MAX1343BETX+T

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.
