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. On-
chip 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.
The part uses a versatile 3-wire serial interface that operates at
clock rates of up to 30 MHz and is compatible with standard
SPI, QSPI, MICROWIRE, DSP, and microcontroller interface
standards. The interface also features optional CRC-8 packet
error checking, as well as a watchdog timer that monitors
activity on the interface.
