The SC7A26 is a low-power, high-precision digital three-axis acceleration sensor IC, which features abundant functions, low power dissipation, small size, and precision measurement.
It communicates with MCU through I²C/SPI interface, the acceleration measurement data can be accessed in interrupt mode or inquiry mode. INT1 and INT2 provide many auto-detected interrupt signals which are suitable to many motion detection fields, interrupt source include 6D/4D orientation detection interrupt signal, free fall detection interrupt signal, sleep and wake up detection interrupt signal, single/multi click detection interrupt signal, step counting function interrupt signal and the hand raising function interrupt signal. A high-precision calibration module and LDO circuit are available within the IC to accurately compensate the senor’s offset error and gain error and for more stable at different voltages. It has dynamically user selectable full scales of ±2G/±4G/±8G/±16G and it is capable of measuring accelerations with output data rates from 0.78Hz to 1.6kHz.
The built-in self-test function of the chip allows the customer's system to detect the system functions during the system test, eliminating the need for complex turntable testing.
