AD532 Multiplier IC and Its Pin Configurations

The AD532 is the first pre-trimmed single chip monolithic multiplier/divider. This device guarantees a maximum multiplying error of +- 1% and a +-10 V output voltage without the need for any output op amp or external trimming resistors. It’s simplicity of use provides design engineers with an attractive alternative to modular multipliers because the AD532 is internally trimmed. The AD532 […]

Direct Coupled Discrete Astable Multivibrator

This flip-flop circuit  is a free running/astable multivibrator one,  with bases and collector of both emitter biased transistor are directly coupled to each other.  Switching action is supported by means of capacitor in each emitter circuit.  This configuration produce a triangle waves at emitters. Since neither transistor can remain permanently cut off, then a free running oscillation will be generated. […]
