19-4010; Rev 1; 12/07 EVAALVUAAILTAIOBNLEKIT 12-Bit, Multichannel ADCs/DACs with FIFO, Temperature Sensing, and GPIO Ports MAX1221/MAX1223/MAX1343 General Description The MAX1221/MAX1223/MAX1343 integrate a multichannel, 12-bit, analog-to-digital converter (ADC) and a 12-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™-compatible serial interface. The ADC is available in a 12 or an eight input-channel version. The DAC outputs settle within 2.0µs, and the ADC has a 225ksps conversion rate. All devices include an internal reference (2.5V) providing a well-regulated, low-noise reference for both the ADC and DAC.
