Programmable Voltage Source  
with Memory  
FD EATURES  
DESCRIPTION  
The BUF01900 and BUF01901 provide a programmable  
voltage output with 10-bit resolution. Programming of the  
output occurs through an industry-standard, two-wire  
serial interface. Once the correct VCOM voltage is  
established it can easily be stored into the integrated  
nonvolatile memory.

LOW SUPPLY CURRENT: 900µA  
SUPPLY VOLTAGE: 7V to 18V  
DIGITAL SUPPLY: 2.0V to 5.5V  
An initial output voltage and adjustment range can be set  
by an external resistor-divider. With its large output current  
capability (up to 100mA), the BUF01900 and BUF01901  
are ideally suited as programmable VCOM calibrators in  
LCD panels.  
INDUSTRY-STANDARD, TWO-WIRE  
INTERFACE  
The BUF01901 has the digital-to-analog converter (DAC)  
output brought out directly. It has a slightly lower cost than  
the BUF01900, and works very well with the integrated

The BUF01900 and BUF01901 are both available in  
TSSOP-8 and 3mm x 3mm DFN-10 packages. The  
DFN-10 package (only 0.9mm in height) is especially  
well-suited for notebook computers. Both devices are  
specified from −40°C to +85°C.
