Analog Devices / Maxim Integrated MAX1032 / MAX1033 14-Bit ADCs

Analog Devices MAX1032 / MAX1033 14-bit 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 an 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 Analog Devices 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 and three differential input ranges. These ADCs are specified for operation from -40°C to +85°C and are ideal for use in industrial control systems, data-acquisition systems, avionics, and robotics.
