Dual, 8-Bit, Voltage-Output Serial DAC in 8-Pin SO Package
_______________General Description
The MAX522 contains two 8-bit, buffered, voltage-output digital-to-analog converters (DAC A and DAC B) in small 8-pin SO and DIP packages. DAC A’s buffer can source and sink 5mA, and DAC B’s output can source and sink 500µA, both to within 0.5V of ground and V DD. The MAX522 operates with a single +2.7V to +5.5V supply. The device utilizes a 3-wire serial interface, which operates at clock rates up to 5MHz and is compatible with SPI™, QSPI™, and Microwire™ interface standards. The serial input shift register is 16 bits long and consists of eight bits of DAC input data and eight bits for DAC selection and shutdown control.
