| NTE1641 Integrated Circuit 1024 Stage BBD for Audio Signal Delays Description: The NTE1641 is a 1024-stage long delay low noise BBD that provides a signal delay of up to 51.2msec. This device is suitable for use as the reverberation effect of an electronic musical instrument, or in stereo equipment, due to its long delay times. Features: D Variable delay time of audio signal: 5.12ms to 51.2ms. D Clock component cancellation capability. D No insertion loss: Li = 0dB typ. D Wide dynamic range: S/N 80dB typ. D Wide frequency response: fi 12kHZ. D Low distortion: THD = 0.5% typ. (Vi = 0.78Vrms) D Clock frequency range: 10 to 100kHZ. D P channel silicon gate process. D 8-Lead DIP plastic package. Applications: D Reverberation effect echo for P.A. and stereo equipment. D Chorus effect in electronic musical instruments. D Variable or fixed delay of analog signals D Telephone time compression and delay line for voice communication systems, etc. Absolute Maximum Ratings: (TA = +25C unless otherwise specified) Pin Voltage, VDD, VGG, VCP, VI . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -18V to +0.3V Output Voltage, VO . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -18V to +0.3V Operating Ambient Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -20 to +60C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -55 to +125C Operating Conditions: (TA = +25C unless otherwise specified) Parameter Drain Supply Voltage Gate Supply Voltage Clock Voltage "H" Level Clock Voltage "L" Level Clock Frequency Clock Pulse Width Clock Rise Time Clock Fall Time Clock Input Capacitance Clock Cross Point Input DC Bias Voltage Symbol VDD VGG VCPH VCPL fCP tW(CP)2 tr(CP)2 tf(CP)2 CCP VX2 VBias - - - 0 -5 - - - - - Condition Min -14 - 0 - 10 Typ -15 VDD+1 - VDD - Max -16 - -1 - 100 0.5T1 500 500 700 -3 -10 Unit V V V V kHZ - s ns V V V Electrical Characteristics: (TA = +25C, VDD = VCPL = -15V, VCPH = 0V, VGG = -14V, RL = 100k) Parameter Signal Delay Time Input Singal Frequency Input Voltage Amplitude Insertion Loss Total Harmonic Distortion Output Noise Voltage Signal to noise ratio Symbol tD fi i Li THD Vno S/N fCP = 40kHz, Vi = 1.5Vrms, 3dB down (0dB at fi = 1kHZ) fCP = 40kHZ, fi = 1kHZ, THD = 2.5% fCP = 40kHZ, fi = 1kHZ, Vi = 1.5Vrms fCP = 40kHZ, fi = 1kHZ, Vi = 0.78Vrms fCP = 100kHZ, Weighted by "A" curve Condition Min 5.12 12 1.5 -4 - - - Typ - - - 0 0.5 - 80 Max 51.2 - - 4 2.5 0.3 - Unit ms kHZ Vrms dB % mVrms dB Note 1.
