Overview
The AD5755ACPZ-REEL7, produced by Analog Devices Inc., is a quad, voltage and current output digital-to-analog converter (DAC). This component is designed to operate with a wide power supply range from -26.4 V to +33 V, making it versatile for various industrial and control applications. The AD5755 features on-chip dynamic power control, which minimizes package power dissipation in current mode through a dc-to-dc boost converter. This converter regulates the voltage on the output driver from 7.4 V to 29.5 V, optimizing for minimum on-chip power dissipation. The device is packaged in a 64-lead LFCSP (Lead Frame Chip Scale Package) with an exposed pad, enhancing thermal performance and reducing the overall footprint.
