10V to 70V single supply — fits non-standard rails
The MAX14757EUE+ is a 4-channel SPST-NO analog switch that runs on either a single 10V to 70V supply or dual ±10V to 35V rails — wide enough for industrial signal conditioning, ATE pin electronics, or bench equipment where the supply isn't a standard 5V or 12V. On-resistance is 10 Ohm max, with channel-to-channel matching within 300 mOhm — the matching figure matters more than the absolute Ron when you're switching gain-setting resistors in a programmable amplifier.
Crosstalk and bandwidth — the signal-path limits
Crosstalk is -96 dB at 10 MHz, which keeps a 1 MHz sine on channel 1 from leaking into channel 2 at better than 16-bit resolution — fine for multiplexing ADC inputs or audio routing. The -3 dB bandwidth is 145 MHz, so the switch passes a 10 MHz clock with less than 0.5 dB of loss, but the 35 pF off-channel capacitance starts rolling off above 50 MHz — not a GHz part.
580 pC charge injection — watch the sample-and-hold
Charge injection is 580 pC typical — that is enough to shift a 10 nF hold capacitor by 58 mV when the switch opens. If you're using this ahead of a SAR ADC, the acquisition window needs to settle that glitch before the conversion starts. Turn-on time is 60 µs, turn-off is 3 µs — the asymmetry means the switch opens fast but closes slowly. In a multiplexer scanning channels at 10 kHz, the 60 µs on-time eats 60% of the period, so the downstream circuit has only 40 µs to settle.
16-TSSOP — field-swappable with steady hands
The 2.5 nA max off-leakage means it won't drift the signal when the channel is deselected.
Active production — no LTB pressure
The part ships in tubes, which means it arrives in a single strip of 16-TSSOP packages — fine for hand assembly or low-volume pick-and-place. No reel or tape-and-reel option is listed on this variant.
