GENERAL DESCRIPTION
The AD5415
digital-to-analog converter. This device operates from a 2.5 V to
5.5 V power supply, making it suited to battery-powered appli-
cations and other applications.
As a result of being manufactured on a CMOS submicron process,
this part offers excellent 4-quadrant multiplication characteristics,
with large-signal multiplying bandwidths of 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 current-to-voltage precision amplifier.
In addition, this device contains the 4-quadrant resistors necessary
for bipolar operation and other configuration modes.
This DAC uses 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 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.
The AD5415 DAC is available in a 24-lead TSSOP package.
