LM4910 minimum output noise reduce the output power circuit


Posted on Mar 28, 2007

As shown for the LM4910 minimum output noise/reduce the output power circuit. Reduce output noise measures are: between the output terminal of a resistor in series with the loa

d Rseries, so that the output noise can be attenuated, to achieve the purpose of reducing noise; in parallel across the feedback resistor Rf frequency bypass capacitor Cf, with to suppress high frequency noise. J1 short jumper, when short jumper J1 is grounded, the amplifier is in shutdown mode, the power consumption to a minimum; when J1 short jumper off (VDD high), the amplifier is in working mode, the power PDMAX 4VDD2/2RL.
