92HD81B/91B Single Chip PC Audio Systems

Tempo Semiconductor 92HD81B/91B Single-Chip PC Audio Systems are low power, optimized, high fidelity, 4-channel audio codec with integrated speaker amplifier, capless headphone amplifier, and low drop out voltage regulator. The high integration of the 92HD81B enables the smallest PCB footprint with the lowest system BOM count and cost. The integrated combo jack of the Tempo Semiconductor 92HB91B allows for dual-function headphone and headset detection. Each device includes an integrated high-pass filter that allows for speaker protection. They both provide high-quality HD audio capability to notebook and business desktop PC applications.
