32-lead, 5 mm × 5 mm LFCSP package The AD5758 is a single-channel, voltage and current output digitalto-analog converter (DAC) that operates with a power supply range
from −33 V (minimum) on AVSS to +33 V (maximum) on AVDD1
with a maximum operating voltage between the two rails of 60 V.
On-chip dynamic power control (DPC) minimizes package power
dissipation, which is achieved by regulating the supply voltage
(VDPC+) to the VIOUT output driver circuitry from 5 V to 27 V using
a buck dc-to-dc converter, optimized for minimum on-chip power
dissipation. The CHART pin enables a HART® signal to be coupled …
