The MAX1032/MAX1033 multirange, low-power, 14-bit,
successive-approximation, analog-to-digital converters
(ADCs) operate from a single +5V supply and achieve
throughput rates up to 115ksps. A separate digital sup-
ply allows digital interfacing with 2.7V to 5.25V systems
using the SPI™-/QSPI™-/MICROWIRE™-compatible
serial interface. Partial power-down mode reduces the
supply current to 1.3mA (typ). Full power-down mode
reduces the power-supply current to 1µA (typ).
The MAX1032 provides eight (single-ended) or four
(true differential) analog input channels. The MAX1033
provides four (single-ended) or two (true differential)
analog input channels. Each analog input channel is
independently software programmable for seven sin-
gle-ended input ranges 0 to (3 x V
to 0, 0 to 3 x V
(±3 x V
ranges (±3 x V
An on-chip +4.096V reference offers a small convenient
ADC solution. The MAX1032/MAX1033 also accept an
external reference voltage between 3.800V and 4.136V.
The MAX1032 is available in a 24-pin TSSOP package
and the MAX1033 is available in a 20-pin TSSOP pack-
age. Each device is specified for operation from -40°C
to +85°C.
