• Manufacturer Part Number: TEA6880
• Description: Up-level Car radio Analog Signal Processor CASP
• Manufacturer: Philips Semiconductors

10 CHARACTERISTICS
FM part: input signal V
FM audio measurements are taken at pins 13 and 27.
Tone part: R
attenuator = 0 dB; loudness = 0 dB, off; volume 2 attenuators = 0 dB; bass linear; treble linear; input voltage = 1 V, f = 1 kHz. Tone part audio
measurements are taken at pins 33 and 37. V
This IC shall not radiate noise in the audio system such that it disturbs any other circuit. This IC shall also not be susceptible to the radiation of any
other circuit.
