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
