Product details
Overview
TLC27M2ACP from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, designed for single-supply operation with rail-to-rail output swing and input common-mode range extending below ground. It delivers 10 mV max input offset voltage at 25°C, 32 nV/√Hz input noise at 1 kHz, and 0.4 V/µs slew rate at VDD = 5 V - enabling accurate signal conditioning in low-power sensor interfaces and portable instrumentation.
For engineers reviewing the TLC27M2ACP datasheet, TLC27M2ACP pinout, TLC27M2ACP application, or TLC27M2ACP equivalent, this page provides verified specifications, package mapping to PDIP-8, real-world design implications of its LinCMOS architecture, and validated alternative options for cost-sensitive industrial analog front-ends.
Technical Context
The TLC27M2ACP implements a silicon-gate LinCMOS process that achieves ultra-high input impedance (10¹² Ω typ), sub-picoamp input bias current (0.6 pA typ at 25°C), and inherent latch-up immunity - distinguishing it from bipolar op-amps while matching their speed. Its internal ESD protection withstands 2000 V per MIL-STD-883C Method 3015.2.
It supports wide supply ranges (3–16 V) across 0°C to 70°C, features common-mode input voltage down to −0.2 V (below GND), and maintains stable phase margin (≥39°) under capacitive loads up to 20 pF - making it suitable for unity-gain stable configurations without external compensation.
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 and sensor amplifiers |
| Supply Voltage Range | 3 V to 16 V - enables direct operation from single Li-ion cells (3.0–4.2 V) or 12-V industrial rails |
| Slew Rate | 0.4 V/µs at VDD = 5 V - supports ≤50 kHz full-swing output bandwidth for buffered transducer signals |
| Input Noise Density | 32 nV/√Hz at 1 kHz - critical for low-level thermocouple or strain gauge amplification |
| Common-Mode Input Range | −0.2 V to 3.5 V at VDD = 5 V - allows direct interfacing with grounded sensors and single-supply ADC drivers |
| Output Voltage Swing | 0 V to VDD − 0.5 V - delivers rail-referenced logic-compatible outputs without level-shifting circuitry |
| Supply Current (dual) | 210–560 µA at 25°C - enables multi-year battery life in remote monitoring nodes |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier A) | High-impedance node for feedback network connection; accepts signals down to −0.2 V |
| 2 | Non-Inverting Input (Amplifier A) | Reference point for differential sensing; supports ground-referenced inputs |
| 3 | Output (Amplifier A) | Capable of sourcing/sinking ±30 mA; swings to within 50 mV of GND and 0.5 V of VDD |
| 4 | GND | Power and signal reference plane; must be low-impedance for noise rejection |
| 5 | Non-Inverting Input (Amplifier B) | Independent second channel input; identical electrical specs to Pin 2 |
| 6 | Inverting Input (Amplifier B) | Second channel feedback node; supports independent gain configuration |
| 7 | Output (Amplifier B) | Second fully buffered output; electrically isolated from Channel A except via shared VDD/GND |

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 |
|---|---|---|---|
| TLC27M2BCP | Same package and pinout; 2 mV max VIO vs. 10 mV - tighter initial offset but higher cost | Better for DC-critical applications like precision weight scales where <2 mV error budget is mandatory | Select when system-level offset calibration is impractical and hardware accuracy must be guaranteed at production test |
| LM358AP | Bipolar process; 7 mV max VIO, 0.3 V/µs slew, no sub-pA bias current - lower input impedance (2 MΩ) | Higher power (700 µA/channel), less suitable for battery operation or high-Z sources | Choose only if legacy LM358 footprint reuse is required and LinCMOS benefits (bias current, noise, supply range) are non-critical |
Compared with TLC27M2BCP, TLC27M2ACP trades initial offset accuracy for lower cost and sufficient performance in mid-precision industrial sensing; versus LM358AP, it delivers 10⁶× lower input bias current and 3× better noise performance at half the supply current - justifying redesign for new low-power or high-impedance designs.

FAQ
What is the maximum operating temperature range for the TLC27M2ACP?
The TLC27M2ACP is characterized for operation from 0°C to 70°C, as indicated by its 'C' suffix. This commercial-grade temperature range is validated per TI's SLOS051E datasheet and applies to all electrical specifications unless otherwise noted. The device remains functional outside this range but is not tested or guaranteed for parametric performance beyond 70°C or below 0°C.
Does the TLC27M2ACP support true rail-to-rail input operation?
No, the TLC27M2ACP 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, meaning it accepts inputs slightly below ground but cannot reach the positive rail. However, its output does swing to within 50 mV of GND and 0.5 V of VDD - providing near rail-to-rail output capability essential for single-supply systems.
Can the TLC27M2ACP drive capacitive loads directly?
Yes, the TLC27M2ACP is unity-gain stable and characterized with 20 pF capacitive load in its operating characteristics tables. At VDD = 5 V and 25°C, it maintains ≥39° phase margin under this condition, supporting direct driving of ADC input capacitors or long PCB traces without external isolation resistors - though layout best practices (short traces, local decoupling) remain essential for stability.
What is the typical input bias current of the TLC27M2ACP at room temperature?
The typical input bias current of the TLC27M2ACP is 0.6 pA at 25°C, as specified in the Electrical Characteristics table for VDD = 5 V. This ultra-low value - enabled by LinCMOS technology - minimizes voltage errors across high-value feedback resistors and makes the device ideal for integrating capacitors, photodiode transimpedance stages, and other high-impedance signal paths where bias current-induced offsets dominate error budgets.
Is the TLC27M2ACP pin-compatible with other devices in the TLC27Mx family?
Yes, all TLC27Mx dual op-amps - including TLC27M2ACP, TLC27M2BCP, TLC27M7CP, and their I/M-suffix variants - share identical PDIP-8 pinouts and package footprints. This allows drop-in replacement across offset voltage grades (2 mV, 5 mV, 10 mV, 500 µV) and temperature grades (C, I, M) without PCB layout changes, enabling flexible prototyping and production binning based on test results.
