AD8600APZ

Overview

The AD8600APZ is a 16-channel, 8-bit multiplying digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It features independently addressable voltage outputs with full-scale settings determined by an external reference voltage. The device utilizes a double-buffered 8-bit parallel input interface and achieves a settling time of 2 µs to ±1 LSB. Constructed using a monolithic CBCMOS process, it operates from a single +5 V supply or optional dual supplies up to ±6 V. The component is housed in a 44-lead PLCC package and supports an extended industrial temperature range of –40 °C to +85 °C.

Procurement Notes

Verify the obsolete status of the AD8600 series before procurement planning. Confirm that the PLCC-44 package availability aligns with current manufacturing schedules. Ensure that the specific APZ suffix meets the required –40 °C to +85 °C industrial temperature grade for the intended deployment environment.

Selection Notes

Select this component when multiple independent low-speed DAC channels are required within a single footprint. The device requires an external reference voltage to define the full-scale output range. Designers must account for the output swing limitation of approximately 1.0 V below VCC in single-supply configurations. Ensure the external reference can drive the typical 2 kΩ input impedance.

Part Context

The AD8600 belongs to a family of high-density multi-channel DACs designed for applications requiring synchronized updates across multiple channels. It integrates 5782 transistors on a single die. The architecture separates digital logic power (VDD1/VDD2) from analog amplifier power (VCC/VEE) to minimize noise coupling between the control interface and the analog output stages.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the datasheet marks the AD8600 as OBSOLETE, alternative components should be evaluated based on channel count, resolution, and package compatibility.
