ROHM Semiconductor Automotive Audio Processor ICs

ROHM Semiconductor Automotive Audio Processor ICs are available in SMD 24 and 40-pin types, higher voltage ranges of 7V to 9.5V, and I2C bus interface. These audio processor ICs offer low distortion and noise voltage, and some feature "advanced switch circuits." The automotive audio processor ICs-specific technology reduces switching noise between bands and inputs in-car audio systems. These audio processor ICs are offered in SSOP-B28 and SSOP-B40 package types. The audio processor ICs feature bass, middle, and treble tone control bands, 1-channel mixing, and 3 and 6 outputs. These processor ICs operate at -40°C to 85°C temperature range. Applications include car audio, audio equipment of mini compo, micro compo, and TV.
