It offers the user ease of use in single- or dual-supply systems. Built using an advance BiCMOS process, this high performance DAC is dynamically stable, capable of high current drive, and in small form factor. The applied external reference VREF determines the full-scale out- put voltage ranges from VSS to VDD, resulting in a wide selection of full-scale outputs. For multiplying and wide dynamic appli- cations, ac reference inputs can be as high as |VDD – VSS|. Two built-in precision trimmed resistors are available and can be configured easily to provide four-quadrant multiplications. A doubled-buffered parallel interface offers a fast settling time. A common level sensitive load DAC strobe ( LDAC) input allows additional simultaneous update of all DAC outputs. An external asynchronous reset ( RS) forces all registers to the zero code state when the MSB = 0 or to midscale when the MSB = 1. Both parts are offered in the same pinout and package to allow users to select the appropriate resolution for a given application without PCB layout changes. The AD5582 is well suited for DAC8412 replacement in medium voltage applications in new designs, as well as any other general purpose multichannel 10- to 12-bit applications. The AD5582/AD5583 are specified over the extended industrial (–40 ∞C to +125∞C) temperature range and offered in a thin and compact 1.1 mm TSSOP-48 package.
