Our customers would like to use the output power between 50mW and 500mW.
How much is the efficiency characteristic vary between samples? 
Could you please provide the measurement data?

    Hi, Kato-san,

    Q1. This dominated by the on-resistance of the output transistors. There is not a lot of variation in the value of these, so I would not expect much variation in efficiency from part to part.

    Q2. This is essentially flat from 20 Hz to 20 kHz.
