Each of the four independent switches handles analog or digital signals with a maximum on-resistance of 3.5 kOhm and channel-to-channel matching of 175 Ohm. The switch operates from dual supplies of ±5V to ±18V or a single supply of 10V to 30V, making it flexible for split-rail or single-rail analog front-ends. Typical applications include audio and video signal routing, data acquisition systems, and test equipment where low crosstalk (-90 dB at 100 kHz) and low charge injection (2 pC) preserve signal integrity. ## Key ratings and what they mean for the BOM The 3.5 kOhm on-resistance is relatively high compared to modern analog switches — expect a voltage drop of several millivolts at typical signal currents. This part suits high-impedance signal paths where the switch resistance does not load the source. The 1 µs turn-on and 500 ns turn-off times are adequate for audio switching and low-speed multiplexing but not for high-speed data or video line rates above a few megahertz. The 2 pC charge injection is low enough for sample-and-hold and DAC deglitching without external compensation. The -90 dB crosstalk at 100 kHz means adjacent channels stay isolated by better than 90 dB — important for precision multichannel measurements. ## Temperature grade and deployment environment Rated for the commercial temperature range of 0°C to 70°C, this part is intended for indoor, controlled-environment equipment such as benchtop instruments, audio gear, and office electronics. It is not specified for industrial or automotive environments where extended temperature or AEC-Q100 qualification is required. The 16-SOIC package (3.90 mm width) is a common footprint for analog switches and multiplexers, compatible with standard SOIC-16 land patterns. ## Crosstalk and isolation performance The -90 dB crosstalk at 100 kHz keeps adjacent channels isolated by better than 90 dB.","metaTitle":"MAX327CSE+T Analog Switch IC, SPST-NO, 3.5 kOhm, 16-SOIC","metaDescription":"MAX327CSE+T quad SPST-NO analog switch, 3.5 kOhm on-resistance, ±5V to ±18V dual supply, -90 dB crosstalk.
