DA7211 Datasheet PDF

DA7211 Ultra-low power stereo codec Company confidential General description DA7211 features a high fidelity and powerful 72 mW per channel headphone amplifier. The device may be operated from a single 1.8 V supply. Total device consumption is only 2.5 mW which helps extend music playback time for battery operated equipment. The fully integrated fractional PLL has been designed to use minimal power while supporting a wide range of input and output frequencies. Internal suppression circuits help maintain audio synchronisation in the presence of system noise on the external clock. Six analogue input pins allow multiple audio sources to be internally mixed, eliminating the need for external switches. Both single-ended and fully-differential line and microphone inputs are supported with built-in variable gain amplifiers to optimise the dynamic range prior to digitisation. This provides hardware support for ambient noise cancellation.
