MAX1258:12-Bit, Multichannel ADCs/DACs with FIFO, Temperature Sensing, and GPIO Ports

The MAX1220/MAX1257/MAX1258 is a highly integrated system monitoring and control solution which includes a 16-channel (MAX1257/MAX1258) or 8-ch (MAX1220) 12-bit Analog to Digital Converter (ADC), twelve 12-bit Digital to Analog Converters (DACs), an internal reference, an internal temp sensor, a 4-bit (MAX1220) or 12-bit (MAX1257/MAX1258) GPIO port, and a 25MHz SPI-/QSPI™-/MICROWIRE®- compatible serial interface. The MAX1220 is available in a 36-pin TQFN package. The MAX1257/MAX1258 are available in 48-pin TQFN package. All devices are specified over the -40°C to +85°C temperature range.
