16:2 analog multiplexer with 60 MHz bandwidth
The MAX14661ETI+ from Analog Devices is a 16:2 multiplexer/demultiplexer that routes one of sixteen analog inputs to a common output pair. The 8 Ohm max on-resistance with 250 mOhm channel-to-channel matching keeps the signal path impedance consistent across all channels, which matters when the downstream ADC or amplifier expects a stable source impedance. The -3 dB bandwidth of 60 MHz and crosstalk of -80 dB at 1 MHz mean this part handles video-rate or high-speed analog signals without bleeding between channels.
Switching speed and leakage budget
Typical switch times are 13 µs turn-on and 5 µs turn-off, which sets the channel scan rate — scanning all 16 channels sequentially takes roughly 208 µs plus settling time. The max off-leakage current is 50 nA per channel, so the total leakage into the common output from all 15 off-channels sums to under 0.75 µA at 25 °C.
