GENERAL DESCRIPTION
The AD5405
digital-to-analog converter (DAC). This device operates from a
2.5 V to 5.5 V power supply, making it suited to battery-powered
and other applications.
As a result of manufacture with a CMOS submicron process, the
device offers excellent 4-quadrant multiplication characteristics,
with large signal multiplying bandwidths of up to 10 MHz.
The applied external reference input voltage (V
the full-scale output current. An integrated feedback resistor (R
provides temperature tracking and full-scale voltage output when
combined with an external I-to-V precision amplifier. This device
also contains the 4-quadrant resistors necessary for bipolar
operation and other configuration modes.
This DAC uses 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 AD5405 has a 6 mm × 6 mm, 40-lead LFCSP package.
