| DUAL LOW NOISE EQ AMP S1A0211X01 INTRODUCTION The S1A0211X01 is a monolithic integrated circuit consisting of a 2-channel pre-amplifier in an 8-pin plastic single in-line package. 8-SlP FEATURES * * * * Recommended operating supply voltage range: VCC = 5V to 14V Low noise (VNI = 1.0V: Typ) High channel separation Minimum number of external parts required ORDERING INFORMATION Device S1A0211X01-I0U0 package 8-SlP Operating Temperature -20C -- +70C BLOCK DIAGRAM + AMP1 + AMP2 1 INPUT1 2 3 4 VCC 5 6 7 8 INPUT2 NF1 OUTPUT1 GND OUTPUT2 NF2 1 S1A0211X01 DUAL LOW NOISE EQ AMP ABSOLUTE MAXIMUM RATINGS (Ta = 25C) Characteristic Supply Voltage Power Dissipation Operating Temperature Storage Temperature Symbol VCC PD TOPR TSTG Value 18 200 - 20 - + 70 - 40 - + 125 Unit V mW C C ELECTRICAL CHARACTERISTICS (Ta=25C, VCC = 9V, RL= 10k, RG = 600, f = 1kHz, NAB, unless otherwise specified) Characteristic Quiescent Circuit Current Open Loop Voltage Gain Closed Loop Voltage Gain Output Voltage Total Harmonic Distortion Input Resistance Equivalent Input Noise Voltage Cross Talk Symbol ICCQ GVO GVC VO THD RI VNI CT R G = 2.2k BW (- 3dB) = 15Hz - 30kHz R G = 2.2k VO = 0.5V THD = 1% VO = 0.5V - VI = 0 - Test Conditions Min. - 65 30 1.1 - 70 - 50 Typ. 4.0 80 35 1.3 0.1 100 1.0 65 Max. 6.0 - 37 - 0.3 - 2.0 - Unit mA dB dB V % k V dB 2 DUAL LOW NOISE EQ AMP S1A0211X01 TEST CIRCUIT Icc VCC + 47F 100 47F 0.033F + 4 2 10F + 2.7K 100K 10F + 3 1 INPUT1 OUTPUT1 10K S1A0211X01 10F + 8 6 7 5 + 10F + INPUT2 0.033F 2.7K 47F 100 100K OUTPUT2 10K 3 S1A0211X01 DUAL LOW NOISE EQ AMP APPLICATION INFORMATION External Components C2 (C9): Input coupling capacitor These components are concerned with the output noise and operation starting time. Its capacitance is adequate for 10F. As C2 (C9) below 4.7F extends the operation starting time, a capacitance of over 4.8F is recommended. C3 (C8): Negative feedback capacitor These components decide the low cut-off frequency, which is determined as follows: 1 C3 (C8) = 2f * R (R ) L 2 7 where, fL: low cut-off frequency. A large C3 (C8) makes the operation starting time of an amplifier late. Its capacitance is adequate for 47 F. C4, R3, R2 (C7, R4, R5): Equalizer network These components decide the frequency response of an equalizer amplifier. The time constant of standard NAB characteristic is as follows: Tape Speed Time Constant C4 (R2 + R3) C4, R2 9.5 cm/sec 3,180 sec 90 sec 4.75 cm/sec 1,590 sec 120 sec C11 Filter capacitor of the power line This should be located as close to the supply voltage pin (Pin 4) as possible. The recommended value is 47F. C1 (C10): Protection capacitor These components protect against wave damage of strong electric fields. They also protect against engine noise damage and block oscillation during high amplifying operations. C5 (C6): Output coupling capacitor The recommended value is 10F. 4 DUAL LOW NOISE EQ AMP S1A0211X01 APPLICATION CIRCUIT 1k + VCC R1 C3 C11 100 C4 47F 0.033F R2 R3 2.7K 100K 47F + 4 C2 10F CH1 INPUT1 C1 + 2 1 10F 3 + C5 CH1 OUTPUT1 10K 1000P C9 10F + S1A0211X01 8 6 7 5 + 10F + CH2 INPUT2 C10 1000P R5 0.033F C7 2.7K R7 47F 100 100K C6 10K CH2 OUTPUT2 C8 C6 5 S1A0211X01 DUAL LOW NOISE EQ AMP NOTES 6 |
