AD5737:  Quad Channel, 12-Bit, Serial Input, 4-20mA Output DAC with Dynamic Power Control and HART Connectivity

Product Details

Product Status:Recommended for New Designs

The AD5737 is a quad-channel 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 regulating 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.

Each channel has a corresponding CHART pin so that HART signals can be coupled onto the current output of the AD5737.

The AD5737 uses a versatile 3-wire serial interface that operates at clock rates of up to 30 MHz and is compatible with standard SPI, QSPI™, MICROWIRE®, DSP, and microcontroller interface standards. The serial interface also features optional CRC-8 packet error checking, as well as a watchdog timer that monitors activity on the interface.

For a 16 bit equivalent solution, look at the AD5757. For a voltage and current configurable version, see the AD5755, AD5755-1 or AD5735.
