aAM3104 ULTRA LOW POWER, 4-CHANNEL CMOS ANALOG MULTIPLEXER The aAM3104 is a precision CMOS analog multiplexer offering low on-resistance of less than 4Ω, with better than 0.4Ω matching between channels and extremely flat resistance over the specified analog input voltage range of less than 1.2Ω.The aAM3104 has very fast enable switching speed of less than 20nS over the full operating temperature range of -40°C to 85°C. The aAM3104 also consumes a minimal amount of power, making them ideal for portable equipment. Pin Configuration The aAM3104 connects 1-of-4 inputs to a common output by control of a 2-bit binary address. An enable pin disconnects all inputs from the output. The part is available in a 10-contact, leadless QFN package and operates over the range from 1.8V to 5.5V.
