My question is about the shutdown mode on these power amplifiers. Power down or power off? Why would want or need to use this shutdown feature as opposed to just cutting the power?
The data sheet (I copied from TI's Lm4871) says, "
To conserve power in portable applications, the LM4871's micropower shutdown mode (IQ = 0.6µA,
typ) is activated when VDD is applied to the SHUTDOWN pin."
