Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

AMC7891SRHH is a highly-integrated, low-power, complete analog monitoring and control system in a very small package.

For monitoring functions, the AMC7891 has 8 uncommitted inputs multiplexed into a 10-bit SAR analog-to-digital converter (ADC) and an accurate on-chip temperature sensor. Control signals are generated through four, independent, 10-bit digital-to-analog converters (DACs). Additional digital signal monitoring and control is accomplished through twelve configurable GPIOs. An internal reference can be used to drive the ADC and DACs.
