TS274CN

TS274CN Description

The TS274CN from STMicroelectronics is a quad CMOS operational amplifier designed for precision analog applications. Packaged in a 14-pin DIP (Tube), this IC operates over a 3V to 16V supply range, making it versatile for both low and moderate voltage systems. With a 3.5 MHz gain bandwidth product and 5.5V/µs slew rate, it delivers high-speed performance while maintaining low power consumption (1mA supply current). Its 1 pA input bias current and 1.1 mV input offset voltage ensure accuracy in signal conditioning. The TS274CN is RoHS3 compliant and REACH unaffected, meeting modern environmental standards despite its obsolete status.
