Product details
Overview
TLC27M2ACD 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 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, 32 nV/√Hz input noise at 1 kHz, and 525 kHz unity-gain bandwidth - enabling low-power sensor signal conditioning in battery-powered industrial monitoring systems.
For engineers reviewing the TLC27M2ACD datasheet, TLC27M2ACD pinout, TLC27M2ACD application, or TLC27M2ACD equivalent, key selection criteria include its 5 mV offset grade (mid-precision tier), single-supply compatibility with extended common-mode range (–0.2 V to 3.5 V), low 210–560 µA supply current per dual amplifier, and SOIC-8 packaging for space-constrained analog front-ends.
Technical Context
The TLC27M2ACD 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 architecture supports true single-supply operation with common-mode input range extending below ground.
It features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2), latch-up immunity, and robust output drive capability (±30 mA) while maintaining low power consumption - making it suitable for interfacing high-impedance transducers without external level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 5 mV max at 25°C - defines mid-precision grade for cost-sensitive analog signal conditioning where sub-mV accuracy is not required. |
| Supply Voltage Range | 3 V to 16 V - enables direct operation from single Li-ion cells (3.0–4.2 V) up to industrial 12 V rails without regulation. |
| Common-Mode Input Range | –0.2 V to 3.5 V at VDD = 5 V - allows input signals below ground, eliminating need for negative supply in single-supply systems. |
| Slew Rate | 0.40 V/µs typ at VDD = 5 V - supports bandwidth-limited sensor amplification (e.g., thermocouples, strain gauges) without distortion. |
| Unity-Gain Bandwidth | 525 kHz typ at VDD = 5 V - sufficient for anti-aliasing filters and active instrumentation amplifier gain stages. |
| Input Noise Density | 32 nV/√Hz at f = 1 kHz - low enough for millivolt-level transducer outputs without dominating system noise floor. |
| Supply Current | 210–560 µA per dual amplifier - enables multi-channel analog front-ends in energy-constrained remote sensing nodes. |
Pinout & Package
Package: SOIC-8 (D package), surface-mount, 150 mil width, JEDEC MS-012AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Amplifier 1 output | Drives load directly; rail-to-rail swing includes negative rail - simplifies single-supply output interfacing. |
| 2 (IN−1) | Inverting input, Amp 1 | High-impedance node (10¹² Ω); accepts differential or single-ended signals referenced to ground or negative rail. |
| 3 (IN+1) | Non-inverting input, Amp 1 | Same high-Z as IN−1; enables non-inverting gain configurations with minimal loading on source. |
| 4 (GND) | Ground reference | Return path for both amplifiers; common reference for inputs, outputs, and supply decoupling. |
| 5 (IN+2) | Non-inverting input, Amp 2 | Independent channel input; allows dual-path signal processing (e.g., differential pair + reference buffer). |
| 6 (IN−2) | Inverting input, Amp 2 | Matches Amp 1 input characteristics; supports matched dual-channel designs like instrumentation amps. |
| 7 (OUT2) | Amplifier 2 output | Functionally identical to OUT1; enables independent second-stage gain or filtering without external op-amps. |
| 8 (VCC) | Positive supply | Accepts 3–16 V; no separate VEE required - reduces BOM count and PCB area in single-supply systems. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing including negative rail | Enables full dynamic range utilization in single-supply systems without level-shifting circuitry. |
| Input common-mode range extends below GND | Supports transducer signals with negative excursions (e.g., bridge sensors, thermocouples) without external biasing. |
| Ultra-low input bias current (0.6 pA typ) | Minimizes voltage error across high-impedance sources (e.g., pH electrodes, piezoelectric sensors). |
| ESD protection (2000 V HBM) | Reduces need for external protection components in production environments with moderate ESD risk. |
| Designed-in latch-up immunity | Ensures robust operation during transient overvoltage events without destructive failure modes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27M2CD | 10 mV max input offset voltage - double the offset of TLC27M2ACD. | Lower precision; acceptable where cost is prioritized over accuracy (e.g., non-critical threshold detection). | Select when budget constraints outweigh offset sensitivity requirements and system calibration is not feasible. |
| TLC27M2BCD | 2 mV max input offset voltage - four times tighter than TLC27M2ACD. | Higher precision grade; requires tighter layout control to avoid noise coupling into lower-offset path. | Choose when improved DC accuracy justifies higher unit cost and potential need for guard traces or shielding. |
Compared with TLC27M2CD and TLC27M2BCD, the TLC27M2ACD provides optimal balance between offset performance (5 mV), cost, and design simplicity - delivering measurable improvement over the 10 mV grade without the layout sensitivity or premium pricing of the 2 mV variant.

FAQ
What is the maximum input offset voltage specification for TLC27M2ACD at 25°C?
The TLC27M2ACD has a maximum input offset voltage of 5 mV at 25°C, as specified in the electrical characteristics table under VDD = 5 V test conditions. This value applies across the full operating temperature range (0°C to 70°C) with a worst-case limit of 6.5 mV, making it a mid-precision grade within the TLC27Mx family.
Does TLC27M2ACD support true single-supply operation with inputs below ground?
Yes, the TLC27M2ACD supports true single-supply operation with its common-mode input voltage range extending to –0.2 V at VDD = 5 V. This allows direct connection of transducer signals with negative DC offsets (e.g., thermocouples) without external biasing networks - a key feature confirmed in the recommended operating conditions table.
What is the typical supply current consumption of TLC27M2ACD at 25°C and VDD = 5 V?
The TLC27M2ACD draws 210 µA typical supply current (for both amplifiers combined) at 25°C and VDD = 5 V, with a maximum of 560 µA across the full 0°C to 70°C range. This low quiescent current enables multi-channel analog front-ends in battery-powered devices without compromising runtime.
Can TLC27M2ACD drive capacitive loads up to 20 pF while maintaining stability?
Yes, the TLC27M2ACD is characterized for stability with 20 pF capacitive loads, as evidenced by phase margin measurements (40° typ at 25°C) and unity-gain bandwidth testing in the operating characteristics section. The datasheet confirms stable operation under these conditions without requiring external compensation.
Is the SOIC-8 package of TLC27M2ACD compatible with standard reflow soldering profiles?
Yes, the TLC27M2ACD in SOIC-8 (D) package is qualified for standard lead-free reflow soldering with a peak temperature of 260°C for 10 seconds at 1.6 mm from the case, as specified in the absolute maximum ratings table - ensuring compatibility with automated PCB assembly processes.
