GENERAL DESCRIPTION
The AD54151 is a CMOS, 12-bit, dual-channel, current output
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 (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 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. The
EV-AD5415/49SDZ evaluation board is available for evaluating
DAC performance. For more information, see the UG-296
evaluation board user guide.
