12-Bit, Multichannel ADCs/DACs with FIFO, Temperature Sensing, and GPIO Ports
General Description
The MAX1220–MAX1223/MAX1257/MAX1258 integrate a 12-bit, multichannel, analog-to-digital converter (ADC), and a 12-bit, octal, 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. All devices include an internal reference (2.5V or 4.096V) for both the ADC and DAC. Programmable refwww.DataSheet4U.
