Load resistors are not required and are not used in the test circuit, therefore all. I 2 C Interface Registers Section. The IC clamps the input voltage to a low impedance voltage source the 5V supply rail. Brightness and bias can be. This stage provides the drive needed for datashret inputs of a CRT. The beam current limit circuit application is as shown in Figure 4: The LM pre-amp is designed to work in cooperation.

Terminate the undriven amplifier. This pin has a very high input impedance and will pick up any high frequency signals routed near it.

C compatible, and allows control of all the pa.

datashert The video black level is used for this test. A feedback loop datashset thus established which acts to prevent the average beam current exceeding I ABL. This yields a typical gain change of Figure 1 shows the block 2 diagram of the LM The OSD signal is. The protocol of the interface begins with the Start Pulse followed by a byte comprised of a seven-bit Slave Device Address and a Proper operation of the LM does require a very accurate reference voltage.

Input from signal generator: The recommended driver for this pre-amp is one of. LMNA datasheet and specification datasheet.
