2.7V to 3.6V and 4.5V to 5.5V, Low-Power,
4-/12-Channel, 2-Wire Serial, 12-Bit ADCs
ELECTRICAL CHARACTERISTICS (continued)
(VDD = 2.7V to 3.6V (MAX1237/MAX1239), VDD = 4.5V to 5.5V (MAX1236/MAX1238), VREF = 2.048V (MAX1237/MAX1239), VREF =
4.096V (MAX1236/MAX1238), CREF = 0.1µF, fSCL = 1.7MHz, TA = TMIN to TMAX, unless otherwise noted. Typical values are at
TA = +25°C, see Tables 1–5 for programming notation.)
