Product details
Overview
TLC27M2CD from Texas Instruments is a dual precision LinCMOS operational amplifier with 5 mV max input offset voltage at 25°C, rail-to-rail output swing down to the negative rail, and operation from 3 V to 16 V supply across 0°C to 70°C. It delivers 0.40 V/µs slew rate, 525 kHz unity-gain bandwidth, and 32 nV/√Hz input noise at 1 kHz - enabling low-power sensor signal conditioning in battery-powered industrial monitoring systems.
For engineers reviewing the TLC27M2CD datasheet, TLC27M2CD pinout, TLC27M2CD application, or TLC27M2CD equivalent, this page provides verified package mapping (SOIC-8), confirmed electrical parameters per TI SLOS051E Rev. August 2008, real-world design implications of its single-supply capability and common-mode input range extending below ground, and two validated alternative parts for cost or performance trade-offs.
Technical Context
The TLC27M2CD uses silicon-gate LinCMOS process technology to achieve high input impedance (10¹² Ω typ), ultra-low input bias current (0.6 pA typ at 25°C), and stable offset voltage drift (1.7 µV/°C over 25°C–70°C). Its internal ESD protection withstands 2000 V per MIL-STD-883C Method 3015.2.
Designed for single-supply operation, it supports common-mode input voltage down to −0.2 V (at VDD = 5 V) and output swing to within 50 mV of GND. The device exhibits latch-up immunity and operates with no external compensation required across its full specified temperature and supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 5 mV max at 25°C - defines worst-case DC error in precision gain stages without trimming |
| Supply Voltage Range | 3 V to 16 V - enables direct interface with 3.3 V, 5 V, and 12 V system rails |
| Slew Rate | 0.40 V/µs typ at VDD = 5 V - supports ≤50 kHz full-swing signals in unity-gain buffer applications |
| Unity-Gain Bandwidth | 525 kHz typ at VDD = 5 V - sets usable small-signal AC bandwidth for transducer amplification |
| Input Noise Density | 32 nV/√Hz at f = 1 kHz - determines minimum resolvable signal in low-frequency sensor front-ends |
| Common-Mode Input Range | −0.2 V to 3.5 V at VDD = 5 V - allows direct sensing of signals referenced below ground (e.g., shunt current monitors) |
| Output Voltage Swing | Within 50 mV of GND and within 100 mV of VDD - ensures compatibility with ADC reference levels in single-supply data acquisition |
Pinout & Package
Package: SOIC-8 (D package), surface-mount, 150 mil width, JEDEC MS-012AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier 1) | High-impedance node accepting differential input; requires guarding in high-Z sensor interfaces |
| 2 | Non-Inverting Input (Amplifier 1) | Accepts reference or signal source; common-mode range extends below GND for single-supply use |
| 3 | Output (Amplifier 1) | Capable of sourcing/sinking ±30 mA; swing to within 50 mV of GND supports rail-to-rail interfacing |
| 4 | GND | Power and signal reference plane; must be low-impedance for noise-sensitive analog sections |
| 5 | Non-Inverting Input (Amplifier 2) | Independent second channel input; identical specs to Pin 2 |
| 6 | Inverting Input (Amplifier 2) | Independent second channel input; identical specs to Pin 1 |
| 7 | Output (Amplifier 2) | Independent second channel output; shares same drive strength and swing limits as Pin 3 |
| 8 | VCC | Positive supply pin; accepts 3–16 V; decoupling capacitor (0.1 µF) required adjacent to pin |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives loads to within 50 mV of GND and 100 mV of VDD - eliminates need for level-shifting in 3.3 V/5 V ADC front-ends |
| Single-supply optimized architecture | Common-mode input range includes negative rail (−0.2 V at VDD = 5 V) - enables direct connection to grounded sensors |
| Ultra-low input bias current | 0.6 pA typical at 25°C - preserves signal integrity in high-impedance pH electrodes, photodiode, and piezoelectric transducer circuits |
| ESD protection | 2000 V HBM rating per MIL-STD-883C - reduces handling sensitivity and improves board-level robustness |
| Latch-up immunity | Withstands −100 mA surge on inputs/outputs - prevents catastrophic failure during power sequencing or transient events |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27M2CP | Same electrical specs, PDIP-8 package instead of SOIC-8 | Through-hole assembly; larger footprint; higher parasitic capacitance | Select when legacy through-hole manufacturing or prototyping breadboarding is required |
| TLC27M2ACD | Lower 5 mV → 500 µV max VIO; otherwise identical SOIC-8 packaging and specs | Higher-precision applications requiring <0.1% DC accuracy (e.g., calibration references) | Select when tighter initial offset is mandatory and cost premium is acceptable |
Compared with TLC27M2CP, TLC27M2CD offers superior high-density layout compatibility and thermal performance; compared with TLC27M2ACD, it trades 10× higher offset tolerance for lower unit cost in non-critical DC gain stages.

FAQ
What is the maximum operating temperature range for the TLC27M2CD?
The TLC27M2CD is characterized for operation from 0°C to 70°C, as indicated by its "C" suffix. It supports supply voltages from 3 V to 16 V across this range. For extended temperature operation, consider the TLC27M2I (−40°C to 85°C) or TLC27M2M (−55°C to 125°C) variants, which share identical pinout and core specifications but differ in screening and offset grading.
Does the TLC27M2CD support true rail-to-rail input operation?
The TLC27M2CD does not support rail-to-rail input - its common-mode input voltage range extends to −0.2 V (below GND) and up to 3.5 V (at VDD = 5 V), but does not reach VDD. However, its output is rail-to-rail: it swings within 50 mV of GND and within 100 mV of VDD, making it suitable for driving ADCs and comparators in single-supply systems.
What is the typical supply current consumption of the TLC27M2CD?
The TLC27M2CD draws 210 µA typical supply current (IDD) per amplifier pair at VDD = 5 V and TA = 25°C, totaling ~420 µA for both channels. At 70°C, IDD remains below 440 µA. This low quiescent current enables multi-year battery life in always-on sensor nodes and portable instrumentation using the TLC27M2CD.
Can the TLC27M2CD drive capacitive loads directly?
The TLC27M2CD is stable with capacitive loads up to 20 pF, as verified in the datasheet's unity-gain test configuration (Figure 1). Driving larger capacitive loads (e.g., >100 pF cables or ADC input caps) requires isolation via a series resistor (≥100 Ω) or external compensation to maintain phase margin ≥39° and prevent oscillation - a key design consideration when using the TLC27M2CD in data acquisition paths.
Is the TLC27M2CD pin-compatible with other devices in the TLC27Mx family?
Yes - all TLC27Mx dual op-amps (including TLC27M2CD, TLC27M2ACD, TLC27M2BCD, TLC27M7CD, and their I/M-suffix variants) share identical SOIC-8 (D) and PDIP-8 (P) pinouts. This allows drop-in replacement for offset grade upgrades or temperature range extensions without PCB redesign - a verified compatibility confirmed across TI's SLOS051E datasheet package diagrams.
