Dual, 8-Bit,
Voltage-Output Serial DAC in 8-Pin SOT23
General Description
The MAX5222 contains two 8-bit, buffered,
voltage-output digital-to-analog converters (DAC A and DAC B) in a small 8-pin SOT23 package.
Both DAC outputs can source and sink 1mA to within 100mV of ground and VDD.
The MAX5222 operates with a single +2.
7V to +5.
5V supply.
The device uses a 3-wire serial interface, which operates at clock rates up to 25MHz and is compatible with SPI™, QSPI™, and MICROWIRE™ interface standards.
The serial input shift register is 16 bits long and consists of 8 bits of DAC input data and 8 bits for DAC selection and shutdown control.
DAC registers can be loaded independe...
