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. Pin Assignment GND CP1 IN VGG DIP 8 PIN GND CP 2 BL3208B OUT 1 OUT 2 DIP 8 PIN CP 1 VDD VGG IN BL3208A OUT 2 OUT 1 CP 2 VDD
