Channel-to-channel crosstalk measures -78 dB at 1 MHz, meaning a 1 Vpp signal on one channel couples less than 0.13 mV into an adjacent off-channel — sufficient for 12-bit precision analog paths at audio frequencies. Charge injection is specified at 0.5 pC typical, which translates to roughly 0.5 mV of glitch into a 1 nF sample-and-hold capacitor — a figure that matters when the multiplexer feeds a precision ADC or DAC reference input. ## Supply flexibility and switching performance Operates from a single supply rail of 2 V to 12 V or dual supplies of ±2 V to ±6 V, covering the common analog voltage domains from 3.3 V single-supply systems up to ±5 V bipolar instrumentation rails. Switching times are 200 ns turn-on and 100 ns turn-off maximum, allowing channel updates at rates up to roughly 3 MHz without signal degradation — adequate for audio switching, data acquisition front-ends, and test equipment signal routing. Off-leakage current is 1 nA maximum at 25°C, preserving DC accuracy in high-impedance sensor interfaces where a 10 MΩ source impedance would see only 10 mV of offset from leakage alone. Channel-to-channel on-resistance matching is within 1 Ohm, which simplifies gain calibration in multiplexed applications — the gain error from Ron variation across channels stays below 1.25% in a unity-gain buffer configuration. ## Package, temperature grade, and compliance ROHS3 Compliant per the manufacturer's declaration, with no restricted substances under exemption — no compliance expiry risk for products shipping into EU or California markets.","metaTitle":"MAX4581ESE+ Analog Devices 8:1 Mux, 80 Ohm, 16-SOIC","metaDescription":"MAX4581ESE+ 8:1 analog multiplexer from Analog Devices. 80 Ohm on-resistance, -78dB crosstalk at 1MHz, 0.5pC charge injection.
