Product details
Overview
TLC2274AMPWREP from Texas Instruments is a radiation-hardened, quad rail-to-rail output operational amplifier optimized for precision analog signal conditioning in extended-temperature aerospace and defense systems. It delivers 2.2 MHz gain-bandwidth product, 3.6 V/µs slew rate, 9 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and 950 µV maximum input offset voltage at 25°C - enabling high-fidelity amplification of low-level sensor signals in space-grade data acquisition front-ends.
For engineers reviewing the TLC2274AMPWREP datasheet, TLC2274AMPWREP pinout, TLC2274AMPWREP application, or TLC2274AMPWREP equivalent, this page provides verified electrical specifications, TSSOP-14 package terminal mapping, rail-to-rail output behavior under ±5 V and single 5 V supply, and validated alternatives for radiation-tolerant op-amp replacement in flight-critical analog circuits.
Technical Context
The TLC2274AMPWREP implements an Advanced LinCMOS™ input stage with complementary MOSFET pairs to achieve ultra-low input bias current (1 pA typ) and rail-inclusive common-mode input range (down to VDD−). Its fully differential output stage supports true rail-to-rail swing - delivering >4.85 V peak positive and <0.15 V peak negative output voltage into 500 µA load at 5 V supply - critical for maximizing dynamic range when driving SAR ADC inputs.
Designed for operation across −55°C to +125°C, it features controlled baseline manufacturing, enhanced DMS support, and qualification per JEDEC/industry standards including HAST, temperature cycling, and electromigration testing - ensuring reliability in mission-critical environments where component pedigree and long-term stability are mandatory.

FAQ
What is the maximum operating temperature range for the TLC2274AMPWREP?
The TLC2274AMPWREP is fully specified and qualified for continuous operation from −55°C to +125°C. This extended temperature range is validated per JEDEC JESD22-A108 and A110 standards, including biased 85/85, temperature cycling, and HAST testing - confirming suitability for satellite, avionics, and downhole electronics where ambient extremes are routine.
Does the TLC2274AMPWREP support single-supply operation?
Yes, the TLC2274AMPWREP is fully characterized for single-supply operation from 4.4 V to 16 V. Its common-mode input voltage range extends to VDD−, and its rail-to-rail output swings within 15 mV of both supply rails - enabling direct interfacing with 5 V or 3.3 V ADCs without level-shifting circuitry. Input and output specifications are guaranteed across the full supply range.
What is the input offset voltage specification for the TLC2274AMPWREP?
The TLC2274AMPWREP has a maximum input offset voltage of 950 µV at TA = 25°C and 1500 µV across the full −55°C to +125°C operating range. This value is guaranteed per the datasheet's "TLC2274A-EP" grade, which applies to the AMPWREP variant. The typical offset is 300 µV at 25°C, with a temperature coefficient of 2 µV/°C.
Is the TLC2274AMPWREP pin-compatible with the standard TLC2274 series?
Yes, the TLC2274AMPWREP uses the same TSSOP-14 (PW) package and identical pinout as the commercial TLC2274 and industrial TLC2274A variants. Pin assignments for all 14 terminals - including independent IN+/IN−/OUT per channel and shared VDD+/VDD− - match exactly, allowing drop-in replacement in existing layouts when upgrading to the enhanced-performance, extended-temperature, and radiation-tolerant version.
What packaging and compliance certifications apply to the TLC2274AMPWREP?
The TLC2274AMPWREP is supplied in a lead-free, RoHS-compliant TSSOP-14 (PW) package with moisture sensitivity level 3. It meets Texas Instruments' Enhanced Plastic qualification standard, including Controlled Baseline manufacturing, Extended Temperature Performance, and Enhanced Diminishing Manufacturing Sources (DMS) support - documented in TI's SGLS131B datasheet revision December 2003.
