GENERAL DESCRIPTION

The AD5426/AD5432/AD5443 are CMOS 8-, 10-, and 12-bit

current output digital-to-analog converters, respectively.

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.

These devices operate from a 3.0 V to 5.5 V power supply,

making them suited to battery-powered applications and many

other applications.

The AD5426/AD5432/AD5443 DACs are available in small

10-lead MSOP packages.

These DACs utilize double buffered 3-wire serial interface that

™

™,

and most

is compatible with SPI , QSPI , MICROWIRE

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

allows for daisy-chaining when multiple packages are used. Data

readback allows the user to read the contents of the DAC register

via the SDO pin. On power-up, the internal shift register and

latches are filled with 0s and the DAC outputs are at zero scale.

As a result of manufacture on a CMOS submicron process, they

offer excellent 4-quadrant multiplication characteristics, with

large signal multiplying bandwidths of 10 MHz.
