Maxim Integrated MAX1343BETX

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 2.0us, and the ADC has a 225ksps conversion rate.
