2 What is Analog Switch? Ideal Switch: Input signal applied to the left I/O results in an identical output signal at the right I/O. The switches referred to in this presentation are CMOS FET Switches. MOSFET switches are small, fast, easy-to-control and consume little power.

3 MOSFET Ron vs. VIN Curve Large Ron change with higher amplitude signals Low flat Ron over entire 0 to V+ signal range but higher Con

4 Specification of Analog Switch Ron: Ron contributes to signal loss and degradation. Low- Ron switches have longer on and off periods. As Ron increases the overall bandwidth decreases due to the capacitance of the device. For audio signals they may not be a problem, but should be considered for higher frequency analog signals. Ron flatness: Ron flatness describes the variation of Ron versus signal range for a single channel, it contribute to the THD. Bandwidth: Bandwidth or insertion loss of the switch determines the maximum frequency that can be passed through the device without significant signal loss. OFF Isolation: a measure of the ability of the multiplexer to block ac signals in the off state. Crosstalk: Crosstalk is the amount of signal cross coupling from an off analog input to the output of another on channel output. it is basically channel-tochannel isolation and occurs due to the off state parasitic capacitances of the multiplexer

36 Low-ICCT Analog Switches for Ultra-Portable Designs I Most standard analog switches specify only ICC consumption of the typical condition where the input control voltage is equal to the supply voltage. This has caused confusion among many system designers who were surprised to find milliamps of current as they migrated to lower-voltage ASICs. Low-ICCT analog switches are designed to operate in this type of application.

37 Low-ICCT Analog Switches for Ultra-Portable Designs II Vcc=3.3V General Switch VIL of General Switch:0.3Vcc VIL of UM3157 VIH of UM3157 VIH of General Switch:0.7Vcc About 300uA About 100uA UM3157 have a expanded input voltage range, lower-icct within the whole input voltage range.

38 T-Switch Configuration T-Switch Improve Channel Isolation The T-switch configuration attenuates High frequencies that couple through the stray capacitance between the source and the drain of an open (off) switch to achieve Low Cross Talk.

39 Terminal Resistance Symbols with Noise Termination Resistors Termination Resistor reduce noise when floating A internal shut resistors that automatically discharge the capacitance at the NO and NC terminals when they are not connected. This reduces click-and-pop noises that occur when switching audio signals between precharged points.
