MAX1049 Overview
The MAX1040 MAX1043/MAX1046 MAX1049 integrate a multichannel, 10-bit, analog-to-digital converter (ADC) and a quad, 10-bit, digital-to-analog converter (DAC) in a single IC. The devices also include a temperature sensor and configurable general-purpose I/O ports (GPIOs) with a 25MHz SPI™-/QSPI™-/MICROWIRE™-patible serial interface. The ADC is available in a 4 or an 8 inputchannel version.
