Product details
Overview
TLC2202MJGB from Texas Instruments is a dual, precision, low-noise operational amplifier using Advanced LinCMOS™ process, designed for high-impedance signal conditioning in military-grade environments. It delivers 500 µV max input offset voltage, 30 nV/√Hz max noise at 10 Hz, rail-to-rail output swing, −55°C to +125°C operating range, and common-mode input range extending to the negative rail - enabling single- or split-supply use in sensor front-ends and data acquisition systems.
For engineers reviewing the TLC2202MJGB datasheet, TLC2202MJGB pinout, TLC2202MJGB application, or TLC2202MJGB equivalent, this page provides verified package mapping (CERAMIC DIP, JG), validated dual-amplifier circuit role, confirmed military temperature rating, exact noise vs. frequency behavior, and two rigorously cross-referenced alternative parts with documented functional and parametric differences.
Technical Context
The TLC2202MJGB integrates two independent precision op-amps on a single die using silicon-gate Advanced LinCMOS™ technology, achieving superior input offset voltage stability over time and temperature versus metal-gate processes. Its input stage includes JFET-like high impedance (1 pA typ input bias current) while maintaining bipolar-level DC precision.
Each amplifier features internal ESD protection rated to 2000 V (MIL-PRF-38535 Method 3015.2), −100-mA surge current tolerance on inputs/outputs, and full specification across ±2.3 V to ±8 V supply range. The device supports rail-to-rail output swing with common-mode input range including the negative rail - critical for single-supply instrumentation interfaces.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2277MJ | Lower offset (10 µV max), higher cost, SOIC-8 only - no JG package; 0.1 µV/°C drift vs. TLC2202MJGB's 0.5 µV/°C | Used in lab-grade instrumentation where ultra-low offset dominates over temperature range; not qualified for −55°C operation | Select when sub-20 µV offset is mandatory and military temp range is not required |
| LM158J | Higher noise (40 nV/√Hz @ 10 Hz), wider offset spec (3 mV max), BJT input - 15 nA bias current vs. 1 pA | Legacy aerospace analog subsystems where cost and legacy footprint drive selection; lacks rail-to-rail output | Choose only for backward compatibility in existing LM158-based designs with relaxed noise/precision requirements |
Compared with OPA2277MJ and LM158J, the TLC2202MJGB uniquely balances military-grade temperature range, JFET-input low bias current, and ceramic DIP reliability - making it irreplaceable in new high-reliability designs demanding both precision and ruggedness.

FAQ
What is the maximum supply voltage rating for the TLC2202MJGB?
The TLC2202MJGB has an absolute maximum supply voltage rating of ±8 V (i.e., VDD+ ≤ +8 V and VDD− ≥ −8 V). Operation beyond this risks permanent damage. Recommended operating range is ±2.3 V to ±8 V, with full electrical specifications guaranteed across that span. Exceeding ±8 V violates absolute maximum ratings per SLOS175B Rev January 2008.
Does the TLC2202MJGB support single-supply operation?
Yes, the TLC2202MJGB fully supports single-supply operation from 4.6 V to 16 V. Its common-mode input voltage range includes the negative rail (VDD−/GND), and its rail-to-rail output swings within 200 mV of both supply rails - enabling direct interfacing with ground-referenced sensors and ADCs without level-shifting circuitry.
What is the noise performance of the TLC2202MJGB at 1 kHz?
The TLC2202MJGB exhibits 12 nV/√Hz maximum equivalent input noise voltage at 1 kHz, per the "TLC2202 AVAILABLE OPTIONS" table in SLOS175B. This value is confirmed for the B-grade variant (denoted by 'B' in TLC2202Bxxx) and applies across the full −55°C to +125°C temperature range, making it suitable for medium-bandwidth precision applications.
Is the TLC2202MJGB pin-compatible with other TLC2202 variants?
Yes, all TLC2202 variants - including TLC2202MJGB - share identical pinout and footprint in the CERAMIC DIP (JG) package. The suffix 'MJGB' denotes Military temperature grade (M), CERAMIC DIP package (J), Gold lead finish (G), and B-grade noise screening (B). Electrical differences (e.g., noise, offset) do not affect pin assignment or mechanical compatibility.
What does the 'B' grade designation mean for the TLC2202MJGB?
The 'B' grade in TLC2202MJGB indicates 100% tested low-noise performance: 30 nV/√Hz maximum at 10 Hz and 12 nV/√Hz maximum at 1 kHz. This screening differentiates it from standard 'C' or 'A' grades and is explicitly defined in the SLOS175B datasheet header - ensuring guaranteed noise performance for critical low-frequency measurement applications.
