A.3.3 Description
The DAC7821 is a CMOS 12-bit current output
digital-to-analog converter (DAC). This device
operates from a single 2.5V to 5.5V power supply,
making it suitable for battery-powered and many
other applications. This DAC operates with a fast
parallel interface. Data read back allows 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 zeroes and the DAC outputs are at
zero scale. The DAC7821 offers excellent 4-quadrant
multiplication characteristics, with a large signal
multiplying and width of 10MHz. The applied

A.3.2 Applications
• Industry-Standard Pin Configuration
• 4-Quadrant Multiplication
• Portable Battery-Powered Instruments
• Analog Processing
• Waveform Generators
• Programmable Amplifiers and Attenuators
• Digitally Controlled Calibration
• Programmable Filters and Oscillators
• Composite Video
• Ultrasound
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. The
DAC7821 is available in a 20-lead TSSOP package.
