GENERAL DESCRIPTION
The AD5428/AD5440/AD54471 are CMOS, 8-, 10-, and 12-bit,
dual-channel, current output digital-to-analog converters (DACs),
respectively. These devices operate from a 2.5 V to 5.5 V power
supply, making them suited to battery-powered and other
applications.
As a result of being manufactured on a CMOS submicron process,
they offer excellent 4-quadrant multiplication characteristics,
with large signal multiplying bandwidths of up to 10 MHz.
The DACs use data readback, allowing the user to read the
contents of the DAC register via the DB pins. On power-up, the
internal register and latches are filled with 0s, and the DAC
outputs are at zero scale.
The applied external reference input voltage (VREF) determines
the full-scale output current. An integrated feedback resistor (RFB)
provides temperature tracking and full-scale voltage output when
combined with an external I-to-V precision amplifier.
The AD5428 is available in a small 20-lead TSSOP package, and
the AD5440/AD5447 DACs are available in small 24-lead TSSOP
packages.
