Each of the four SPST-NO switches presents a maximum 1.6 Ω on-resistance, with channel-to-channel matching held to 200 mΩ — this keeps the insertion loss uniform across all four paths in a multiplexed signal chain. ## Signal integrity: bandwidth and crosstalk floor With a -3 dB bandwidth of 66 MHz and crosstalk rated at -84 dB at 1 MHz, the MAX4678EUE+T handles analog signals up to video frequencies without coupling between adjacent channels. The 350 ns turn-on and 150 ns turn-off times support switching rates that keep up with most audio, data acquisition, and instrumentation multiplexing requirements. ## Supply rail flexibility and charge injection Charge injection is 85 pC — a figure to budget in sample-and-hold or precision DAC output stages where the injected charge settles into the hold capacitor. ## Leakage and capacitance for high-impedance inputs Maximum off-leakage current is 1 nA, and the channel capacitance is 85 pF per pole — both specifications that preserve signal accuracy when the switch is in the high-impedance state, such as in a multi-channel data logger or a precision voltage reference scanner.","metaTitle":"MAX4678EUE+T Analog Devices SPST Switch, 1.6Ω, 16-TSSOP","metaDescription":"MAX4678EUE+T quad SPST-NO analog switch, 1.6Ω on-resistance, -84dB crosstalk at 1MHz, 66MHz bandwidth.
