Each switch presents a maximum on-resistance of 4 Ohm, with channel-to-channel matching of 200 mOhm, making it suitable for precision analog signal routing where consistent attenuation across channels is required. Switching times are 275 ns (turn-on) and 175 ns (turn-off) maximum, which supports multiplexing in data-acquisition systems and audio signal routing where fast settling is needed. ## Signal integrity specs: crosstalk, charge injection, leakage Crosstalk is specified at -60 dB at 1 MHz, which means that a signal on one channel couples into an adjacent channel at a level 60 dB below the signal — adequate for 10-bit to 12-bit accuracy in multiplexed systems where channel isolation matters. Charge injection is 300 pC typical, a parameter that affects the hold step in sample-and-hold circuits; the injected charge causes a voltage error proportional to the load capacitance. Off-leakage current is 500 pA maximum, and channel capacitance (CS(off), CD(off)) is 34 pF each. Low leakage preserves the accuracy of high-impedance sensor interfaces, while the capacitance contributes to settling time in switched-capacitor circuits.","metaTitle":"MAX4666ESE+ Analog Devices SPST Switch, 4Ohm, 16-SOIC","metaDescription":"MAX4666ESE+ Analog Devices quad SPST switch, 4Ohm on-resistance, 275ns switching, -40 to 85°C.
