Each switch connects one of four inputs to a common output, with a 100 Ohm max on-resistance and 1.5 Ohm channel-to-channel matching. That matching figure matters when you're scanning multiple sensor channels into a single ADC: the gain error from Ron variation stays under 1.5 Ohm between channels, so you don't lose a bit of resolution to the mux itself. Turn-on and turn-off are both 150 ns. Crosstalk is -92 dB at 100 kHz. ## Supply range and temperature — where it lives on the board The part runs on a single supply from 5 V to 30 V, or dual supplies from ±5 V to ±20 V. That dual-supply capability lets it handle bipolar analog signals without external level shifting — common in audio or industrial signal chains where the signal swings below ground. The -40°C to 85°C temperature range covers industrial and outdoor telecom enclosures; the through-hole 16-DIP package is a repair-bench favourite because it's socketable and easy to swap when the scorch mark tells you which part actually died. ## Leakage and charge injection — the quiet details Off-channel leakage is rated at 750 pA max, and charge injection is 2 pC. For a precision analog front end, these specs tell you how much the mux corrupts the signal when it switches. 2 pC of charge injection will cause a small glitch on the output — fine for most DC measurements, but worth noting if you're multiplexing a high-impedance sensor and the settling time matters. The off-capacitance (3 pF source, 26 pF drain) also contributes to settling, especially at higher scan rates. ## Lifecycle and sourcing The MAX309EPE+ carries an Active lifecycle status and is ROHS3 compliant.","metaTitle":"MAX309EPE+ Dual SP4T Analog Multiplexer, 100 Ohm, 16-DIP","metaDescription":"MAX309EPE+ dual 4:1 analog multiplexer with 100 Ohm max on-resistance, 150 ns switching, -92 dB crosstalk.
