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.

PRODUCT HIGHLIGHTS

1. <0.8 Ω over full temperature range of –40°C to +125°C.

2. Single 1.65 V to 3.6 V operation.

3. Operational with 1.8 V CMOS logic.

4. High current handling capability (300 mA continuous

current at 3.3 V).

5. Low THD + N (0.02% typ).

6. Small 10-lead MSOP package.

D

04307-0-001

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.
