WM8510 Datasheet

Mono CODEC with Speaker Driver


The WM8510 is a low power, high quality mono codec designed for Voice over Internet Protocol (VoIP) and Digital Telephones. The device integrates support for one pseudo-differential and one single ended input (Handset Mic and Speaker Mic) and includes drivers for speakers or headset, and mono line output, making it ideal for Telephone designs. External component requirements are reduced as no separate microphone or
earpiece amplifiers are required.
