MAX4604

The MAX4604/MAX4605/MAX4606 quad analog switches feature 5Ω max on-resistance. On-resistance is matched between switches to 0.5Ω max and is flat (0.5Ω max) over the specified signal range. Each switch can handle rail-to-rail analog signals. The off-leakage current is only 2.5nA max at +85°C. These analog switches are ideal in low-distortion applications and are the preferred solution over mechanical relays in automatic test equipment or in applications where current switching is required. These switches have low power requirements, require less board space, and are more reliable than mechanical relays.

The MAX4604 has four normally closed (NC) switches, the MAX4605 has four normally open (NO) switches, and the MAX4606 has two NC and two NO switches.

These switches operate from a single supply of +4.5V to +36V or from dual supplies of ±4.5V to ±20V. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL/CMOS logic compatibility when using ±15V supplies or a single +12V supply.
