GENERAL DESCRIPTION

The AD5429/AD5439/AD5449¹are CMOS 8-, 10-, and 12-bit

dual-channel current output digital-to-analog converters,

respectively. These devices operate from a 2.5 V to 5.5 V power

supply, making them suited to battery-powered and other

applications.

Analog processing

Instrumentation applications

Programmable amplifiers and attenuators

Digitally controlled calibration

Programmable filters and oscillators

Composite video

The applied external reference input voltage (V_REF) determines

the full-scale output current. An integrated feedback resistor

(R_FB) provides temperature tracking and full-scale voltage

output when combined with an external current-to-voltage

precision amplifier.

Ultrasound

Gain, offset, and voltage trimming

These DACs utilize a double-buffered, 3-wire serial interface

that is compatible with SPI®, QSPI™, MICROWIRE™, and most

DSP interface standards. In addition, a serial data out pin (SDO)

allows daisy-chaining when multiple packages are used. Data

readback allows the user to read the contents of the DAC

are at zero scale.

As a result of manufacture on a CMOS submicron process,

these parts offer excellent 4-quadrant multiplication character-

istics, with large signal multiplying bandwidths of 10 MHz.

The AD5429/AD5439/AD5449 DAC are available in 16-lead

TSSOP packages.
