AD5582 Functional Block Diagram GENERAL DESCRIPTION The AD5582/AD5583 family of quad, 12-/10-bit, voltage output digital-to-analog converters is designed to operate from a single 5 V to 15 V or dual ±5 V supply.
It offers the user ease of use in singleor dual-supply systems.
Built using an advance BiCMOS process, this high performance DAC is dynamically stable, capable of high current drive, and in a small form factor.
The applied external reference VREF determines the full-scale output voltage ranges from VSS to VDD, resulting in a wide selection of full-scale outputs.
For multiplying and wide dynamic applications, 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 Figure 2.
