WT9101

The WT9101 pre-amp is an integrated CMOS CRT pre-amp. The IC is I²C compatible, and allows control of all the parameters necessary to directly setup and adjust the gain and contrast in the CRT display. Brightness and bias can be controlled through the DAC outputs. Black level clamping of the signal is carried out directly on the AC coupled input signal into the high impedance preamplifier input, thus eliminating the need for the additional black level clamp capacitors. The WT9101 is packaged in an industry standard 24-lead DIP molded plastic package.
