FEATURES  
DESCRIPTION  
2.7 V to 5.5 V Supply Operation  
The DAC7811 is a CMOS 12-bit current output  
digital-to-analog converter (DAC). This device  
operates from a 3.0 V to 5.5 V power supply, making  
it suitable to both battery-powered and many other  
applications.  
50 MHz Serial Interface  
10 MHz Multiplying Bandwidth  
±10 V Reference Input  
Low Glitch Energy: 2 nV-s  
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 for  
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 zeroes  
and the DAC outputs are at zero scale.  
Extended Temperature Range:  
–40°C to +125°C  
10-Lead SON Package  
12-Bit Monotonic  
4-Quadrant Multiplication  
Power-On Reset with Brownout Detection  
Daisy-Chain Mode  
The DAC7811 offers excellent 4-quadrant multipli-  
cation characteristics, with large signal multiplying  
bandwidth of 10 MHz. The applied external reference  
input voltage (VREF) determines the full-scale output  
current. An integrated feedback resistor (RFB) pro-  
vides temperature tracking and full-scale voltage  
output when combined with an external cur-  
rent-to-voltage precision amplifier.  
Readback Function  
Industry-Standard Pin Configuration  
APPLICATIONS  
Portable Battery-Powered Instruments  
Waveform Generators  
Analog Processing  
Programmable Amplifiers and Attenuators  
Digitally Controlled Calibration  
Programmable Filters and Oscillators  
Composite Video  
The DAC7811 is available in a 10-lead MSOP pack-  
age as well as a small 10-lead SON package.
