WebFeb 13, 2005 · If you are using the magnetic pick-up input (green and violet wires) to trigger your MSD Ignition, you will need the PN 8920 tach adapter. The PN 8920 will correct the operation of most voltage-triggered tachometers that do not work directly off the tach output terminal of the MSD control. This adapter should also be used on current-triggered ... Web• A differential amplifier circuit will filter undesirable noise via the common-mode-rejection-ratio (CMRR) of the amplifier. • A resistive network can be used to reduce the voltage at the amplifier’s input terminals. For example, if R IN = R*, the input voltage will be reduced in half and the amplifier will be biased at VS/2. Note that ...
