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 onto the current output. The device uses a versatile 4-wire serial peripheral interface (SPI) that operates at clock rates of up to 50 MHz and is patible with standard SPI, QSPI™, MICROWIRE™, DSP, and microcontroller interface standards. The interface also Features an optional SPI cyclic...
