The SSM2404 is a quad audio switch with low distortion, low charge injection, high switch isolation, low crosstalk, low switch resistance and low supply current.
The SSM2404 integrates four SPST analog switches in a single 20-pin package, specifically designed for high-performance audio applications. It features guaranteed break-before-make operation, low charge injection of 35 pC typical, and ultralow total harmonic distortion plus noise (THD+N) of 0.0008% at 1 kHz. The device supports both single and dual supply operation and is compatible with TTL and CMOS logic inputs.
| Total Harmonic Distortion Plus Noise (THD+N) | 0.0008% @ 1 kHz |
|---|---|
