ANALOG DEVICES AD8522ARZ Digital to Analogue Converter, 12 bit, 3 Wire, Serial, 4.5V to 5.5V, NSOIC, 14 Pins

AD8522 is a complete dual 12bit, single-supply, voltage output DAC. Fabricated in a CBCMOS process, features include a serial digital interface, onboard reference, and buffered voltage output. Ideal for +5V-only systems, this monolithic device offers low cost and ease of use, and requires no external components to realize the full performance of the device. The serial digital interface allows interfacing directly to numerous microcontroller ports, with a simple high speed, three-wire data, clock, and load strobe format. The 16bit serial word contains the 12bit data word and DAC select address, which is decoded internally or can be decoded externally using LDA, LDB (active low) inputs. A serial data output allows the user to easily daisy-chain multiple devices in conjunction with a chip select input. Application includes digitally controlled calibration, servo controls, process control equipment, computer peripherals, portable instrumentation cellular base stations voltage adjustment.
