Product details
Overview
TLC27M2IDG4 from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, designed for single-supply operation across −40°C to 85°C. It delivers 10 mV max input offset voltage at 25°C, 32 nV/√Hz input noise at 1 kHz, and 0.43 V/µs slew rate at VDD = 5 V - enabling accurate signal conditioning in battery-powered sensor interfaces and industrial analog front-ends.
For engineers reviewing the TLC27M2IDG4 datasheet, TLC27M2IDG4 pinout, TLC27M2IDG4 application, or TLC27M2IDG4 equivalent, key selection criteria include its rail-to-rail output swing, common-mode input range extending below ground, low 210–560 µA supply current per amplifier pair, and guaranteed performance over extended temperature.
Technical Context
The TLC27M2IDG4 implements a silicon-gate LinCMOS process that achieves high input impedance (10¹² Ω typ), ultra-low input bias current (0.6 pA typ at 25°C), and inherent latch-up immunity. Its architecture supports stable unity-gain operation with 40° phase margin and 525 kHz unity-gain bandwidth at VDD = 5 V.
It operates from 4 V to 16 V supply rails, with common-mode input voltage range specified down to −0.2 V (at VDD = 5 V) and output swing including the negative rail. ESD protection meets MIL-STD-883C, Method 3015.2 (2000 V HBM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 10 mV max at 25°C - defines worst-case DC error in precision gain stages and sensor amplifiers |
| Supply Voltage Range | 4 V to 16 V - supports wide-input industrial and automotive power rails without regulation |
| Operating Temperature | −40°C to +85°C - qualified for industrial and extended-temperature embedded systems |
| Slew Rate | 0.43 V/µs at VDD = 5 V - enables stable amplification of low-frequency signals up to ~55 kHz full-swing |
| Input Noise Density | 32 nV/√Hz at f = 1 kHz - suitable for low-level transducer signal conditioning without added noise floor |
| Supply Current (dual) | 210–560 µA at 25°C - allows multi-channel analog sensing in power-constrained remote nodes |
| Common-Mode Input Range | Extends to −0.2 V below ground at VDD = 5 V - permits direct interfacing with unipolar sensors and current-sense shunts |
Pinout & Package
Package: SOIC-8 (DG package), 8-pin small-outline integrated circuit with standard DIP footprint compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Amplifier A) | High-impedance node accepting differential signal reference; biased via external network |
| 2 | Non-inverting input (Amplifier A) | High-Z node for signal source connection; common-mode range includes negative rail |
| 3 | Output (Amplifier A) | Capable of rail-to-rail swing; drives loads ≥100 kΩ directly without buffering |
| 4 | GND | Analog ground reference; must be low-impedance return path for both amplifiers |
| 5 | Non-inverting input (Amplifier B) | Independent high-Z input; electrically isolated from Amplifier A inputs |
| 6 | Inverting input (Amplifier B) | Differential input node with same CMVR and bias specs as Pin 1 |
| 7 | Output (Amplifier B) | Second independent output; shares GND and VDD with Amplifier A |
| 8 | VDD | Positive supply rail; accepts 4–16 V; decoupling capacitor required at point-of-load |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives from GND to within ~100 mV of VDD - simplifies level-shifting in single-supply data acquisition |
| Input common-mode range below GND | Valid down to −0.2 V at VDD = 5 V - enables direct connection to current-sense resistors tied to ground |
| Ultra-low input bias current | 0.6 pA typical at 25°C - preserves accuracy in high-impedance pH, thermocouple, or photodiode interfaces |
| ESD protection | 2000 V HBM per MIL-STD-883C - reduces handling sensitivity during PCB assembly and field service |
| Latch-up immunity | Designed-in robustness against transient overcurrent - prevents catastrophic failure during power sequencing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27M2CP | Same electrical specs but rated for 0°C to 70°C only; PDIP-8 package | Limited to commercial-temperature environments; no extended-temp qualification | Select when operating ambient stays within 0–70°C and through-hole assembly is preferred |
| TLV2462IDR | Lower VIO (2 mV max), higher quiescent current (550 µA), rail-to-rail I/O, SOIC-8 | Better DC precision but higher power; requires tighter supply regulation | Choose for improved offset-critical designs where 3× higher supply current is acceptable |
Compared with TLC27M2CP, the TLC27M2IDG4 adds −40°C start-up capability and surface-mount reliability; versus TLV2462IDR, it trades 5× lower supply current for relaxed offset spec - making it optimal for long-life industrial nodes where power budget dominates precision.

FAQ
What is the maximum input offset voltage specification for TLC27M2IDG4 over temperature?
The TLC27M2IDG4 has a maximum input offset voltage of 10 mV at 25°C and 13 mV over its full −40°C to +85°C operating range, as confirmed in the "Electrical Characteristics" table for I-suffix devices at VDD = 5 V. This value reflects worst-case device-to-device variation under defined test conditions and is critical for DC-coupled gain stage accuracy.
Does TLC27M2IDG4 support true single-supply operation with inputs referenced to ground?
Yes, the TLC27M2IDG4 supports true single-supply operation: its common-mode input voltage range extends to −0.2 V at VDD = 5 V (and to 0 V at VDD = 10 V), allowing direct connection of inverting/non-inverting inputs to ground-referenced sources such as current-sense shunts or resistive sensors - no level-shifting circuitry required.
What is the typical supply current consumption of TLC27M2IDG4 at 25°C and VDD = 5 V?
The TLC27M2IDG4 draws 210–560 µA total supply current for both amplifiers at 25°C and VDD = 5 V, as specified in the "Electrical Characteristics" table. This low quiescent current enables multi-channel analog signal chains in energy-sensitive applications like wireless sensor nodes and portable instrumentation.
Is TLC27M2IDG4 pin-compatible with other devices in the TLC27Mx family?
Yes, all TLC27Mx dual op-amps in SOIC-8 (DG) package - including TLC27M2IDG4, TLC27M2ACDG4, TLC27M7IDG4 - share identical pinout and footprint. Functional differences (e.g., offset voltage grade, temperature range) do not affect mechanical or electrical connectivity, enabling drop-in replacement during design iteration or qualification.
What packaging and ordering options are available for TLC27M2IDG4?
TLC27M2IDG4 is supplied in SOIC-8 (DG) package, tape-and-reel format (standard order code: TLC27M2IDG4R). The "G4" suffix denotes RoHS-compliant, green (halogen-free) packaging per TI's standard manufacturing practice. No die-variant or wafer-level packaging options exist for this part number.
