Switching is fast — 130 ns turn-on, 75 ns turn-off — and the charge injection is a low 5 pC, which matters when you are multiplexing a sample-and-hold or a precision DAC reference. The part runs on a single supply from 2.7 V to 15 V, or on dual supplies from ±2.7 V to ±8 V, giving flexibility for bipolar signal chains. The -88 dB crosstalk at 1 MHz tells you the channels stay isolated well into the low-MHz range, so it fits audio routing, data acquisition front-ends, and ATE pin electronics where channel bleed cannot be tolerated. ## Crosstalk and isolation — what -88 dB at 1 MHz buys you The -88 dB crosstalk at 1 MHz means feedthrough into an off channel is 88 dB down.","metaTitle":"MAX394EUP+ Analog Switch, SPDT, 4-Circuit, 35Ohm, 20-TSSOP","metaDescription":"MAX394EUP+ precision analog switch, 4x SPDT, 35Ohm on-resistance, -88dB crosstalk @ 1MHz.

Pinouts differ — the TSSOP version adds two no-connect pins. The electrical specs (35 ohm on-resistance, -88 dB crosstalk, 130 ns switching) are identical between the two. Choose the package that matches your board layout."},{"question":"Can I use MAX394EUP+ for audio switching?","answer":"Yes. The -88 dB crosstalk at 1 MHz and low charge injection of 5 pC make it suitable for line-level audio routing, including balanced signals with dual supplies. The 35 ohm on-resistance adds about 0.15 dB of loss into a 10 kohm load — negligible in most audio paths."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX394EUP","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX394EUP when reusing this data.
