GENERAL DESCRIPTION

The MP8820 is a precision 1.6 MHz sampling 7-bit plus sign Analog-to-Digital Converter with an eight channel input mux and μP interface. The device has internal circuitry which receives the user supplied reference voltages VREF(+) and VREF(–), and generates the ADC reference voltages VMID ± (VREF(+) – VREF(–)). Since VREF(+) is internally buffered and VREF(–) is generally ground, this structure allows the user to easily generate an input range biased about a user-supplied VMID from a grounded reference source.
