AK8996W

[AK8996/W] AK8996/W Pressure Sensor Interface IC The AK8996 is a pressure sensor interface IC that features compensation for temperature drift and sensor variation. It is designed to excite and interface to a bridge sensor. Variations in the sensor can be corrected via compensation values stored in integrated non-volatile memory (EEPROM). Compensation values are obtained from measurement results for a set of offset voltages and temperature drift, along with a set of bridge voltages and temperature drift, including characteristics of the AK8996. The AK8996 is available in either a 16-pin QFN package or in wafer form.
