AD5757 Quad Channel, 16-Bit, Serial Input, 4-20mA Output DAC, Dynamic Power Control, HART Connectivity
The AD5757 is a quad, current output DAC that operates with a power supply range from 10.8 V to 33 V. On-chip dynamic power control minimizes package power dissipation by regulat-ing the voltage on the output driver from 7.4 V to 29.5 V using a dc-to-dc boost converter optimized for minimum on-chip power dissipation.
Dynamic power control for thermal management.
16-bit performance.
Multichannel.
HART Compliant.
Each channel has a corresponding CHART pin so that HART signals can be coupled onto the current output of the AD5757.
The part uses a versatile 3-wire serial interface that operates at
clock rates up to 30 MHz and that 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.
