The DG4051A, DG4052A and DG4053A are high precision CMOS analog multiplexers. The DG4051A is an 8-channel multiplexer, the DG4052A is a dual 4-channel multiplexer and the DG4053A is a triple 2-channel multiplexer or triple SPDT. Designed to operate from a + 2.7 V to + 12 V single supply or from a ± 2.5 V to ± 5 V dual supplies, the DG4051A, DG4052A and DG4053A are fully specified at + 3 V, + 5 V and ± 5 V. All control logic inputs have guaranteed 2.0 V logic high limit when operating from + 5 V or ± 5 V supplies and 1.4 V when operating from a + 3 V supply. Channel leakage is typically in the range of 10 pA, and switch charge injection is less than 0.5 pC. Coupled with very low switch capacitance, these devices are ideal for high precision signal switching and multiplexing. All switches conduct equally well in both directions, offering rail to rail analog signal switching and can be used both as multiplexers as well as de-multiplexers. The DG4051A, DG4052A and DG4053A operating temperature is specified from – 40 °C to + 125 °C and are available in 16 pin TSSOP and the ultra compact 1.8 mm x 2.6 mm miniQFN16 packages.
