The PCM3002 and PCM3003 are low cost single chipstereo audio CODECs (analog-to-digital and digital-toanalogconverters) with single-ended analog voltageinput and output.The ADCs and DACs employ delta-sigma modulaTIonwith 64X oversampling. The ADCs include a digitaldecimaTIon filter, and the DACs include an 8Xoversampling digital interpolaTIon filter. The DACsalso include digital attenuaTIon, de-emphasis, infinitezero detection and soft mute to form a completesubsystem. PCM3002 and PCM3003 operate withleft-justified, right-justified, or I2S data formats.PCM3002 and PCM3003 provide a power-down modethat operates on the ADCs and DACs independently.Fabricated on a highly advanced 0.6ms CMOS process,PCM3002 and PCM3003 are suitable for a widevariety of cost-sensitive consumer applications wheregood performance is required.PCM3002’s multi-functions are controlled by softwareand the PCM3003’s functions include de-emphasis,power down, and audio data format selections,which are controlled by hardware.
