Cirrus Logic WM8962BECSN/R

Стереофонический звукI²C, SPI24 b2 / 2-40°C ~ 85°C

Overview

The WM8962/62B are low power, high performance stereo codecs featuring an integrated charge pump to provide a ground referenced output which removes the need for DC blocking capacitors on the headphone outputs and incorporates a dual-mode charge pump architecture to optimize efficiency and power consumption during playback. A DC Servo is used to reduce DC ground offsets and to improve power consumption and minimizes pops and clicks. Stereo Class D speaker drivers provide 2W per channel into 4Ω BTL loads, with a 5V supply. Low leakage, excellent PSRR and pop/click suppression mechanisms also allow direct battery connection to the speaker supply. Flexible speaker boost settings allow speaker output power to be maximized while minimizing other analog supply currents. Control sequences for audio path setup can be pre-loaded and executed by an integrated sequencer to reduce software driver development and eliminate pops and clicks via Cirrus Logic’s SilentSwitch™ technology. Flexible input configuration: four stereo inputs or eight mono inputs on Left or Right ADC, with a complete analog (four single-ended stereo inputs) and digital microphone interface. A programmable audio enhancement DSP is included with multiple preset algorithms. Virtual surround sound widens the stereo speaker audio image, HD Bass enhances low frequencies, and ReTune™ flattens the frequency response of the speaker or microphone path. A configurable DSP includes additional functions such as 3D widening for recording, a 5-band parametric EQ and Dynamic Range Controller.
