Quad-Channel, 12-Bit, Serial Input, 4 mA to 20 mA

and Voltage Output DAC with Dynamic Power Control

Data Sheet

AD5735

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.

FEATURES

12-bit resolution and monotonicity

Dynamic power control for thermal management

Current and voltage output pins connectable to a single

terminal

Current output ranges: 0 mA to 20 mA, 4 mA to 20 mA,

and 0 mA to 24 mA

0.1% total unadjusted error (TUE) maximum

Voltage output ranges (with 20% overrange): 0 V to 5 V,

0 V to 10 V, 5 V, and 10 V

0.09% total unadjusted error (TUE) maximum

User-programmable offset and gain

On-chip diagnostics

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.

On-chip reference: 10 ppm/°C maximum

−40°C to +105°C temperature range

3. Quad channel.
