AC’97 Codecs

TSI’s STAC97xx family are general purpose, full-duplex, audio CODECs conforming to the analog component specification of AC’97 (Audio Codec 97 Component Specification Rev. 2.2 or Rev 2.3). The STAC97xx incorporate TSI’s proprietary ΣΔ technology to achieve Line-In to Line-Out performance in excess of 94dB. For your redesign of your Industrial / IoT / Embedded PC design, trust that Tempo will continue to serve the AC’97 market for years to come.
