The MAX4675/MAX4676 single analog switches have 3Ω (max) on-resistance (RON) and 0.7Ω flatness when operating from dual ±5V supplies. These switches can handle Rail-to-Rail® analog signals. Off-leakage current is 0.1nA at TA = +25°C. The MAX4675/MAX4676 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 are more reliable than mechanical relays, have low power requirements (<1µA), and are available in a space-saving 6-pin SOT23 package. The MAX4675 has a single normally open (NO) switch, and the MAX4676 has a single normally closed (NC) switch. The MAX4675/MAX4676 operate from either a single +2.7V to +5.5V or dual ±2.7V to ±5.5V supplies, making them ideal for use in digital card applications and single-ended 75Ω systems.
The MAX4675 and MAX4676 are single SPST analog switches offered in a 6‑pin SOT‑23 package. They feature low on‑resistance, rail‑to‑rail signal handling, and very low off‑leakage, making them suitable for test equipment, communication systems, audio routing, and other low‑distortion applications.
The document includes absolute maximum ratings, detailed electrical characteristics for both dual‑supply and single‑supply operation, typical performance curves, pin descriptions, and recommended application guidelines such as over‑voltage protection and power‑supply sequencing.
