Detailed Description of Hardware

The MAX5216DACLite EV kit board is loaded with the

MAX5216, Maxim’s best-in-class, lowest power, 16-bit

DAC.Theon-boardMAX6133A30provideslownoise,low

temperaturedriftof3ppm/°C,and3.000Vprecisevoltage

reference for the DAC. The MAX5216 (U1) receives a

commandfromthe16-bitMAXQ622microcontroller(U2)

through a 3-wire high-speed SPI bus. The U1 device can

run at 50MHz clock frequency, but the SPI bus speed

is limited to 6MHz on this board by the microcontroller.
