MAX4649EKA+T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX4649EKA+T is a single-channel SPDT analog switch in an SOT-23-8 package. It operates on a single supply of 9V to 36V or dual supplies of ±4.5V to ±20V. The device features a maximum on-resistance of 45 Ohms with a channel-to-channel matching of 600 mOhm and RON flatness of 7 Ohms. Switching times are 130 ns for both turn-on and turn-off. Leakage current is 2 nA, charge injection is 2 pC, and power consumption is 75 uA. It supports rail-to-rail signals, offers -92 dB crosstalk at 1 MHz, and functions within a temperature range of -40°C to +85°C.
