AD5758BCPZ

AD5758 is a single-channel, voltage and current output digital-to-analogue converter with dynamic power control and HART connectivity that operates with a power supply range from -33V (mini) on AVSS to +33V (max) on AVDD1 with a maximum operating voltage between the two rails of 60V. On-chip dynamic power control minimizes package power dissipation, which is achieved by regulating the supply voltage to the VIOUT output driver circuitry from 5 to 27V using a buck dc-to-dc converter, optimized for minimum on-chip power dissipation. The device uses a versatile 4wire serial peripheral interface that operates at clock rates of up to 50MHz and is compatible with standard SPI, QSPI™, MICROWIRE™, DSP, and microcontroller interface standards. Application includes process control, actuator control, channel isolated analogue outputs, programmable logic controller and distributed control systems applications, HART network connectivity.
