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 instru-
ment, 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: L_i = 0dB typ.
D Wide dynamic range: S/N ≅ 80dB typ.
D Wide frequency response: f_i ≤ 12kH_Z.
D Low distortion: THD = 0.5% typ. (V_i = 0.78V_rms)
D Clock frequency range: 10 to 100kH_Z.
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.
