ADG804

Data Sheet FEATURES 0.5 Ω typical on resistance 0.8 Ω maximum on resistance at 125°C 1.65 V to 3.6 V operation Automotive temperature range: –40°C to +125°C High current carrying capability: 300 mA continuous Rail-to-rail switching operation Fast switching times <25 ns Typical power consumption (<0.1 µW) APPLICATIONS MP3 players Power routing Battery-powered systems PCMCIA cards Cellular phones Modems Audio and video signal routing Communication systems 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. 0.5 Ω CMOS 1.65 V TO 3.6 V 4-Channel Multiplexer ADG804 FUNCTIONAL BLOCK DIAGRAM ADG804 S1 2 S2 9 S3 4 8D S4 7 04307-0-001 1 OF 4 DECODER 1 10 5 A0 A1 EN Figure 1.
