STMicroelectronics Low Offset Voltage Op Amps

The ST precision operational amplifier portfolio includes several series covering different voltage ranges as well as multiple combinations of power consumption and gain bandwidth, allowing customers to get the best performance for the appropriate accuracy.

ST’s low precision op amp solutions include zero drift amplifiers and low offset drift over temperature range amplifiers. Thus, the precision op amps from STMicroelectronics are a perfect fit for use with any sensor such as gas, temperature, pressure, and position. Moreover, the rail-to-rail input and output feature allows easy and accurate high side and low side sensing.

The chart on the right will help customers select the best amplifier series for their needs.

 

The TS922 and TS951 are rail-to-rail BiCMOS operational amplifiers operating at up to 12 V.

Very low noise, low distortion, low offset and a high output current capability make these op amps an excellent choice for high quality, low voltage or battery operated audio systems.

The op amps’ high output current allows for low-load impedances to be driven. These TS922 and TS951 op amps are stable for capacitive loads up to 500 pF.
