TI Debuts Low-Power Dual SPDT Analog Switch for Portable Applications

9/7/2004 - Texas Instruments (TI) (NYSE: TXN) announced the release of a new low-power dual single pole double throw (SPDT) analog switch, the TS5A23157. Designed for operation between 1.65V to 5.5V Vcc, this device provides low power consumption and high-speed, while maintaining excellent signal integrity, making it ideal for applications such as analog signal routing, signal gating, and digital signal multiplexing/demultiplexing.

This device offers low power consumption (Typical 1uA at 5.5V), low ON-state resistance (10 ohms), excellent channel-to-channel on-state resistance matching (delta Ron). These features minimize the signal distortion and make it suitable for audio, video and numerous other general purpose analog applications. The TS5A23157 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 preventing inadvertent connection of two signals sources, low charge injection (7 pC), and low total harmonic distortion (0.01%).

Pricing and Availability
The TS5A23157 is offered in the space saving, low profile TSSOP (MSOP-10) package. The TS5A23157DGSR is currently available to sample. Budgetary pricing for the TS5A23157DGSR is set at $0.63 in quantities of 1,000.
