MAX14661 Beyond-the-Rails 16:2 Multiplexer¶
lbuild module: modm:driver:max14661
The MAX14661 is a serially controlled, dual-channel analog multiplexer allowing any of the 16 AB pins to be connected to either common pin (COMA, COMB) simultaneously in any combination. The device features Beyond-the-Rails capability so that ±5.5V signals can be passed with any single supply between +1.6V and +5.5V.
The serial control is selectable between I2C and SPI, both of which are implemented as separate transport layers so the same driver can be used with either bus.
