    Can someone out there help me with designing of a differential amplifier that gets its supply voltage from a 9 volts battey. Its specifications are as follows;

    gain = 1 or 10
    input resistance = 1 Mohms
    output resistance = 50 ohms
    CMRR = 40 db
    Maximum input = +1 0r -1
    Maximum output= +10 or-10
    BW = 5 Mhz

    Do you need a Transistor based one or an OPAMP based one.

    Do you expect to get an output over a range of +10 volts to -10 volts with only a 9 volt source? You really need to post more details.

    Hi, Transistor based one could be alright however an alternative is not out of the question bro,

    Hi,

    I believe there is something wrong with the question I would prefer to use 12 Volts or 15 Volts. Yes the range is ± 10 Volts (limited at 0.5 Volts into 50 Ω load)
