BUF01900AIPWG4 [Texas Instruments]

The BUF0190x family consists of a 10-bit digital-to-analog converter (DAC) with on-chip nonvolatile memory that stores DAC values for power-up initialization. The BUF01900 includes an integrated voltage buffer capable of driving high currents up to 100mA, while the BUF01901 is a lower-cost version without the buffer, designed to work with external gamma buffers. Both devices feature rail-to-rail output, low supply current, and are optimized for VCOM calibration in LCD panels. They support programming through a two-wire interface and offer programmable output voltage with external resistor-divider adjustment.
