AD5755-1ACPZ

AD5755-1 is a quad, voltage and current output digital-to-analog converter (DAC) that operates with a power supply range from -26.4V to +33V. On-chip dynamic power control minimizes package power dissipation in current mode. This is achieved by regulating the voltage on the output driver from 7.4V to 29.5V 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 device 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. Application includes process control, actuator control, programmable logic controllers (PLCs), HART network connectivity.
