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.
Single or dual supply operation is possible. Additional features
include –100 dB OFF isolation, –94 dB crosstalk and 28 W ON
resistance. Optional current-mode switching permits an
extended signal-handling range. Although optimized for large
load impedances, the SSM2404 maintains good audio
performance even under low load impedance conditions.
