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. This device also features an ultra-low input bias current. These features make the TSZ12x family ideal for sensor interfaces, battery-powered applications and portable applications. Typical applications include battery-powered applications, portable devices, signal conditioning and medical instrumentation.
