Quad Channel, 16-Bit, Serial Input, 4-20mA & Voltage Output DAC, Dynamic Power Control, HART Connectivity
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 between 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 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.
- Dynamic power control for thermal management.
- 16-bit performance.
