MAX4607/MAX4608/MAX4609 are dual analog switches featuring 2.5Ω max low 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 equip- ment or applications where current switching is required. They have low power requirements, require less board space, and are more reliable than mechanical relays. The MAX4607 has two normally closed (NC) switches, the MAX4608 has two normally open (NO) switches, and the MAX4609 has one NC and one NO switch. 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 dual ±15V or a single +12V supply.
The MAX4607, MAX4608, and MAX4609 are dual analog switches with low on‑resistance (2.5 Ω max) and matched channels (0.5 Ω max). They handle rail‑to‑rail signals, offer low off‑leakage (2.5 nA max at +85 °C), and include ESD protection >2 kV.
The devices operate from a single supply of +4.5 V to +36 V or dual supplies of +4.5 V to +20 V, with TTL/CMOS‑compatible logic thresholds (+0.8 V low, +2.4 V high). The datasheet lists pin configurations, electrical characteristics, typical operating curves, and test circuit diagrams for design reference.
