Abstract

PURPOSE:To increase the response speed very fast with small size, by commonly connecting output terminal of a plurality of bidirectional analog switches and applying a control signal to either one control terminal of the control terminals of the switches. CONSTITUTION:Resistors R1, R2-RN are connected in series between input terminals a0, a0', the terminal a0 is connected to an input terminal a1 of a bidirectional analog switch S1, the connecting point of the resistors R1, R2 is connected to the input terminal a2 of the bidirectional analog switch S2 similarly, and the terminal a0' is connected to an input terminal aN+1 of a bidirectional analog switch SN+1. Output terminals of the switches S1-SN+1 are commonly connected and a control signal is applied to one terminal of the control terminals of the N+1 sets of the switches S1-SN+1. Thus, this electronic controlled step volume is smaller in size that step volumes using relays and the response speed can be made very fast.
