  1. Analogue Design Amplifiers Microchip MCP6V51 MCP6V52 MCP6V54
    The analog priority amplifier shown in Figure 1 was originally conceived as part of a multiple output power supply where the voltage regulation was based on the level of the highest channel. Another application was an engine control system with an ...
