4 Ohm on-resistance and signal integrity
The MAX4644EUT+T is an SPDT analog switch with a maximum on-resistance of 4 Ohm, ensuring minimal signal attenuation in precision analog paths. The 100 mOhm channel-to-channel matching keeps gain errors consistent across the two channels — important for differential signal chains or multiplexed sensor inputs. Switching times of 15 ns (ton) and 5 ns (toff) let it handle fast multiplexing in data acquisition or audio routing without introducing timing skew. The -82 dB crosstalk at 1 MHz means adjacent channels stay isolated even when one carries a full-swing signal — a practical spec for RF or precision analog muxing.
Supply flexibility and package fit
The charge injection of 5 pC minimizes glitch energy when switching — relevant for sample-and-hold or DAC output multiplexing.
Active lifecycle and compliance
The 250 pA max leakage current keeps signal offset low across temperature.
