The 60 Ohm max on-resistance sets the insertion loss floor for the signal path — at DC this is a simple voltage divider with the load impedance, but at higher frequencies the 8 pF channel capacitance (CS(off), CD(off)) starts to dominate the off-isolation roll-off. Switching times are 100 ns max for turn-on and 75 ns max for turn-off, which means the part can handle audio-rate multiplexing and low-speed data switching without introducing timing skew between channels. The 800 mOhm channel-to-channel on-resistance matching keeps the gain error consistent when switching between two signal sources of the same impedance. ## Supply flexibility and leakage budget The 100 pA max off-leakage current (IS(off)) means the switch does not load the signal source when the channel is deselected; in a high-impedance sensor front-end this leakage is negligible compared to the bias current of a typical CMOS op-amp. Charge injection is rated at 1 pC typical. When the switch transitions from on to off, this charge dumps onto the load capacitance — for a 10 pF sample-and-hold cap the resulting voltage step is 100 mV, which may matter in precision analog paths. ## Crosstalk and signal integrity at 1 MHz Crosstalk is specified at -90 dB at 1 MHz. This figure tells you how much of the signal on one channel leaks into the deselected channel — at -90 dB the leakage is about 31.6 µV for a 1 V signal, which is below the noise floor of a 16-bit ADC at full scale. The 8-TSSOP/8-MSOP package (3.00 mm width) keeps the parasitic coupling between pins low; the 0.118-inch body is standard for this pin count.","metaTitle":"MAX4544CUA+ SPDT Analog Switch, 60 Ohm, 8-uMAX/uSOP","metaDescription":"Active-production SPDT analog switch from Analog Devices. 60 Ohm on-resistance, -90dB crosstalk at 1MHz, 1pC charge injection. 8-uMAX/uSOP package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Package":"Tube","Crosstalk":"-90dB @ 1MHz","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","Switch Circuit":"SPDT","lifecycle_stage":"eol_hot","Charge Injection":"1pC","Number of Circuits":"1","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"8-uMAX/uSOP","On-State Resistance (Max)":"60Ohm","Switch Time (Ton, Toff) (Max)":"100ns, 75ns","Voltage - Supply, Single (V+)":"2.7V ~ 12V","Current - Leakage (IS(off)) (Max)":"100pA","Multiplexer/Demultiplexer Circuit":"2:1","Channel Capacitance (CS(off), CD(off))":"8pF, 8pF","Channel-to-Channel Matching (ΔRon)":"800mOhm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.38","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.38000","currency":"USD"},{"qty":10,"price":"$2.14100","currency":"USD"},{"qty":25,"price":"$2.02000","currency":"USD"},{"qty":100,"price":"$1.72100","currency":"USD"},{"qty":250,"price":"$1.61600","currency":"USD"},{"qty":500,"price":"$1.41400","currency":"USD"},{"qty":1000,"price":"$1.17160","currency":"USD"},{"qty":2500,"price":"$1.09080","currency":"USD"},{"qty":5000,"price":"$1.05040","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"How do I get current pricing and availability for MAX4544CUA+?","answer":"Submit an RFQ through this listing."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX4544CUA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX4544CUA when reusing this data.
