Zero-drift op-amps

25 June 2014 Analogue, Mixed Signal, LSI

STMicroelectronics’ TSZ121 family of zero-drift op-amps deliver high performance in popular packages and small-outline alternatives, suitable for Internet-of-Things (IoT) or wearable-device applications including temperature sensors, wellness and fitness monitors, and automotive controls. With input-offset voltage of 5 μV at 25°C and temperature stability of 30 nV/°C, these chopper-stabilised op-amps are ideal for front-end signal conditioning or low-side current measurement. Their high precision guarantees accuracy without trimming, while ultra-low temperature drift prevents system performance degradation at higher temperature without requiring self-calibration.
