18-Bit, Single-Channel, Ultra-Low Power, Delta-

Sigma ADC with 2-Wire Serial Interface

Electrical Characteristics (continued)

(VAVDD = +3.6V, VDVDD = +1.8V, VREFP - VREFN = VAVDD; internal clock, TA = TMIN to TMAX, unless otherwise noted. Typical values

are at TA = +25°C under normal conditions, unless otherwise noted.)
