Each of the two independent circuits selects one of four inputs to a common output, implementing a 4:1 mux function. The part is specified for dual-supply operation from ±4.5 V to ±18 V, making it suitable for routing bipolar analog signals in test equipment, data acquisition systems, and audio switching applications within controlled-temperature environments. ## 1.8 kOhm on-resistance — what it means for signal integrity The maximum on-state resistance of 1.8 kOhm is high by modern standards. In a voltage-divider configuration with a typical 10 kOhm load, the mux adds roughly 15% attenuation. For precision analog measurements, the load impedance should be at least 100 kOhm to keep the insertion loss below 2%. The resistance also varies with supply voltage and signal level — the datasheet curve should be consulted for the operating point. This part is not suited for low-impedance or high-current paths. ## Dual-supply requirement and single-supply compatibility The MAX359CWE+ is specified for dual supplies only — ±4.5 V to ±18 V. If a single supply is the only option, look for a different mux family. The dual-rail requirement means the analog signal swing can go negative relative to ground, which is useful for bipolar signals in ATE or audio crosspoint matrices. The commercial temperature range (0°C to 75°C) limits deployment to lab, office, or indoor equipment — not industrial or automotive. ## Switching speed and leakage Typical turn-on and turn-off times are 300 ns each. This is adequate for audio-frequency multiplexing, relay-replacement, and low-speed data acquisition (sample rates below 1 MHz). ## Package and mounting The 16-SOIC wide-body package (0.295-inch body width, 7.50 mm) is a surface-mount footprint common for analog muxes. The supplier device package is also 16-SOIC. ## Lifecycle and sourcing The MAX359CWE+ is listed as Active with ROHS3 compliance. The part is available through independent distribution and is sourced to order against an RFQ.","metaTitle":"MAX359CWE+ Analog Multiplexer, SP4T x2, 1.8kOhm, 16-SOIC","metaDescription":"MAX359CWE+ dual SP4T analog multiplexer, 1.8kOhm max on-resistance, ±4.5V to ±18V dual supply, 16-SOIC.
