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 supply 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 single-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 package. Each device is specified for operation from -40°C to +85°C.
