8-Channel, Dual 4-Channel, Triple 2-Channel Multiplexers

DESCRIPTION

The DG9251, DG9252, and DG9253 are high precision

single and dual supply CMOS analog multiplexers. DG9251

is an 8-channel multiplexer, the DG9252 is a dual 4-channel

multiplexer, and the DG9253 is a triple 2-channel multiplexer

or triple SPDT.

Designed to operate from a + 2.7 V to + 16 V single supply

or from a ± 2.7 V to ± 5 V dual supplies, the DG9251,

DG9252, and DG9253 are fully specified at + 16 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 + 16 V supply.

The

DG9251,

DG9252,

and

DG9253

are

precision

multiplexers of low leakage, low charge injection, and

lowparasitic capacitance. They conduct equally well in

bothdirections, offer rail to rail analog signal handling and

can

beused

both

as

multiplexers

as

well

as

de-multiplexers.The

DG9251,

DG9252,

and

DG9253

operating temperature is specified from - 40 °C to + 85 °C

and are available in ultra compact 1.8 mm x 2.6 mm

miniQFN16 packages.
