Description
General part information
BUF01900 Series
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 VCOMvoltage is established it can easily be stored into the integrated nonvolatile memory.
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 VCOMcalibrators in LCD panels.
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 VCOMin traditional gamma buffers such as the BUFxx702, BUFxx703, BUFxx704 and BUF11705.
