The SSM2404 integrates four SPST analog switches in a single 20-pin package. Developed specifically for high performance audio applications, distortion and noise are negligible over the full operating range of 20 Hz to 20 kHz. With very low charge injection of 35 pC, "clickless" audio switching is possible, even under the most demanding conditions. Switch control is realized by conventional TTL or CMOS logic. Guaranteed "break-before-make" operation assures that all switches in a large system will open before any switch reaches the ON state.
