TSZ121IYCT

Instrumentation, Op Amps, Buffer Amps Overview

The TSZ121IYCT is a single-channel, zero-drift operational amplifier from the TSZ12x series by STMicroelectronics. It features a maximum input offset voltage of 5 µV at 25 °C and 8 µV across the full temperature range (-40 °C to 125 °C). The device operates on a supply voltage between 1.8 V and 5.5 V with a gain-bandwidth product of 400 kHz. Power consumption is less than 40 µA at 5 V. It supports rail-to-rail input and output, offers an ultra-low input bias current of 600 pA, and has a slew rate of 0.17 V/µs. The component is AEC-Q100 qualified and housed in an SC70-5 package.
