MAX1043 Overview
The MAX1021/MAX1043 integrate a multichannel, 10-bit, analog-to-digital converter (ADC) and a 10-bit, digital-toanalog converter (DAC) in a single IC. The devices also include a temperature sensor and configurable generalpurpose I/O ports (GPIOs) with a 25MHz SPI™-/QSPI™-/ MICROWIRE™-patible serial interface. The ADC is available in an eight input-channel version.
