Each of the four independent switches presents a maximum on-resistance of 4 Ohms, with channel-to-channel matching held to 200 mOhms — tight enough for precision gain-setting or multiplexing low-level analog signals without introducing offset errors between paths. Switching is fast: Ton 275 ns max, Toff 175 ns max, which keeps the throughput window open for 1 MHz+ sample rates in data acquisition or audio routing. Crosstalk between channels is specified at -60 dB at 1 MHz, giving clean separation for multi-channel sensor muxes or analog front ends. Supply range covers single +4.5 V to +36 V, or dual ±4.5 V to ±20 V. Charge injection is 300 pC typical. Operating temperature is 0°C to 70°C, so this is a commercial-grade part for indoor equipment, lab instruments, audio gear, or benchtop testers — not for automotive under-hood or outdoor telecom cabinets. The 16-SOIC footprint (0.154\" body width, 3.90 mm) is a standard surface-mount package that routes easily on two-layer boards. ## What the key ratings mean for the BOM The 4 Ohm max on-resistance keeps voltage drop across the switch below 4 mV per mA of signal current, which is negligible for most op-amp level signals. If you are switching a precision voltage reference or a DAC output, that 4 Ohm in series with the load forms a voltage divider — account for it in the gain budget, or use the matching spec (200 mOhm max) to guarantee the error is consistent across channels. Off-leakage is 500 pA max. Channel capacitance is 34 pF. Dual-supply range is ±4.5 V to ±20 V. Single-supply range is 4.5 V to 36 V. ## Lifecycle and compliance The MAX4664CSE+ is listed as Active with a current lifecycle stage — no end-of-life notice, no last-time-buy window to plan around. ROHS3 compliant, so it passes the EU RoHS directive without exemption issues.","metaTitle":"MAX4664CSE+ 4-Channel SPST-NC Analog Switch, 4 Ohm, 16-SOIC","metaDescription":"Maxim MAX4664CSE+ quad SPST-NC analog switch, 4 Ohm max on-resistance, 275ns switching, -60dB crosstalk @ 1MHz. 16-SOIC, 0-70°C.

For a normally-closed quad with similar 4 Ohm RON, the MAX4664 is the direct part; sibling parts like the MAX4662 (SPST-NO) or MAX4665 (SPDT) differ in logic and pinout. Verify the switch-circuit topology before substituting."},{"question":"What is MAX4664CSE+'s crosstalk spec?","answer":"Crosstalk is rated at -60 dB at 1 MHz. This means a 1 Vpp signal on one channel couples less than 1 mV into an adjacent off-channel at 1 MHz — sufficient for 10-bit to 12-bit analog multiplexing at moderate frequencies."},{"question":"Is MAX4664CSE+ RoHS compliant?","answer":"Yes, it is ROHS3 compliant — no restricted substances above the exemption thresholds."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX4664CSE","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX4664CSE when reusing this data.
