AN6141S

AN6141S is compander ICs for cordless telephones incorporating standby and received-signal amplifying functions.Their noise compressor circuit has such an improved linearity as to remarkably reduce radio transmission noise.These ICs provide a cordless telephone with a high-quality transmission performance.There are some features as follows.First is compander IC designed for cordless telephones.Secondly,the noise compressor circuit has an improved linearity of 10 dB.Besides,the compressor/expander circuitry incorporates preamplifiers to make level and frequency adjustments easier.Furthermore,the standby circuit provides for a low-power consumption cordless telephone.Fifthly,the expander has a 6-dB amplifier to allow received signal amplification.The last one is SOP package with 1.27 or 0.8 mm pitch pins.

What comes next is about the absolute maximum ratings (Ta=25).The V_CC (supply voltage) is 7.5 V.The P_D (power dissipation) is 280 mW.The T_opr (operating ambient temperature) is from -20 to +75.The T_stg (storage temperature) is from -55 to +125.Then is about the recommended operating range.The V_CC (operating supply voltage) is from 2 to 5 V.

The following is about the electrical characteristics (Ta=25).The minimum I_CC (supply current) is 1.5 mA and the maximum is 6 mA at V_CC=3 V, no signal.The maximum I_CS (standby pin (H)) is 10 A.The minimum C1 (gain (1)) is -11 dB,the typical is -10 dB and the maximum is -9 dB at V_IN=V_IRC-20 dB,C1=V_ORC-V_OC1.The minimum C2 (gain (2)) is -22 dB,the typical is -20 dB and the maximum is -19 dB at V_IN=V_IRC-40 dB,C2=V_ORC-V_OC2.The minimum E1 (gain (1)) is -21 dB,the typical is -20 dB and the maximum is -19 dB at V_IN=V_IRE-10 dB,E1=V_ORE-V_OE1.The minimum E2 (gain (2)) is -41.5 dB,the typical is -40 dB and the maximum is -38.5 dB at V_IN=V_IRE-20 dB,E2=V_ORE-V_OE2.
