ADG333ABRSZ-REEL

模拟开关 IC QUAD SPDT SWITCH I.C.

GENERAL DESCRIPTION

The ADG333A is a monolithic CMOS device comprising four independently selectable SPDT switches. It is designed on an LC2MOS process, which provides low power dissipation yet achieves a high switching speed and a low on resistance.

The on resistance profile is very flat over the full analog input range, ensuring good linearity and low distortion when switching audio signals. High switching speed also makes the part suitable for video signal switching. CMOS construction ensures ultralow power dissipation, making the part ideally suited for portable, battery-powered instruments.

PRODUCT HIGHLIGHTS

1\. Extended signal range.

   The ADG333A is fabricated on an enhanced LC2MOS

   process, giving an increased signal range which extends to

   the supply rails.

2\. Low power dissipation.

3\. Low RON.

4\. Single-supply operation.

   For applications where the analog signal is unipolar, the

   ADG333A can be operated from a single rail power supply.

   The part is fully specified with a single 12 V supply.
