说明

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 V_COM voltage 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 V_COM calibrators 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 V_COM in traditional gamma buffers such as the BUFxx702, BUFxx703, BUFxx704 and BUF11705.
