“TS3A5223是一个高速双模拟开关，具有提前关断和双向信号交换功能。 TS3A5223可以当做双2:1多路复用器，或1:2的双解复用器使用。
”The TS3A5223 is a high-speed dual analog switch with break-before-make and bi-directional signal switching capability. The TS3A5223 can be used as a dual 2:1 multiplexer or a 1:2 dual de-multiplexer.
The TS3A5223 offers very low ON resistance, very low THD, channel-to-channel crosstalk and very high OFF isolation. These features make TS3A5223 suitable for application in Audio signal routing and switching applications.
The TS3A5223 control logic supports 1.0V-3.6V CMOS logic levels. The logic interface allows direct interface with a wide range of CPUs and microcontrollers without increasint the current drawn from supply (ICC) and thus lowering power consumption.
Features
Low ON Resistance Switches 0.45 Ω (Typical) at 3.6V 0.85 Ω(Typical) at 1.8V Wide Supply Range: 1.65 V to 3.6 V 1.0 V Compatible Logic Interface High Switch Bandwidth 80 MHz 0.01% THD Across Entire Band Specified min Break-before-make Bi-directional Switching*–75 dB Channel-to-Channel Cross Talk *–70 dB Channel-to-Channel OFF Isolation of Very Low Power Dissipation and Leakage Currents
Very Small QFN-10 Package: 1.8mm × 1.4mm ESD Protection on all Pins 2kV HBM, 500 V CDM
