    MCU 30 Volt INTERFACE

    I am trying to source an interface IC to buffer 8 input lines on an MCU operating at 3 Volts. I need to detect when a DC voltage of 12 to 30 Volts appears on any of the lines (automotive application). Also needs EMC/ESD protection. Optocouplers not suitable, we have a discrete solution but...

    MCU Interface

    Trying to locate a single IC to interface 8 sense lines detecting +11 to +30 Volts DC appearing on them, to 8 inputs on an MCU operating on 3.3 Volts. Immunity to Electrical noise and ESD would be important. Anyone know of a suitable device?, (or am I being over optimistic). I have a discrete...

    Determining input power requirements of Audio Power Amplifiers

    Anyone have an answer on the AC input (VA)requirements for audio amps using a conventional linear PSU. For continuous RMS output normal input is 1.5 times o/p to account for transformer efficiency + heating losses etc. How much can you downrate the PSU for audio use (1000 Watts +). I've heard...
