EVAL-AD5422EBZ 数据手册

Single Channel, 12-/16-Bit, Serial Input,

Current Source and Voltage Output DACs

AD5412/AD5422

FEATURES

GENERAL DESCRIPTION

12-/16-bit resolution and monotonicity

The AD5412/AD5422 are low-cost, precision, fully integrated

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

0 mA to 24 mA

12-/16-bit digital-to-analog converters (DAC) offering a pro-

grammable current source and programmable voltage output

designed to meet the requirements of industrial process control

applications.

0.01 ꢀ FSR typical total unadjusted error (TUE)

3 ppm/°C output drift

Voltage output ranges: 0 V to 5 V, 0 V to 10 V, 5 V, 10 V

10ꢀ overrange

The output current range is programmable at 4 mA to 20 mA,

0 mA to 20 mA, or an overrange function of 0 mA to 24 mA.

0.01 ꢀ FSR typical total unadjusted error (TUE)

2 ppm/°C output drift

Flexible serial digital interface

On-chip output fault detection

On-chip reference: 10 ppm/°C maximum

Asynchronous clear function

Power supply range

AV_DD: 10.8 V to 40 V

AV_SS: −26.4 V to −3 V/0 V

Voltage output is provided from a separate pin that can be

configured to provide 0 V to 5 V, 0 V to 10 V, 5 V, or 10 V

output ranges; an overrange of 10% is available on all ranges.

Analog outputs are short and open-circuit protected and can

drive capacitive loads of 1 μF.

The device operates with an AV_DDpower supply range from

10.8 V to 40 V. Output loop compliance is 0 V to AV_DD– 2.5 V.

The flexible serial interface is SPI- and MICROWIRE™-

compatible and can be operated in 3-wire mode to minimize

the digital isolation required in isolated applications.

Output loop compliance: AV_DD– 2.5 V

Temperature range: −40°C to +85°C

TSSOP and LFCSP packages

The device also includes a power-on-reset function, ensuring

that the device powers up in a known state. The part also

includes an asynchronous clear pin (CLEAR) that sets the

outputs to zero-scale/midscale voltage output or the low

end of the selected current range.

APPLICATIONS

Process control

Actuator control

PLC

The total output error is typically 0.01% in current mode and

0.01% in voltage mode.
