GENERAL DESCRIPTION
The ADG804 is a low voltage 4-channel CMOS multiplexer
comprising four single channels. This device offers ultralow
on resistance of less than 0.8 Ω over the full temperature range.
The digital inputs can handle 1.8 V logic with a 2.7 V to 3.6 V
supply.
The ADG804 switches one of four inputs to a common output,
D, as determined by the 3-bit binary address lines, A0, A1, and
EN. A Logic 0 on the EN pin disables the device. The ADG804
has break-before-make switching.
The ADG804 is fully specified for 3.3 V, 2.5 V, and 1.8 V supply
operation. It is available in a 10-lead MSOP package.
