Product details
Overview
TLC27M2MD from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, rated for −55°C to 125°C operation, with 10 mV max input offset voltage at 25°C, 32 nV/√Hz input voltage noise at 1 kHz, and rail-to-rail output swing down to the negative rail - used in military-grade sensor signal conditioning and high-reliability analog front-ends.
For engineers reviewing the TLC27M2MD datasheet, TLC27M2MD pinout, TLC27M2MD application, or TLC27M2MD equivalent, this page delivers verified electrical specs, military-temperature package mapping (D/PW/FK/MJG), real-world design implications of LinCMOS input impedance (>10¹² Ω), and validated alternatives for extended-temperature op-amp replacement.
Technical Context
The TLC27M2MD implements a silicon-gate LinCMOS process enabling ultra-low input bias current (0.6 pA typ at 25°C) and stable offset voltage drift (1.7 µV/°C over −55°C to 125°C). Its architecture supports single-supply operation with common-mode input range extending to the negative rail - critical for ground-referenced transducer interfaces.
It delivers 525 kHz unity-gain bandwidth and 0.4 V/µs slew rate at VDD = 5 V, with phase margin of 40° at 25°C. Internal ESD protection meets MIL-STD-883C, Method 3015.2 (2000 V), and latch-up immunity is designed-in per JEDEC JESD78.
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 without trimming |
| Supply Voltage Range | 4 V to 16 V over −55°C to 125°C - enables direct integration into 5 V, 12 V, or battery-backed military power rails |
| Input Bias Current | 0.6 pA typical at 25°C - allows use with high-impedance sources (e.g., piezoelectric sensors, pH electrodes) |
| Common-Mode Input Range | Extends to negative rail (0 V at VDD = 5 V) - supports true single-supply operation with ground-referenced inputs |
| Output Voltage Swing | Rail-to-rail low-side (VOL ≤ 50 mV at IOL = 0) - ensures full dynamic range utilization near GND in ADC driver stages |
| Input Voltage Noise | 32 nV/√Hz at 1 kHz - sets minimum detectable signal level in low-frequency instrumentation amplifiers |
| Unity-Gain Bandwidth | 525 kHz at VDD = 5 V, 25°C - determines maximum closed-loop bandwidth for stable non-inverting configurations |
Pinout & Package
Package: SOIC-8 (D), TSSOP-8 (PW), Ceramic DIP-8 (JG), and LCC-20 (FK) - TLC27M2MD is specified for SOIC-8 (D) per TI SLOS051E datasheet Table "AVAILABLE OPTIONS".
| Pin/Terminal | Circuit Role | Design Meaning |

IC Role / Device Role / Timing Role: Precision current-to-voltage converter and low-pass filter stage preceding isolation barrier and microcontroller ADC. Use Value: Input offset drift of 1.7 µV/°C limits calibration interval to once per year; ESD-hardened inputs survive industrial EMI events. |
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 |
|---|---|---|---|
| LM2904MWX/NOPB | Higher VIO (7 mV max), wider temp range (−40°C to 125°C), bipolar input (higher IB = 20 nA) | Lacks rail-to-rail output and LinCMOS low-noise performance; suited for cost-sensitive industrial controls | Select when budget constraints outweigh precision and low-power needs; verify layout for higher IB-induced errors |
| OPA2333AIDR | Zero-drift architecture, 12 µV max VIO, lower noise (5.5 nV/√Hz), but limited to −40°C to 125°C | Superior DC accuracy and drift, but not qualified for −55°C operation; requires external ESD protection | Choose for ultra-low-drift applications where military cold-start is not required; validate thermal derating above 85°C |
Compared with LM2904MWX/NOPB, TLC27M2MD offers 3× lower input bias current and rail-to-rail output - critical for high-impedance sensor interfaces; versus OPA2333AIDR, it trades zero-drift performance for guaranteed −55°C operation and integrated ESD robustness.

FAQ
What is the maximum input offset voltage specification for TLC27M2MD at 25°C?
The maximum input offset voltage for TLC27M2MD at 25°C is 10 mV, as specified in the "AVAILABLE OPTIONS" table of TI SLOS051E datasheet under the M-suffix row for TLC27M2MD. This value applies across the full military temperature range (−55°C to 125°C) with no additional derating required for initial calibration.
Does TLC27M2MD support true single-supply operation with inputs referenced to ground?
Yes, TLC27M2MD supports true single-supply operation: its common-mode input voltage range extends to the negative rail (0 V at VDD = 5 V), and output swings to within 50 mV of GND. This allows direct interface with ground-referenced sensors like thermocouples and strain gauges without level-shifting circuitry.
Which package variants are officially listed for TLC27M2MD in the TI datasheet?
TLC27M2MD is explicitly listed in TI SLOS051E for SOIC-8 (D), TSSOP-8 (PW), Ceramic DIP-8 (JG), and LCC-20 (FK) packages. The "AVAILABLE OPTIONS" table confirms TLC27M2MD (D), TLC27M2MFK (FK), TLC27M2MJG (JG), and TLC27M2MP (P) - all qualified for −55°C to 125°C operation.
What is the typical input bias current of TLC27M2MD at 25°C, and why does it matter?
The typical input bias current of TLC27M2MD at 25°C is 0.6 pA, enabled by its LinCMOS process. This ultra-low value prevents significant voltage drop across high-impedance sensor sources (e.g., >100 MΩ pH electrodes or piezoelectric elements), preserving signal integrity and eliminating the need for guard traces or active bias cancellation.
How does the slew rate of TLC27M2MD vary across its full temperature range?
TLC27M2MD's slew rate is 0.40 V/µs at 25°C (VDD = 5 V), degrades to 0.29 V/µs at 125°C, and improves to 0.54 V/µs at −55°C - per SLOS051E page 13. This inverse temperature dependence is characteristic of CMOS transconductance and must be accounted for in wide-temperature stability analysis of active filters or pulse amplifiers.
