Single channel voice CODEC features enhanced performance

12 February 2003 Analogue, Mixed Signal, LSI

Winbond Electronics Corporation America offers the W6811, a single channel, dual supply voice CODEC chip claimed to feature improved performance and better sound than industry standard solutions. The chip is aimed at handset, speakerphone and telephony manufacturers migrating to 3 V designs that still require the sound quality of 5 V systems.

The W6811 features 200 nA typical power consumption in standby and power down modes. The 5 V analog interface enables the chip to maintain its long-distance line card drive capabilities while allowing design migration to lower power 3 V digital logic. This means that the user can exploit the dynamic range of 5 V signals while taking advantage of the power conservation benefits of a 3 V architecture; a key benefit for speech and telephony applications that require higher voice quality at lower power consumption. The device is offered in 24-pin packaging.
