Product details
Overview
TLC27M2CPG4 from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, featuring 10 mV max input offset voltage at 25°C, 0.4 V/µs slew rate at VDD = 5 V, and rail-to-rail output swing down to GND. It operates from 3 V to 16 V supply over 0°C to 70°C and supports single-supply sensor signal conditioning in battery-powered instrumentation.
For engineers reviewing the TLC27M2CPG4 datasheet, TLC27M2CPG4 pinout, TLC27M2CPG4 application, or TLC27M2CPG4 equivalent, this page delivers verified electrical specs, package mapping, thermal performance across temperature grades, and real-world design context for analog front-end upgrades and low-power transducer interfacing.
Technical Context
The TLC27M2CPG4 implements silicon-gate LinCMOS process architecture, delivering high input impedance (10¹² Ω typ), ultra-low input bias current (0.6 pA typ at 25°C), and ESD protection rated to 2000 V per MIL-STD-883C Method 3015.2. Its input stage extends common-mode range below the negative rail, enabling true single-supply operation with ground-referenced inputs.
It features internal compensation for unity-gain stability, 525 kHz unity-gain bandwidth at VDD = 5 V, and phase margin of 40° at full temperature range. The device avoids latch-up under ±100-mA surge currents and maintains 60 dB CMRR minimum across its operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 10 mV max at 25°C - sets DC accuracy limit in precision gain stages and active filters |
| Supply Voltage Range | 3 V to 16 V - enables direct interface with 3.3 V, 5 V, and 12 V systems without level-shifting |
| Slew Rate | 0.4 V/µs at VDD = 5 V - supports audio-band signal amplification and moderate-speed sensor outputs |
| Input Bias Current | 0.6 pA typ at 25°C - minimizes voltage error in high-impedance source applications (e.g., pH electrodes) |
| Common-Mode Input Range | Extends to −0.2 V below GND at VDD = 5 V - allows ground-referenced differential sensing without level shifters |
| Output Voltage Swing | Includes GND (low-level output ≤50 mV) - simplifies interfacing with ADCs and logic inputs in single-supply systems |
| Quiescent Supply Current | 210 µA typ per amplifier at 25°C - enables multi-channel analog front-ends in energy-constrained devices |
Pinout & Package
Package: 8-pin PDIP (Plastic Dual In-line Package), body width 0.300 inch, standard through-hole mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier 1) | Accepts feedback or signal inversion node; high-impedance input requires guarded layout |
| 2 | Non-Inverting Input (Amplifier 1) | Reference or signal input node; supports rail-to-rail common-mode range including GND |
| 3 | Output (Amplifier 1) | Delivers rail-to-rail output swing; capable of sourcing/sinking ±30 mA short-term |
| 4 | GND | Analog ground reference; must be low-impedance connection to minimize noise coupling |
| 5 | Non-Inverting Input (Amplifier 2) | Independent second channel input; identical electrical characteristics to Pin 2 |
| 6 | Inverting Input (Amplifier 2) | Second channel inverting node; shares same high-Z, low-IB behavior as Pin 1 |
| 7 | Output (Amplifier 2) | Second independent output; fully decoupled from Channel 1 except via shared VDD/GND paths |
| 8 | VCC | Positive supply rail; requires local 0.1 µF ceramic bypass capacitor to GND for stability |
Key Features
| Feature | Design Value |
|---|---|
| LinCMOS Process Technology | Enables 10¹² Ω input impedance and sub-pA bias current - critical for high-Z sensor interfaces |

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 die, identical electrical specs, but in standard plastic DIP (no G4 suffix); RoHS-compliant finish not guaranteed | No lead-free plating; unsuitable for lead-free assembly processes requiring Pb-free terminations | Select TLC27M2CPG4 when RoHS compliance and Pb-free solder compatibility are required for final production. |
| TLV272CP | Lower VIO (2 mV max), higher quiescent current (1.25 mA), rail-to-rail input/output, 3 MHz GBW | Higher speed and precision at cost of 6× higher supply current - better for AC-coupled, higher-bandwidth designs | Choose TLV272CP where improved DC accuracy and full rail-to-rail I/O justify increased power consumption. |

FAQ
What is the maximum input offset voltage specification for TLC27M2CPG4 at 25°C?
The TLC27M2CPG4 has a maximum input offset voltage of 10 mV at 25°C, as specified in the Electrical Characteristics table for the TLC27M2C grade under VDD = 5 V conditions. This value applies across the full 0°C to 70°C operating range, with typical drift of 1.7 µV/°C between 25°C and 70°C. The parameter is measured with VO = 1.4 V and VIC = 0 V.
Does TLC27M2CPG4 support true single-supply operation with inputs referenced to ground?
Yes, the TLC27M2CPG4 supports true single-supply operation with inputs referenced to ground. Its common-mode input voltage range extends to −0.2 V below GND at VDD = 5 V, and its output swings fully to GND (≤50 mV low-level output). This enables direct interface with ground-referenced sensors and ADCs without level-shifting circuitry.
What is the recommended bypass capacitor for TLC27M2CPG4 on the VCC pin?
A 0.1 µF ceramic capacitor placed as close as possible between Pin 8 (VCC) and Pin 4 (GND) is recommended for TLC27M2CPG4. This provides effective high-frequency decoupling and ensures stability during fast output transitions. For systems with noisy power rails, adding a 10 µF tantalum or aluminum electrolytic capacitor in parallel improves low-frequency regulation.
How does the slew rate of TLC27M2CPG4 vary with supply voltage and temperature?
The TLC27M2CPG4 delivers 0.4 V/µs typical slew rate at VDD = 5 V and 25°C, decreasing to 0.36 V/µs at 70°C. At VDD = 10 V, the typical slew rate increases to 0.56 V/µs at 25°C and 0.51 V/µs at 70°C. These values are measured under unity-gain configuration with RL = 100 kΩ and CL = 20 pF.
Is TLC27M2CPG4 pin-compatible with other devices in the TLC27Mx family?
Yes, the TLC27M2CPG4 is pin-compatible with all members of the TLC27Mx dual op-amp family in the 8-pin PDIP package, including TLC27M2ACP, TLC27M2BCP, TLC27M7CP, and their I-suffix and M-suffix variants. All share identical pinout, footprint, and terminal functions - only electrical specifications (e.g., VIO, IIB) differ by grade and temperature rating.
