CYAT81689-100AA61Z Overview
It was sent with the 100-LQFP package.Devices with I²C, SPI interfaces provide better data acquisition performance.A Surface Mount-axis is mounted on the part.The circuit must be re-done if your meter does not read 1.71V ~ 1.95V, 3V ~ 5.5V for the supply voltage as this unit is designed to do.This chip should operate at -40°C ~ 85°C (TA) degrees Celsius on average.It provides a voltage reference for -.Parts requiring 20 mA supply current to function normally require current from the 20 mA supply.The official website for the Automotive, AEC-Q100, PSOC® series/family/product line contains more information.100-TQFP (14x14) supplier provided the device package.
