TS5A22366 Dual SPDT Analog Switch The Texas Instruments TS5A22366 dual single-pole double-throw (SPDT) analog switch is designed to operate from 2.25 V to 5.5 V and features negative signal capability that allows signals below ground to pass through the switch without distortion. The break-before-make feature of the TI TS5A22366 dual SPDT analog switch prevents signal distortion during the transferring of a signal from one path to another. Low ON-state resistance, excellent channel-to-channel ON-state resistance matching, and minimal total harmonic distortion (THD) performance are ideal for audio applications. The TI TS5A22366 analog switch is available is a ultra small 1.6 mm × 1.2 mm wafer-chip-scale package (WCSP) (0.4 mm pitch) and in a 2 mm × 1.5 mm quad flat (QFN) package (0.5 mm pitch).
