GENERAL DESCRIPTION

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.

PRODUCT HIGHLIGHTS

1. Dynamic power control for thermal management.

2. 12-bit performance.

3. Quad channel.

4. HART compliant.
