Switching is fast — 18 ns turn-on and 7 ns turn-off max — so the part can handle time-division multiplexing at rates that would choke a slower analog switch. The 100 mOhm channel-to-channel matching (ΔRon) preserves differential signal balance in precision measurement chains. ## Supply flexibility and signal isolation Charge injection is 13 pC typical — low enough that sample-and-hold droop stays manageable at moderate acquisition rates. Off-isolation is dominated by the -85 dB crosstalk at 1 MHz, meaning adjacent channel bleed is well below the noise floor of most 12-bit ADC front-ends. The off-channel capacitance (9 pF source, 20 pF drain) loads the bus lightly, preserving signal rise times in multiplexed arrays. ## Industrial temperature range and 16-SOIC footprint Surface-mount assembly with a standard reflow profile is straightforward; no special baking or handling beyond MSL precautions. No official cross-reference or second-source is recorded; the part is the primary BOM entry for this switch function.","metaTitle":"MAX4639ESE+T Analog Devices SP4T Switch, 3.5 Ohm, 16-SOIC","metaDescription":"MAX4639ESE+T dual SP4T analog switch, 3.5 Ohm on-resistance, 85 MHz bandwidth, -85 dB crosstalk at 1 MHz.
