Resistor Network Fits PC Audio Uses

Providing the components necessary for signal conditioning of analog audio inputs for AC97-compliant codecs, as well as the gain setting resistors for headphone and microphone amplifiers, PACAC97 resistor network offers 6 dB of attenuation to 1 V_RMS for LINE-IN, AUX and CD inputs. The CD line level inputs have an additional ground signal, CD_GND, that supports pseudo-differential amplifiers present in AC97 codecs to handle attenuation of common-mode ground noise typically present at the output of CD ROM drives. Attenuating the CD inputs produces a higher quality CD signal. The network is also said to provide exceptional inter-channel and channel-to-channel crosstalk attenuation necessary for high quality audio.
