calibration?

The TLC27L2CPWR specifies input offset voltage drift of typically 0.1 µV/month, including the first 30 days. Over a 5-year deployment, this accumulates to <6 µV drift - negligible compared to its 10 mV max initial offset. This stability reduces or eliminates need for periodic field recalibration in applications like pressure or temperature transmitters where maintenance access is limited.

Is the TLC27L2CPWR pin-compatible with other packages in the TLC27L2x family?

Yes, the TLC27L2CPWR (TSSOP-8) shares identical pinout with the TLC27L2CDR (SOIC-8), TLC27L2CP (PDIP-8), and TLC27L2CPS (SOP-8) variants. All use the same 8-pin configuration: OUT1, IN–1, IN+1, GND, IN+2, IN–2, OUT2, VDD. This allows direct footprint substitution between packages without schematic or layout changes.
