STMicroelectronics Low Power Op Amps

The ST low power op amp portfolio includes several series covering different voltage ranges as well as multiple combinations of power consumption and gain bandwidth, providing the optimal performance for the appropriate power budget.

ST’s low power operational amplifier solutions include widely used devices, but also provide design engineers with upgrade options such as better accuracy, a stand-by feature and small packaging offering.

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

 

The TSV9 operational amplifiers from ST offer low voltage operation and rail-to-rail input and output, as well as an excellent speed/power consumption ratio. The TSV9 op amps offer 8 MHz (TSV91) to 20 Mhz (TSV99) gain-bandwidth options while consuming only 1.1 mA maximum at 5 V. The op amps also feature an ultra-low input bias current.

The TSV9 devices are ideal for sensor interfaces, battery-supplied and portable applications, as well as active filtering.
