DESCRIPTION
Ultra-low power and low noise interfaces to many other audio components in the system are provided. A powerful 1W speaker driver can operate in class D or AB modes, providing total flexibility to the system designer. Low leakage, high PSRR and pop/click suppression enable direct battery connection for the speaker supply. A very highly flexible input configuration supports multiple microphone or line inputs (mono or stereo, single-ended or differential). Four headphone drivers support fully differential headset drive, providing excellent crosstalk performance and bass response, maximising stereo effects, and allowing the removal of large and expensive headphone capacitors. Stereo 24-bit sigma-delta ADCs and DACs provide hi-fi quality audio record and playback, with a flexible digital audio interface supporting most commonly-used clocking schemes. An integrated low power PLL, an alternative DAC interface and TDM support provide additional flexibility. WM8991 FEATURES
