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.
