The onsemi FSA1257AL8X is a dual pole, single throw (SPST), normally closed analog switch. This device features a low on-resistance of 1.15 Ohms maximum, with channel-to-channel matching of 60 mOhms. Designed for single supply operation from 2.7V to 5.5V, it offers a -3dB bandwidth of 300MHz. The FSA1257AL8X exhibits low leakage current of 2nA typically and minimal charge injection of 20pC. Crosstalk is rated at -100dB at 1MHz, with channel capacitance at 11.5pF. Switching times for this component are a maximum of 35ns turn-on and 15ns turn-off. The FSA1257AL8X is packaged in an 8-MicroPak™ (8-UFQFN) and supplied on tape and reel. This component is suitable for applications in consumer electronics and industrial systems.
