BL3208A/B 2048-Stage BBD

Description

The BL3208A/B is a 2048-stage low voltage operation, and low noise BBD variable delay line in audio

frequency range. The device operates on +5V to +10V supply and provides a signal delay up to 102.4ms.The

BL3208 contains 3208A and 3208B two classes. The only differences between them are the outlook and pin

assignment.
