Designed for operation between 1.65V to 5.5V Vcc, the new dual single pole double throw (SPDT) analog switch from Texas Instruments Inc. (TI) provides low power consumption and high-speed while maintaining excellent signal integrity. TI said this capability makes its new product ideal for applications such as analog signal routing, signal gating, and digital signal multiplexing/demultiplexing.

The TS5A23157 switch offers low power consumption (typical 1?A at 5.5V), low ON-state resistance (10 ohms) and excellent channel-to-channel on-state resistance matching (delta Ron). These features minimize the signal distortion and make it suitable for audio, video and other general purpose analog applications.

Additionally, the SPDT switch is capable of passing both analog and digital signals with amplitudes of up to V+ (peak) in either direction without clipping. Other features include Specified Break-Before-Make Switching that prevents inadvertent connection of two signal sources, low charge injection (7 pC), and low total harmonic distortion (0.01 percent).

The TS5A23157 is offered in the low profile TSSOP (MSOP-10) package. The TS5A23157DGSR is currently available to sample. Budgetary pricing for the TS5A23157DGSR is 63 cents in quantities of 1,000.
