1 General Description
iSentek IST8310 is a 3-axis digital magnetometer with 3.0x3.0x1.0mm3, 16-pin LGA package. It is an integrated chip with 3-axis magnetic sensors, digital control logic, built-in temperature compensation circuit and self-test function. IST8310 provides an I2C digital output with fast mode up to 400kHz. The high output data rate, ultra-low hysteresis, excellent temperature drift and low noise performance feathers make it a perfect candidate for high accuracy applications.
