AD5753 Single-Channel Digital-to-Analogue Converter

Analog Devices AD5753 Single-Channel Digital-to-Analogue Converter (DAC) operates with a power supply range from a minimum of −33V on AV_SS to a maximum of +33V on AV_DD1. This is done with a maximum operating voltage of 60V between the two rails. On-chip dynamic power control (DPC) minimises package power dissipation. This minimisation is achieved by using buck dc-to-dc converters optimised for minimum on-chip power dissipation to regulate the voltage (V_DPC+ and V_DPC−). That voltage is sent to the VI_OUT output driver circuitry from the ±5V to ±27V supply voltage. The C_HART pin enables a Highway Addressable Remote Transducer® (HART) signal to be coupled on the current output.
