19-3573; Rev 4; 8/11 8- and 4-Channel, ±3 x VREF Multirange Inputs, Serial 14-Bit ADCs General Description Features M The MAX1032/MAX1033 multirange, low-power, 14-bit, Software-Programmable Input Range for Each A Channel X successive-approximation, analog-to-digital converters (ADCs) operate from a single +5V supply and achieve Single-Ended Input Ranges (VREF = 4.096V) throughput rates up to 115ksps. A separate digital sup- (0 to (3 x VREF)/2, (-3 x VREF)/2 to 0, 1 ply allows digital interfacing with 2.7V to 5.25V systems 0 to 3 x VREF, -3 x VREF to 0, (±3 x VREF)/4, 0 using the SPI™-/QSPI™-/MICROWIRE™-compatible (±3 x VREF)/2, ±3 x VREF) 3 2 serial interface. Partial power-down mode reduces the Differential Input Ranges supply current to 1.3mA (typ). Full power-down mode / (±3 x VREF)/2, 3 x VREF, ±6 x VREF reduces the power-supply current to 1µA (typ).
