MAX187/ MAX189
+5V, Low-Power, 12-Bit Serial ADCs
ELECTRICAL CHARACTERISTICS (continued)
(VDD = +5V ±5%; VGND = 0V; unipolar input mode; 75ksps, fCLK = 4.0MHz, external clock (50% duty cycle); MAX187—internal refer-
ence: VREF = 4.096V, 4.7µF capacitor at REF pin, or MAX189—external reference: VREF = 4.096V applied to REF pin, 4.7µF capacitor
at REF pin; TA = TMIN to TMAX; unless otherwise noted.)
