DESCRIPTION

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.
