TS921ID

TS921ID Description

The TS921ID from STMicroelectronics is a high-performance, general-purpose operational amplifier (op-amp) designed for a wide range of analog signal conditioning applications. Housed in an 8-SOIC package, this single-channel op-amp operates over a 2.7V to 12V supply range, making it versatile for both low-voltage and standard-voltage designs. With a 4 MHz gain bandwidth product (GBW) and a 1.3V/µs slew rate, it delivers excellent dynamic performance for precision amplification tasks. The device features a low input bias current of 15 nA and a moderate input offset voltage of 3 mV, ensuring accuracy in sensitive circuits. Its 80 mA output current capability allows it to drive heavier loads compared to many general-purpose op-amps.
