MAX1202/MAX1203
5V, 8-Channel, Serial, 12-Bit ADCs
with 3V Digital Interface
Typical Operating Characteristics
(VDD = 5V ±5%; VL = 2.7V to 3.6V; VSS = 0V; fSCLK = 2.0MHz, external clock (50% duty cycle); 15 clocks/conversion cycle (133ksps);
MAX1202—4.7μF capacitor at REF pin; MAX1203—external reference, VREF = 4.096V applied to REF pin; TA = +25°C, unless other-
wise noted.)
