DESCRIPTION

The DG9451, and DG9453 are high precision single and

dual supply CMOS analog multiplexers. DG9451 is an

8-channel multiplexer, and the DG9453 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 DG9451, and

DG9453 are fully specified at + 12 V, + 5 V and ± 5 V. All

control logic inputs have guaranteed 1.4 V high limit when

operating from + 5 V or ± 5 V supplies and 1.65 V when

operating from a + 12 V supply.

The DG9451, and DG9453 are precision multiplexers of low

leakage, low charge injection, and low parasitic capacitance.

They conduct equally well in both directions, offer rail to rail

analog signal handling and can be used both as multiplexers

as well as de-multiplexers.

The DG9451, and DG9453 operating temperature is

specified from - 40 °C to + 85 °C and are available in 16 pin

TSSOP and the ultra compact 1.8 mm x 2.6 mm miniQFN16

packages.
