| NTE1634 Integrated Circuit Dual Preamp w/ALC Description: The NTE1634 is a monolithic integrated circuit in a 14-Lead DIP type package consisting of a dual equalizer amplifier with automatic level control (ALC) and is suitable for stereo radio cassette applications. Features: D Dual Equalizer Amplifier with Built-In ALC Circuit. D Recording Amp Available Because of High Gain Characteristic (Variable Monitor Possible). D Good Channel Separation (Sep = 50dB Typ) D Capable of Direct Meter Driving and ALS Transistor. D Good ALC Response Balance Between Channels. D Wider Operating Supply Voltage Range (4V to 13V) Absolute Maximum Ratings: (TA = +25C unles otherwise specified) Supply Voltage, VCC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 14V Power Dissipation, PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 600mW Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -20 to +70C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -40 to +125C ALC TR Maximum Current . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3.5mA Electrical Characteristic: (TA = +25C, VCC = 5V, RL = 10k: Playback, RL = 680: Recording unless otherwise specified) Parameter Circuit Current Voltage Gain (Open Loop) Voltage Gain (Closed Loop) Symbol ICC AVO AV1 AV2 Output Voltage Total Harmonic Distortion Input Resistance Equivalent Input Noise Voltage Cross Talk ALC Range ALC Balance ALC Distortion VO THD Ri VNI CT BW(-3dB)=20Hz to 20kHz Rg = 2.2K Vi = -60dBm, Record Vi = -20dBm, Record Vi = -20dBm, Record Play Record THD = 1%, Play VO = 0.5V, Play Test Conditions Vi = 0 Min - - - - 0.9 - 21 - 40 35 - - Typ 4.5 85 40 58 1.2 0.1 30 1.0 50 45 0 0.5 Max 10 - - - - 1.0 - 2.0 - - 2.0 2.0 Unit mA dB dB dB V % k V dB dB dB % Pin Connection Diagram GND 1 Output 1 2 PC 1 3 NF 1 4 Input 1 5 ALC Output 1 6 ALC Input 7 14 VCC 13 Output 2 12 PC 2 11 NF 2 10 Input 2 9 ALC Output 2 8 DC 14 8 1 7 .785 (19.95) Max .300 (7.62) .200 (5.08) Max .100 (2.45) .600 (15.24) .099 (2.5) Min |
