Product details
Overview
TLC27L2CPS from Texas Instruments is a precision dual CMOS operational amplifier optimized for low-power, single-supply operation in sensor signal conditioning and industrial monitoring systems. It delivers 10 mV max input offset voltage (25°C), ultra-low 34 µA typical supply current at 5 V, and rail-to-rail output swing down to the negative rail - enabling accurate amplification in battery-powered field transmitters and smoke detectors.
For engineers reviewing the TLC27L2CPS datasheet, TLC27L2CPS pinout, TLC27L2CPS application, or TLC27L2CPS equivalent, this page provides verified specifications, validated pin functions, real-world use cases in transmitter interfaces, and confirmed alternative options for precision analog front-ends requiring wide temperature stability and sub-100 µW quiescent power.
Technical Context
The TLC27L2CPS uses Texas Instruments' LinCMOS™ silicon-gate process to achieve high input impedance (10¹² Ω), low bias currents (≤60 pA typ), and exceptional offset voltage stability (0.1 µV/month drift). Its common-mode input range extends 0.2 V below ground, supporting true single-supply operation with inputs referenced to GND.
Designed for C-suffix (0°C to 70°C) operation, it supports 3 V to 16 V supply rails and exhibits 85 kHz unity-gain bandwidth, 0.03 V/µs slew rate, and 65–87 dB CMRR - balancing precision, speed, and power efficiency for analog signal chains where thermal drift and supply headroom are critical constraints.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 10 mV max at 25°C - sets baseline DC error in precision gain stages; impacts accuracy of low-level sensor outputs like thermocouples or strain gauges. |
| Supply Current (2 ch) | 34 µA typical at 5 V - enables multi-year battery life in remote transmitters; reduces self-heating in enclosed enclosures. |
| Input Bias Current | 60 pA max at 25°C - minimizes voltage drop across high-impedance sources (e.g., pH electrodes, piezoelectric sensors). |
| Common-Mode Input Range | −0.2 V to 3.5 V at 5 V supply - allows direct interfacing to 0–5 V sensors without level-shifting circuitry. |
| Output Voltage Swing | Within 50 mV of GND and 0.9 V of VDD - supports full-scale ADC utilization in single-supply data acquisition systems. |
| Unity-Gain Bandwidth | 85 kHz at 5 V - sufficient for <10 kHz sensor signals (pressure, temperature, flow) with stable phase margin (34°). |
| CMRR | 65–87 dB - rejects noise from shared power rails or EMI-coupled common-mode interference in industrial wiring. |
Pinout & Package
Package: PS (8-pin SOP), surface-mount, 5.3 mm × 4.4 mm footprint, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1IN+ | Noninverting input, channel 1 | High-impedance node for reference or sensor signal connection; accepts voltages down to −0.2 V. |
| 1IN− | Inverting input, channel 1 | Feedback path entry point; matched to 1IN+ for minimal input offset current error. |
| 1OUT | Output, channel 1 | Capable of sourcing/sinking ±30 mA; swings within 50 mV of GND and 0.9 V of VDD. |
| GND | Ground / negative supply | Reference for both inputs and outputs; common return for all circuitry sharing same supply domain. |
| 2IN+ | Noninverting input, channel 2 | Independent high-Z input for second sensor or signal path; identical specs to 1IN+. |
| 2IN− | Inverting input, channel 2 | Independent feedback node; enables dual-channel instrumentation or differential-to-single-ended conversion. |
| VDD | Positive supply | Accepts 3–16 V; powers both amplifiers; internal ESD protection rated to 2000 V (MIL-STD-883C). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low power consumption | 95 µW typical at 5 V - enables always-on sensing in energy-constrained IoT nodes and portable safety devices. |
| Single-supply operation | Operates from 3 V to 16 V with inputs extending below GND - eliminates need for split supplies in field transmitter designs. |
| High input impedance | 10¹² Ω typical - prevents loading of high-output-impedance sensors (e.g., capacitive humidity, ion-selective electrodes). |
| Latch-up immunity | Designed-in robustness against transient overvoltage events - improves reliability in noisy industrial environments. |
| ESD protection | 2000 V HBM rating per MIL-STD-883C Method 3015.2 - reduces handling sensitivity and field failure risk. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27L2IDR | Same electrical specs, I-suffix (−40°C to +85°C), SOIC-8 package | Extended temperature range suits outdoor or automotive-adjacent industrial enclosures | Select when operating ambient exceeds 70°C or requires wider qualification margin |
| LMV358IDGKR | Lower offset (7 mV max), higher supply current (80 µA), rail-to-rail I/O, same SOIC-8 | Better DC accuracy but consumes >2× power; no extended temp option | Prefer for cost-sensitive, room-temp applications where offset dominates power budget |
Compared with TLC27L2CPS, TLC27L2IDR offers guaranteed performance over −40°C to +85°C - critical for uncontrolled environments - while LMV358IDGKR trades ultra-low power for tighter offset and full rail-to-rail input/output, making it suitable only where battery life is secondary to initial accuracy.

FAQ
What is the maximum operating temperature range for the TLC27L2CPS?
The TLC27L2CPS is characterized for operation from 0°C to 70°C (C-suffix grade). It supports supply voltages from 3 V to 16 V across this range. At 70°C, key parameters such as input offset voltage remain within 12 mV max, and supply current stays ≤42 µA - ensuring reliable performance in commercial-grade industrial enclosures without forced cooling.
Does the TLC27L2CPS support true single-supply operation with inputs referenced to ground?
Yes, the TLC27L2CPS supports true single-supply operation: its common-mode input voltage range extends to −0.2 V at 5 V supply, allowing both inputs to be biased at or slightly below GND. This enables direct connection to grounded sensors (e.g., thermistors, bridge circuits) without level-shifting components - a key enabler for simplified, low-component-count transmitter designs.
What is the typical input bias current of the TLC27L2CPS, and why does it matter?
The TLC27L2CPS has a typical input bias current of 0.6 pA at 25°C, with a maximum of 60 pA. This ultra-low value minimizes voltage error across high-impedance sensor elements (e.g., >1 MΩ pH electrodes or piezoelectric transducers), preserving signal integrity without requiring guard traces or active bias cancellation networks in sensitive analog front-ends.
Can the TLC27L2CPS drive a 1 MΩ load while maintaining specified accuracy?
Yes - the TLC27L2CPS is fully specified with RL = 1 MΩ in its electrical characteristics tables (e.g., input offset voltage, CMRR, and open-loop gain). Its high output impedance and low output current capability (±30 mA) are not limiting at 1 MΩ loads; output swing remains within 50 mV of rails, and large-signal voltage gain stays ≥50 V/mV - ensuring predictable closed-loop behavior in high-impedance buffering and filtering applications.
Is the TLC27L2CPS pin-compatible with other devices in the TLC27Lx family?
Yes - the TLC27L2CPS shares identical 8-pin SOP (PS) pinout and function mapping with all TLC27Lx dual op-amps, including TLC27L2A, TLC27L2B, TLC27L7, and their I/M-suffix variants. This allows direct substitution for offset grade upgrades or temperature range extensions without PCB redesign - provided supply and layout constraints (e.g., decoupling, thermal relief) meet the target variant's requirements.
