Programming of the output occurs through an industry-standard, two-wire serial interface. Once the correct V 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 100m A), the BUF01900 and BUF01901 are ideally suited as programmable V 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 in traditional gamma buffers such as the BUFxx702, BUFxx703, BUFxx704 and BUF11705. 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 puters. Both devices are specified from - 40°C to +85°C.
