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.
FEATURES • Precision 7–Bit Plus Sign ADC • 8 Channel Analog Mux • Single Reference to GND • Input Referenced to User Supplied VMID • DNL= ±1/2 LSB, INL=± 1 LSB • Single Supply: 5 V • ESD Protection: 2000 V
APPLICATIONS • Servo Control • Low Cost Audio Control • Voice Acquisition
