Crosstalk is -85 dB at 1 MHz, so a 3 Vpp signal on an adjacent channel bleeds less than 170 µV into the active path — relevant for 12-bit+ systems where LSB noise budgets are tight. Charge injection is 13 pC typical, which translates to a voltage glitch on the sampling capacitor; the 9 pF source-off / 40 pF drain-off capacitance helps settle that glitch before the ADC conversion starts. The -3 dB bandwidth is 50 MHz, so the mux passes signals well above the audio band and into low-end video without roll-off. ## Package and board integration Supplied in Tube format — one tube typically holds 75 units; for reel quantities check the alternate ordering suffix.","metaTitle":"MAX4638ETE+ Analog Devices 8:1 MUX, 3.5Ω, 16-TQFN","metaDescription":"MAX4638ETE+ 8:1 analog multiplexer from Analog Devices. 3.5Ω max on-resistance, 1.8V–5.5V supply, 50 MHz bandwidth.
