The MAX4651/MAX4652/MAX4653 quad analog switches feature 4Ω max on-resistance (RON) when operating from a single +5V supply. RON is matched between switches to 0.2Ω (max) and is flat (0.8Ω max) over the specified signal range. Each switch can handle Rail-to-Rail® analog signals. Off-leakage current is 0.1nA at +25°C. These switches are ideal in low-distortion applications and are the preferred solution over mechanical relays in automated test equipment or applications where current switching is required. They have low power requirements, require less board space, and are more reliable than mechanical relays. The MAX4651/MAX4652/MAX4653 operate from a single +1.8V to +5.5V supply, making them ideal for use in battery-powered applications. The MAX4651 has four normally closed (NC) switches, the MAX4652 has four normally open (NO) switches, and the MAX4653 has two NO and two NC switches.
The MAX4651, MAX4652 and MAX4653 are low‑on‑resistance, low‑voltage quad SPST CMOS analog switches that operate from a single +1.8 V to +5.5 V supply. They handle rail‑to‑rail analog signals, offer low off‑leakage (0.1 nA at +25 °C) and are suited for battery‑powered, audio/video routing, data‑acquisition and relay‑replacement applications.
The devices are available in 16‑pin QFN, TSSOP and SO packages, as well as a 20‑pin QFN package. Electrical characteristics include 4 Ω max on‑resistance at 5 V, turn‑on time ~14 ns, turn‑off time ~12 ns, and an operating temperature range of –40 °C to +85 °C. Detailed pin descriptions, switching‑time graphs and package drawings are provided.
