2 / 20 page ML2280, ML2283 2 PIN CONFIGURATION NAME FUNCTION VCC Positive supply. 5V ± 10% DGND Digital ground. 0 volts. All digital inputs and outputs are referenced to this point. AGND Analog ground. The negative reference voltage for A/D converter. GND Combined analog and digital ground. CH0, Analog inputs. Digitally selected to be single VIN+, VIN– ended (VIN) or; VIN+ or VIN– of a differential input. Analog range = GND - VIN - VCC. VREF/2 Reference. The analog input range is twice the positive reference voltage value applied to this pin. V+ Input to the Shunt Regulator. DO Data out. Digital output which contains result of A/D conversion. The serial data is clocked out on falling edges of CLK. PIN DESCRIPTION ML2280 Single Differential Input 8-Pin PDIP ML2283 4-Channel MUX 14-Pin PDIP NAME FUNCTION SARS Successive approximation register status. Digital output which indicates that a conversion is in progress. When SARS goes to 1, the sampling window is closed and conversion begins. When SARS goes to 0, conversion is completed. When CS = 1, SARS is in high impedance state. CLK Clock. Digital input which clocks data in on DI on rising edges and out on DO on falling edges. Also used to generate clocks for A/D conversion. DI Data input. Digital input which contains serial data to program the MUX and channel assignments. CS Chip select. Selects the chip for multiplexer and channel assignment and A/D conversion. When CS = 1, all digital outputs are in high impedance state. When CS = 0, normal A/D conversion takes place.
