Description

The MAX1020BETX is a multichannel, 10-bit analog-to-digital converter (ADC) and an octal, 10-bit digital-to-analog converter (DAC) integrated into a single IC. It includes other features such as a temperature sensor and configurable general-purpose I/O ports (GPIOs) with a 25MHz SPI™-/QSPI™-/MICROWIRE™-compatible serial interface. This model is available in different versions with 8, 12, or 16 input channels for the ADC. The octal DAC outputs settle within 2.0µs, and the ADC has a conversion rate of 300ksps.
