Product details
Overview
TLC27M2IDR from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, designed for single-supply operation with rail-to-rail input capability extending below the negative rail. 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 TLC27M2IDR datasheet, TLC27M2IDR pinout, TLC27M2IDR application, or TLC27M2IDR equivalent, this page provides verified package mapping (SOIC-8), temperature-rated performance (−40°C to 85°C), key electrical boundaries (4–16 V supply, ±30 mA output), and real-world design implications for low-power precision amplification.
Technical Context
The TLC27M2IDR implements silicon-gate LinCMOS process technology to achieve ultra-high input impedance (10¹² Ω typ), sub-picoampere input bias current (0.6 pA typ at 25°C), and latch-up immunity - distinguishing it from bipolar op-amps while retaining comparable speed. Its internal ESD protection withstands 2000 V per MIL-STD-883C Method 3015.2.
Designed explicitly for single-supply systems, the device supports common-mode input voltage down to −0.2 V (at VDD = 5 V) and output swing to within 50 mV of ground. It operates across −40°C to 85°C with guaranteed 10 mV input offset voltage and 525 kHz unity-gain bandwidth at 25°C.
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 offset correction circuits |
| Supply Voltage Range | 4 V to 16 V over −40°C to 85°C - enables direct use with 5 V, 9 V, or 12 V industrial rails without regulation |
| Slew Rate | 0.43 V/µs at VDD = 5 V - supports audio-band and medium-speed control loop signals without distortion |
| Input Noise Density | 32 nV/√Hz at f = 1 kHz - critical for low-level transducer amplification where thermal noise dominates |
| Common-Mode Input Range | Extends to −0.2 V below GND at VDD = 5 V - allows direct interfacing with grounded sensors or current-sense shunts |
| Output Current Drive | ±30 mA per amplifier - sufficient to drive 100 kΩ loads or moderate-capacitance cables without buffering |
| Unity-Gain Bandwidth | 525 kHz at 25°C - defines stable closed-loop bandwidth for non-inverting configurations up to ~500 kHz |
Pinout & Package
Package: SOIC-8 (D package), surface-mount, 150 mil width, tape-and-reel compatible (R suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Delivers buffered, inverted or non-inverted signal; capable of ±30 mA sink/source |
| 2 (IN− A) | Inverting input A | High-impedance node (10¹² Ω); accepts differential or single-ended feedback networks |
| 3 (IN+ A) | Non-inverting input A | Accepts reference, sensor, or signal source; common-mode range includes GND |
| 4 (GND) | Analog ground reference | Return path for both amplifiers; must be low-impedance to minimize PSRR degradation |
| 5 (IN+ B) | Non-inverting input B | Independent high-Z input for second channel; shares same supply and ground |
| 6 (IN− B) | Inverting input B | Supports dual-channel configurations like instrumentation amps or dual-filter stages |
| 7 (OUT B) | Amplifier B output | Electrically isolated output stage; no crosstalk specified beyond typical CMRR >60 dB |
| 8 (VDD) | Positive supply rail | Single power connection; no separate VSS required - simplifies PCB layout in unipolar systems |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input (below GND) | Enables direct connection to 0 V-referenced sources (e.g., shunt current sensors) without level-shifting circuitry |
| Low input bias current (0.6 pA typ) | Minimizes voltage error across high-impedance sources such as pH electrodes or photodiode transimpedance nodes |
| ESD protection (2000 V HBM) | Reduces need for external protection in field-deployed equipment handling electrostatic environments |
| Single-supply optimized architecture | Eliminates dual-rail generation in portable or remote systems - cuts BOM cost and board space |
| Latch-up immunity | Prevents catastrophic failure during transient overvoltage or hot-plug events in industrial I/O modules |

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 |
|---|---|---|---|
| TLV272IDR | Lower VIO (2 mV max), lower supply current (110 µA), but narrower supply range (2.7–16 V) and reduced output drive (±8 mA) | Better for ultra-low-power, high-accuracy apps where load current <10 mA; unsuitable for driving heavy capacitive loads | Select TLV272IDR when VIO <2 mV is mandatory and output loading is light; retain TLC27M2IDR for robust ±30 mA drive and proven industrial temp stability |
| LMV358IDR | Higher VIO (7 mV max), higher noise (42 nV/√Hz), but rail-to-rail output and wider temp range (−40°C to 125°C) | Preferred for cost-sensitive consumer apps needing RRO; less suitable for low-noise sensor front-ends | Choose LMV358IDR only if rail-to-rail output is essential and noise/offset specs are secondary; TLC27M2IDR remains superior for precision analog sensing |
Compared with TLV272IDR and LMV358IDR, the TLC27M2IDR uniquely balances 10 mV VIO, 32 nV/√Hz noise, ±30 mA drive, and −40°C to 85°C operation - making it the most versatile choice for industrial analog signal chains where reliability and moderate precision coexist.

FAQ
What is the maximum operating temperature range for the TLC27M2IDR?
The TLC27M2IDR is characterized for operation from −40°C to +85°C, as confirmed by its I-suffix designation and electrical specifications tables covering full-range testing at those extremes. This makes it suitable for under-hood automotive, factory-floor, and outdoor industrial deployments where ambient temperatures exceed commercial-grade limits.
Does the TLC27M2IDR support true single-supply operation with inputs referenced to ground?
Yes - the TLC27M2IDR features a common-mode input voltage range that extends to −0.2 V below GND at VDD = 5 V, allowing direct connection of grounded sensors (e.g., current-sense shunts or thermocouples) without external level-shifting circuitry. This is explicitly documented in the recommended operating conditions table.
What is the typical supply current consumption of the TLC27M2IDR at 5 V?
The TLC27M2IDR draws 210 µA typical supply current per amplifier (420 µA total for both channels) at VDD = 5 V and 25°C, as specified in the electrical characteristics table. At 85°C, this rises to 400 µA max for both amplifiers - a key parameter for battery-life calculations in portable designs.
Can the TLC27M2IDR drive capacitive loads without instability?
The TLC27M2IDR exhibits 40° phase margin at unity gain with 20 pF load (VDD = 5 V, 25°C), indicating conditional stability. For loads >100 pF, external compensation (e.g., series resistor at output) is recommended. The datasheet does not guarantee stability with purely capacitive loads above 20 pF without modification.
Is the TLC27M2IDR pin-compatible with other devices in the TLC27xx family?
Yes - all TLC27Mx dual op-amps in SOIC-8 (D) package share identical pinout: OUT A, IN− A, IN+ A, GND, IN+ B, IN− B, OUT B, VDD. This allows drop-in substitution between TLC27M2IDR, TLC27M7IDR, and TLC27M2CDR within the same footprint, provided system-level VIO and bandwidth requirements align.
