GENERAL DESCRIPTION
The AD5452W is a CMOS 12-bit current output digital-to-analog
converter. This device operates from a 2.5 V to 5.5 V power supply,
making it suited to several applications, including battery-
powered applications.
As a result of manufacture on a CMOS submicron process, this
DAC offers excellent four-quadrant multiplication characteris-
tics of up to 12 MHz.
This DAC utilizes a double-buffered, 3-wire serial interface that
is compatible with SPI, QSPI™, MICROWIRE™, and most DSP
interface standards. Upon power-up, the internal shift register
and latches are filled with 0s, and the DAC output is at zero scale.
The applied external reference input voltage (VREF) determines
the full-scale output current. This part can handle ±10 V inputs
on the reference, despite operating from a single-supply power
supply of 2.5 V to 5.5 V. An integrated feedback resistor (RFB)
provides temperature tracking and full-scale voltage output
when combined with an external current-to-voltage precision
amplifier.
The AD5452W DAC is available in an 8-lead MSOP package.
