19-3573; Rev 1; 8/06
8-/4-Channel, ±12V Multirange Inputs,
Serial 14-Bit ADCs
General Description
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 +6V, -6V to 0, 0 to +12V,
-12V to 0, ±3V, ±6V, and ±12V), and three differential
input ranges (±6V, ±12V, ±24V).
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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
