Each switch channel carries a maximum on-resistance of 3.5 Ohm, with channel-to-channel matching held to 100 mOhm, so the insertion loss stays uniform across all four inputs. The -3 dB bandwidth of 85 MHz and crosstalk of -85 dB at 1 MHz mean it handles baseband analog signals — audio, low-frequency instrumentation, or control voltages — without bleeding between channels. ## Supply rails and logic compatibility Runs from a single supply between 1.8 V and 5.5 V, or dual supplies at ±2.5 V. The 1.8 V minimum single-supply floor makes it usable in 1.8 V logic systems, while the 5.5 V ceiling covers 3.3 V and 5 V rails. Switching times are fast — 18 ns turn-on, 7 ns turn-off — so it can be used for signal routing in multiplexed data-acquisition front ends without introducing timing skew. ## Charge injection and leakage — what they mean for precision Charge injection is rated at 13 pC, and off-state leakage is 250 pA maximum. For a high-impedance sample-and-hold or a precision ADC input, 13 pC of injected charge translates to a small voltage glitch on the hold capacitor — acceptable for 12-bit systems if the source impedance is kept low. The 250 pA leakage keeps the off-channel from loading the signal bus in multiplexed measurements. ## Package and temperature range Housed in a 16-TSSOP (4.40 mm width) with surface-mount termination. The operating temperature range is -40°C to 85°C, covering industrial and commercial environments — outdoor telecom cabinets, factory-floor data acquisition, or benchtop instrumentation. The part is ROHS3 compliant per the listing. ## Lifecycle and sourcing posture The Tape & Reel suffix (T) means it ships on 7-inch reels, standard for automated pick-and-place.","metaTitle":"MAX4639EUE+T Analog Devices SP4T Analog Switch, 3.5 Ohm","metaDescription":"MAX4639EUE+T dual SP4T analog switch with 3.5 Ohm on-resistance, -85 dB crosstalk at 1 MHz, 85 MHz bandwidth.
