MAX4910/MAX4911/MAX4912 quad, single-pole/double-throw (SPDT), clickless audio switches fea- ture negative signal capability that allows signals as low as VCC-5.5V to pass through without distortion
The MAX4910, MAX4911, and MAX4912 are quad single‑pole/double‑throw (SPDT) analog switches that operate from a +1.8 V to +5.5 V single supply and feature click‑less operation with built‑in shunt resistors to suppress pop‑and‑click sounds. They support negative‑signal handling, allowing signals as low as VCC‑5.5 V to pass without distortion, and include a break‑before‑make feature for clean switching.
The devices are offered in a 16‑pin TQFN‑EP (3 mm × 3 mm) package and are rated for –40 °C to +85 °C operation. The datasheet provides absolute maximum ratings, detailed electrical characteristics (on‑resistance, leakage, PSRR, crosstalk, THD, etc.), pin‑out tables, typical application circuits, and package dimensions.

They operate from a single supply of +1.8 V to +5.5 V.
The switches have negative‑signal capability that lets signals as low as VCC‑5.5 V pass without distortion.
Typical on‑resistance for channels 1 and 3 is 0.37 Ω.
No, the MAX4912 lacks shunt resistors on NC2 and NC4 terminals.
