DG451 Overview
The DG451 series has four independently selectable high voltage (44 V) SPST switches, each with a typical on resistance of 4 Ω and a typical flatness of 0.2 Ω, ideal parameters for low distortion audio signal switching. The DG451 (NC) and DG452 (NO) are identical except for the digital logic control input, which is inverted as shown in the Truth Table. The DG453 has two normally closed and two normally open switches.
