, Inc.The MAX4651EUE+T is an Analog Switch IC manufactured by Analog Devices, Inc. It is a Low-Voltage 4 Ohm Quad Single Pole Single Throw (SPST) CMOS Analog Switches. The device is constructed in a tiny 8-pin Thin Shrink Small Outline Package (TSSOP) measuring just 2.9mm wide, 2.1mm high, and 0.65mm thick. The MAX4651EUE+T is a fully protected device made to operate from a 1.8V to 5.5V supply and able to switch signals up to 5V. High power-supply rejection ratio (PSRR) ensures that the switch maintains its output level even in the presence of large power supply disturbances, making it suitable for precision audio and medical applications. Ratio accuracy and linearity of the analog switches are excellent, with Off resistance at 3.5?, and current connectivity at 1.5mA. The switch is also very fast, with a tON of 19ns, tOFF of 28ns, and a tR/tF of 9ns and 10ns, respectively.
