GENERAL DESCRIPTION
The AD5735 is a quad-channel 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 reduced power dissipation
is achieved 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.
The AD5735 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.
