The AD8522 is a complete dual 12-bit, single-supply, voltage output DAC in a 14-pin DIP, or SO-14 surface mount package. Fabricated in a CBCMOS process, features include a serial digital interface, onboard reference, and buffered voltage output. Ideal for +5 V-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 16-bit serial word contains the 12-bit data word and DAC select address, which is decoded internally or can be decoded externally using inputs. A serial data output allows the user to easily daisy-chain multiple devices in conjunction with a chip select input. A reset RS input sets the outputs to zero scale or midscale, as determined by the input MSB. The output 4.095 V full scale is laser trimmed to maintain accuracy over the operating temperature range of the device, and gives the user an easy-to-use one-millivolt-per-bit resolution. A 2.5 V reference output is also available externally for other data acquisition circuitry, and for ratiometric applications. The output buffers are capable of driving ±5 mA. The AD8522 is available in the 14-pin plastic DIP and low profile 1.5 mm SOIC-14 packages.
