FEATURES

GENERAL DESCRIPTION

16/12-Bit Resolution and Monotonicity

Dynamic Power Control for Thermal Management

IOUT Range: 0mA-20mA, 4mA–20mA or 0mA–24mA

0.05% Total Unadjusted Error (TUE) Max

User programmable Offset and Gain

On Chip Diagnostics

The AD5757/AD5737 is a quad, current output DAC, which

operates with a power supply of up to +33v. On chip dynamic

power control minimizes package power dissipation in current

mode. This is achieved by regulating the voltage on the output

driver from between 7V-30V.

Each channel has a corresponding CHART pin so that HART

signals can be coupled onto the AD5757/AD5737’s current

output.

On-Chip Reference ( 5 ppm/°C Max)

−40°C to +105°C Temperature Range

APPLICATIONS

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.
