This paper presents the design and bench evaluation of a Class D headphone amplifier and provides compelling arguments as to why it is advantageous to use Class D, even for output powers as low as 40mW. Design tradeoffs are discussed which show how significant savings in power can be achieved at typical listening levels when compared with a conventional class AB amplifier.
