ADG444BR

The ADG441, ADG442, and ADG444 are monolithic CMOS
devices that comprise of four independently selectable switches.
They are designed on an enhanced LC2
MOS process that
provides low power dissipation yet gives high switching speed
and low on resistance.
The on resistance profile is very flat over the full analog input
range, which ensures good linearity and low distortion when
switching audio signals. High switching speed also makes the
parts suitable for video signal switching. CMOS construction
ensures ultralow power dissipation, making the parts ideally
suited for portable and battery-powered instruments. The
ADG441, ADG442, and ADG444 contain four independent
SPST switches. Each switch of the ADG441 and ADG444 turns
on when a logic low is applied to the appropriate control input.
The ADG442 switches are turned on with logic high on the
appropriate control input. The ADG441 and ADG444 switches
differ in that the ADG444 requires a 5 V logic power supply
that is applied to the VL pin. The ADG441 and ADG442 do not
have a VL pin, the logic power supply is generated internally by
an on-chip voltage generator.
