Maxim Integrated MAX1346BETX T

Description
The MAX1340/MAX1342/MAX1346/MAX1348 integrate a multichannel, 12-bit analog-to-digital converter (ADC) and a quad, 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 4 or an 8 input-channel version. The four DAC outputs settle within 2.0us, and the ADC has a 225ksps conversion rate.
