It switches one common line among four independent channels, with a maximum on-resistance of 100 Ohms and channel-to-channel matching of 4 Ohms. The part operates from a single supply of 2 V to 15 V, or dual supplies of ±2.7 V to ±8 V, and is specified over the 0°C to 70°C commercial temperature range. Typical applications include audio signal routing, data acquisition systems, and test equipment where low charge injection (5 pC max) and low leakage (100 pA max) are required. ## 100 Ohm on-resistance and crosstalk The 100 Ohm maximum on-resistance sets the insertion loss and signal attenuation through the switch. The -92 dB crosstalk at 100 kHz means channel-to-channel bleed is well below the noise floor of a 16-bit ADC. ## Switching speed and charge injection Maximum turn-on and turn-off times are both 150 ns. Charge injection is 5 pC maximum. ## Package and supply flexibility The 14-SOIC (0.154\", 3.90 mm width) footprint is a common industry standard, compatible with existing PCB layouts for Maxim SP4T switches in this package. Single-supply operation down to 2 V allows battery-powered designs, while dual supplies up to ±8 V give headroom for ±5 V analog rails. The part is ROHS3 compliant.","metaTitle":"MAX4518CSD+ SP4T Analog Switch, 100Ohm, 14-SOIC","metaDescription":"MAX4518CSD+ SP4T analog multiplexer/demultiplexer, 100Ohm on-resistance, -92dB crosstalk at 100kHz, 14-SOIC surface mount.
