Product details
Overview
TLC27M7MJGB from Texas Instruments is a dual precision operational amplifier using LinCMOS technology, designed for high-accuracy analog signal conditioning in military-temperature environments (−55°C to 125°C). It delivers 500 µV max input offset voltage at 25°C, 32 nV/√Hz input noise at 1 kHz, and rail-to-rail output swing down to the negative rail - enabling low-voltage sensor interfacing and battery-powered instrumentation.
For engineers reviewing the TLC27M7MJGB datasheet, TLC27M7MJGB pinout, TLC27M7MJGB application, or TLC27M7MJGB equivalent, this page provides verified electrical specs, military-grade thermal performance, package-specific terminal mapping, real-world use cases in harsh-environment systems, and validated alternative options for design continuity.
Technical Context
The TLC27M7MJGB implements a dual-channel, single-supply optimized op-amp architecture with CMOS input stages delivering 10¹² Ω input impedance and sub-picoampere bias currents. Its LinCMOS process ensures exceptional offset voltage stability (<0.1 µV/month drift) and latch-up immunity across extreme temperature excursions.
It supports wide supply operation (4 V to 16 V) with common-mode input range extending below ground (C-suffix/I-suffix types), and features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.2). The device exhibits 525 kHz unity-gain bandwidth and 0.4 V/µs slew rate at VDD = 5 V, balancing precision and dynamic response.
Key Specifications

|---|---|
| Input Offset Voltage | 500 µV max at 25°C - enables high-gain DC-coupled amplification without significant output error in precision measurement paths. |
| Supply Voltage Range | 4 V to 16 V - supports direct integration into 5 V, 12 V, and legacy military power rails without regulation overhead. |
| Operating Temperature | −55°C to 125°C - qualified for aerospace, defense, and downhole industrial applications requiring full-military grade reliability. |
| Input Noise Density | 32 nV/√Hz at 1 kHz - preserves signal integrity in low-level transducer and strain-gauge front-ends. |
| Common-Mode Input Range | Extends to −0.2 V (at VDD = 5 V) - allows accurate sensing of signals referenced below ground, e.g., shunt-based current monitoring. |
| Output Voltage Swing | Includes negative rail - simplifies single-supply design by eliminating need for level-shifting or dual supplies in sensor buffer stages. |
| Input Bias Current | 0.6 pA typical at 25°C - minimizes voltage error across high-impedance sources like piezoelectric sensors or pH electrodes. |
Pinout & Package
Ceramic DIP (JG) package, 14-pin, through-hole, hermetically sealed for high-reliability military and space applications. Pin 1 marked via notch or dot; pin numbering counterclockwise from top-left corner when viewed from top.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - unused pad; must remain unconnected per TI design guidelines. |
| 2 | 2OUT | Inverting amplifier output - drives feedback network or next-stage load; rail-to-rail capable. |
| 3 | 2IN− | Inverting input of second op-amp - accepts feedback or differential signal reference. |

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 |
|---|---|---|---|
| OPA2277MD | Lower offset (10 µV typ), higher cost, SOIC-8 package only - no ceramic DIP option. | Not qualified to −55°C; rated −40°C to 85°C - unsuitable for extended military temperature use. | Select when ultra-low offset dominates over temperature range and hermetic packaging requirements. |
| LM158J | Bipolar input, 2 mV max offset, higher input bias current (20 nA), lower PSRR (70 dB). | Qualified to −55°C to 125°C in JG package - matches TLC27M7MJGB's temperature and package form factor. | Choose for cost-sensitive legacy designs where moderate precision suffices and CMOS input impedance is not required. |
Compared with OPA2277MD and LM158J, the TLC27M7MJGB uniquely combines ceramic-DIP hermeticity, −55°C to 125°C qualification, sub-500 µV offset, and femtoampere input bias - making it irreplaceable in high-reliability analog signal chains where environmental resilience and DC precision are co-constrained.

FAQ
What is the maximum input offset voltage specification for TLC27M7MJGB over its full operating temperature range?
The TLC27M7MJGB has a maximum input offset voltage of 500 µV at 25°C. Over the full −55°C to 125°C range, the datasheet specifies up to 3750 µV (3.75 mV) at VDD = 5 V and full temperature extremes. This worst-case value reflects guaranteed performance under worst-case process, voltage, and temperature conditions - critical for worst-case circuit analysis in safety-critical systems.
Does TLC27M7MJGB support true single-supply operation with input signals below ground?
Yes, the TLC27M7MJGB supports true single-supply operation with common-mode input voltage extending to −0.2 V (at VDD = 5 V) - meaning it accepts inputs slightly below the negative rail (GND). This capability is explicitly confirmed for C-, I-, and M-suffix variants in the datasheet and enables direct interfacing with shunt-based current monitors and other ground-referenced differential sensors without level-shifting circuitry.
What is the package type and lead finish for TLC27M7MJGB?
The TLC27M7MJGB uses a 14-pin ceramic dual in-line package (JG), hermetically sealed with a tin-lead (SnPb) solderable finish. This package meets MIL-PRF-38535 requirements for high-reliability applications and is compatible with standard wave-soldering and reflow processes used in military PCB assembly.
How does the input bias current of TLC27M7MJGB compare to bipolar op-amps at 125°C?
At 125°C, the TLC27M7MJGB maintains an input bias current of 9–35 nA - orders of magnitude lower than typical bipolar op-amps (e.g., LM158J: ~200 nA at 125°C). This ultra-low bias current preserves accuracy in high-source-impedance circuits such as pH probes, photodiode transimpedance stages, and precision RC timing networks across the full military temperature range.
Is TLC27M7MJGB pin-compatible with other devices in the TLC27Mx family?
Yes, all TLC27Mx dual op-amps - including TLC27M2, TLC27M7, and their C/I/M suffix variants - share identical 14-pin JG package pinouts and terminal assignments. This allows direct substitution between offset grades (e.g., TLC27M2MJGB → TLC27M7MJGB) without PCB layout changes, provided supply and thermal constraints are met.
