Features
* “CIickless” Bilateral Audio Switching Four SPST Switches in a 20-Pin Package Ultralow THD+N: 0.0008% @ 1 kHz (2 V rms, R L = 100 k ⍀) Low Charge Injection: 35 pC typ High OFF Isolation:
* 100 dB typ (RL = 10 k⍀ @ 1 kHz) Low Crosstalk:
* 94 dB typ (R L = 10 k⍀ @ 1 kHz) Low ON Resistance
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-ma
