FSA2258L10X

Analog Switches, Multiplexers, Demultiplexers Overview

The onsemi FSA2258L10X is a dual single-pole double-throw (SPDT) analog switch housed in a 10-MicroPak package. It operates within a supply voltage range of 1.65V to 4.3V and features a typical on-resistance of 500 milliohms with a maximum channel-to-channel matching of 80 milliohms. The device provides a -3dB bandwidth of 50MHz, charge injection of 25pC, and a maximum leakage current of 10nA. Switching times are specified at 55ns for turn-on and 30ns for turn-off, with an operating temperature range from -40°C to +85°C.
