Analog Devices SSM2404
The SSM2404 integrates four SPST analog switches in a single 20-pin package. With very low charge injection of 35 pC, “clickless” audio switching is possible, even under the most demanding conditions. Although optimized for large load impedances, the SSM2404 maintains good audio performance even under low load impedance conditions.| Part No. | SSM2404 |
