TSCS454xx中文资料Multichannel CODEC + Headphone Amp + Analog Mic数据手册Tempo规格书

描述 Description

The TSCS454xx is a low-power, high-fidelity CODEC with an integrated fixed function audio DSP targeted to consumer, professional, commercial and industrial applications such as personal audio appliances that require support for multichannel analog or digital inputs and outputs. The CODEC also integrates a filterless 3W/channel (4Ω) stereo speaker amplifier, mono earpiece amplifier / subwoofer line out, and a ground-referenced, capless stereo Class-H 40mW (16Ω) headphone amplifier.
