The TLC227x series is a dual and quadruple operational amplifier from Texas Instruments, with rail-to-rail output performance for single- or split-supply applications. The series offers 2 MHz of bandwidth and 3 V/µs of slew rate, with better noise, input offset voltage, and power dissipation than existing CMOS operational amplifiers. The TLC227x has a noise voltage of 9 nV/√Hz, which is two times lower than competitive solutions.
The document describes the TLC227x and TLC227xA families of Advanced LinCMOS™ RAIL-TO-RAIL OPERATIONAL AMPLIFIERS. These devices feature low input offset voltage, low noise (9 nV/VHz Typ), and high-gain bandwidth (2.2 MHz Typ). They are designed for both single-supply and split-supply operation with rail-to-rail output swing.
The datasheet provides absolute maximum ratings, recommended operating conditions, and detailed electrical characteristics tables for various package suffixes (C, AC, ID, AQD, etc.). It also includes pin configuration diagrams and notes on production data and standard warranty.
