DESCRIPTION The TDA9201 is a wide band video amplifier intended for high resolution monochrome or color monitors. The BRIGHTNESS and CONTRAST are DC controlled. The brightness loop includes a comparator gated by an internally generated pulse. Thanks to the contrast pre-adjust pin, this device is well suited for color application too. The output stage structure (A class current output), allows to use a very cheap high voltage amplifier using only one transistor. PIN CONNECTIONS

VCONT = 0, IBRT adjusted for having IOUT DC = 50mA outside of BLK. This parameter is not tested in production but is guaranteed by the design and qualify by means of corner lots during the qualification of the product in SGS-THOMSON. This parameter is measured on a AC testing board as described in Figure 2.
