Each of the two independent SPST-NO circuits handles signals up to 300 MHz bandwidth with a maximum on-resistance of 25 ohms. Channel-to-channel matching holds within 200 milliohms, and crosstalk between channels is rated at -108 dB at 1 MHz — clean enough for audio-path routing or precision analog multiplexing where bleed between channels would show up as noise or offset.
The dual SPST-NO switch with 25 ohm on-resistance, 300 MHz bandwidth, and -108 dB crosstalk is suited for audio signal routing, precision analog multiplexing, data acquisition front-ends, and general-purpose signal switching in industrial temperature environments.
