Manufacturer:TOS Description:The SSM2402/SSM2412 are dual analog switches designed spe- cifically for high performance audio applications. Distortion and noise are negligible over the full audio operating range of 20 Hz to 20 kHz at signal levels of up to 10 V rms. The SSM2402/ SSM2412 offer a monolithic integrated alternative to expensive and noisy relays or complex discrete JFET circuits. Unlike conven- tional general-purpose CMOS switches, the SSM2402/SSM2412 provide superb fidelity without audio clicks during switching. Conventional TTL or CMOS logic can be used to control the switch state. No external pull-up resistors are needed. A T configuration provides superb OFF-isolation and true bilateral operation. The analog inputs and outputs are protected against overload and overvoltage. An important feature is the guaranteed break-before-make for all units, even IC-to-IC. In large systems with multiple switching channels, all separate switching units must open be- fore any switch goes into the ON-state. With the SSM2402/ SSM2412, you can be certain that multiple circuits will all break-before-make. The SSM2402/SSM2412 represent a significant step forward in audio switching technology. Distortion and switching noise are significantly reduced in the new SSM2402/SSM2412 bipolar- JFET switches relative to CMOS switching technology. Based on a new circuit topology that optimizes audio performance, the SSM2402/SSM2412 make use of a proprietary bipolar- JFET process with thin-film resistor network capability. Nitride capacitors, which are very area efficient, are used for the propri- etary ramp generator that controls the switch resistance transi- tion. Very wide bandwidth amplifiers control the gate-to-source voltage over the full audio operating range for each switch. The ON-resistance remains constant with changes in signal amplitude and frequency, thus distortion is very low, less than 0.01% max. The SSM2402 is the first analog switch truly optimized for high-performance audio applications. For broadcasting and other switching applications which require a faster switching time, we recommend the SSM2412a dual analog switch with one-third of the switching time of the SSM2402. |
