Quad SPST-NO analog switch for precision signal routing
The Maxim MAX392EUE+ is a quad SPST-NO analog switch in a 16-TSSOP package. Each of the four independent switches handles signals with a maximum on-resistance of 35 Ohm, and the channel-to-channel matching holds within 300 mOhm — useful when you are routing multiple channels through the same board and want consistent attenuation across paths. The -85 dB crosstalk at 1 MHz keeps channel bleed low enough for audio-frequency multiplexing and moderate-speed data acquisition. Switching is fast — 130 ns turn-on, 75 ns turn-off — so you can scan multiple sensor inputs or reconfigure gain networks without missing a sample window. The 2 pC charge injection is low enough that downstream sample-and-hold circuits see minimal glitch.

Package and handling in the field
Surface-mount only; no socket option, so plan for a rework station or a steady hand if swapping in the field.
