General Description
The MAX1020–MAX1023/MAX1057/MAX1058 integrate a multichannel, 10-bit, analog-to-digital converter (ADC) and an octal, 10-bit, digital-to-analog converter (DAC) in a single IC. These devices also include a temperature sensor and configurable general-purpose I/O ports (GPIOs) with a 25MHz SPI™-/QSPI™-/MICROWIRE™-compatible serial interface. The ADC is available in 8/12/16 inputchannel versions. The octal DAC outputs settle within 2.0µs, and the ADC has a 300ksps conversion rate.
