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.

The DA7211 provides two volume-controlled differential/single-ended stereo line-out drivers and

ground-centred stereo amplifiers to directly drive standard 3-wire 16 Ω headphones. For example the

dc coupled, dedicated pop-free drivers may be connected simultaneously to stereo headphones,

stereo speakers and a mono line out without external switches.

All filtering functions are performed digitally including 5-band EQ and a digital input AGC with

programmable attack and decay parameters. A configurable signal processing engine allows various

audio enhancements and effects such as acoustic filtering, transducer equalisation, wind noise

suppression and 3D sound

The multi-slot I2S/PCM interface supports all common sample rates between 8 and 96 kHz in master

or slave mode operation.
