MB86437 General Description


The FUJITSU MB86437 is an AIU (audio interface unit) LSI for +3 V single-power source digital telephone devices, manufactured using CMOS process technology. The codec transmission filter characteristics meet G.712 standards, and can handle input and output in A-Law, m-Law and linear conversion modes. The MB86437 also contains the necessary DTMF, microphone and receiver amps for telephone devices.

MB86437 Maximum Ratings

Parameter Symbol Rating Unit
Min. Max.
Power supply voltage VS 0.3 6.0 V
Analog input voltage VAIN 0.3 +VS + 0.3 V
