FSA1153UCX

Analog Switches, Multiplexers, Demultiplexers Overview

The FSA1153UCX is a single-channel, double-pole triple-throw (DP3T) analog switch manufactured by onsemi. It operates within a supply voltage range of 2.7 V to 5.5 V and features a maximum on-resistance of 2 ohms with a channel-to-channel matching of 200 milliohms. The device supports a -3 dB bandwidth of 500 MHz and exhibits low leakage current, with a maximum off-state leakage of 100 nA. Switching times are characterized by a typical turn-on time of 80 µs and a typical turn-off time of 400 ns. It is housed in a compact 12-WLCSP package measuring 1.41 x 1.575 mm and functions reliably across an ambient temperature range of -40°C to +85°C.
