STMicroelectronics' TSZ12x 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 TSZ12x series offers rail-to-rail input and output, excellent speed/power consumption ratio, and 400kHz gain bandwidth product, while consuming less than 40μA at 5V. The devices also feature an ultra-low input bias current. These features make the TSZ12x family ideal for sensor interfaces, battery-powered applications and portable applications.
