GENERAL DESCRIPTION
●The AD5755-1 is a quad, voltage and current output DAC that operates with a power supply range from −26.4 V to +33 V. Onchip dynamic power control minimizes package power dissipation in current mode. This is achieved by regulating the voltage on the output driver from 7.4 V to 29.5 V using a dc-to-dc boost converter optimized for minimum on-chip power dissipation. Each channel has a corresponding CHART pin so that HART signals can be coupled onto the current output of the AD5755-1.
