BUF01901 用于 Vcom 调节的基准电压生成器

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.

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.

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 VCOM in traditional gamma buffers such as the BUFxx702, BUFxx703, BUFxx704 and BUF11705
