TSZ121, TSZ122, & TSZ124 Operational Amplifiers

STMicroelectronics TSZ121, TSZ122, and TSZ124 Operational Amplifiers Operational Amplifiers offer very low input offset voltages with virtually zero drift. The TSZ121 is the single version, TSZ122 the dual version, and TSZ124 the quad version, with pinouts compatible with industry standards. The TSZ121, TSZ122, and TSZ124 Op Amps offer rail-to-rail input and output, excellent speed to power consumption ratio, and 400kHz gain bandwidth product, while consuming less than 40μA at 5V. These devices also feature an ultra-low input bias current. These features make the TSZ121, TSZ122, and TSZ124 ideal for sensor interfaces, battery-powered applications, and portable applications.
