The 50 MHz -3 dB bandwidth supports video-rate signals and high-speed digitizers; the 18 ns turn-on and 7 ns turn-off times keep channel switching fast enough for 10 MSPS multiplexed ADC systems. Crosstalk is -85 dB at 1 MHz — a 50 mVpp signal on an adjacent channel leaks only about 2.8 µV into the active channel, well below the noise floor of a 16-bit ADC. ## Charge injection and leakage — the precision analog specs Charge injection is 13 pC typical — when the switch opens, that glitch charge dumps into the sampling capacitor. In a 100 pF hold cap it creates a 130 mV step, so this mux is better suited for continuous-time signals than for switched-capacitor sample-and-hold front ends without an external buffer. Maximum off-state leakage is 250 pA — at 25°C the typical value is lower, but budgeting the max across temperature keeps the error term under 0.01% of a 10 µA sensor current. Source-off capacitance is 9 pF, drain-off is 40 pF — the drain capacitance dominates the RC time constant at the output node, so keep the downstream load impedance below 50 kOhm to avoid bandwidth rolloff. ## Package, temperature grade, and compliance The supplier device package is 16-TSSOP. ROHS3 compliant — no restricted substances; fits EU and global environmental regulations without exemption paperwork.","metaTitle":"MAX4638EUE+T Analog Devices 8:1 Mux, 3.5Ohm, 16-TSSOP","metaDescription":"Active production 8:1 analog multiplexer from Analog Devices. 3.5 Ohm on-resistance, -85dB crosstalk at 1MHz, 50MHz bandwidth. 16-TSSOP package.

For a 1 Vpp audio signal on an adjacent channel, the bleed-through is roughly 56 µV — below the noise floor of a 16-bit ADC with a 3.3 V reference.
