The MAX4511/MAX4512/MAX4513 are quad, single- pole/single-throw (SPST), fault-protected analog switch- es.
The MAX4511, MAX4512, and MAX4513 are quad, single‑pole/single‑throw (SPST) analog switches with fault‑protected inputs and rail‑to‑rail signal handling. They are pin‑compatible with DG201/DG202/DG213 and offer both normally‑open and normally‑closed configurations. The devices operate from dual supplies (±4.5 V to ±18 V) or a single supply (+9 V to +36 V) and accept TTL‑ and CMOS‑compatible logic levels.
Key features include on‑resistance up to 175 Ω (matched to 10 Ω between switches), off‑leakage as low as 0.5 nA at +25 °C, fault protection up to ±36 V (±40 V with power off), and the ability of the COM pin to source or sink up to 10 mA during a fault. Detailed electrical characteristics, pin configurations, and typical operating curves are provided for both dual‑ and single‑supply operation.
| On‑Resistance (max) | 175 Ω |
|---|---|
| On‑Resistance match between switches (max) | 10 Ω |
| Off‑Leakage Current (typical at +25 °C) | 0.5 nA |
| Supply Voltage Range – Dual | ±4.5 V to ±18 V |
| Supply Voltage Range – Single | +9 V to +36 V |
| Logic Input Thresholds | 0.8 V (low) / 2.4 V (high) |
| Continuous Current per Terminal | ±30 mA |
The COM pin can source or sink about ±10 mA from the supply rails in a fault condition.
Logic inputs recognize a low level at 0.8 V and a high level at 2.4 V.
The off‑leakage current is typically 0.5 nA at +25 °C.
