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: 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.
