The 100 Ohm max on-state resistance sets the insertion loss floor — in a 10 kOhm source impedance path, that 100 Ohm adds about 1% gain error, which is negligible for most 8-bit systems but worth budgeting for 12-bit+ precision chains. Crosstalk is specified at -90 dB at 100 kHz, meaning a full-swing signal on one channel couples less than 32 µV into an adjacent off-channel at that frequency. That figure holds up well for audio-frequency multiplexing or low-speed data acquisition where channel isolation matters more than raw switching speed. ## Charge injection and switching speed for sample-and-hold front ends Charge injection is 2 pC typical — when the switch opens, that charge dumps onto the sampling capacitor. For a 10 nF hold cap, the resulting voltage step is 200 µV, which is acceptable for 10-bit accuracy but starts to eat into the LSB budget at 12 bits. The 175 ns turn-on and 150 ns turn-off times (max) set the throughput ceiling: at 1 MHz switching, the on-time window is 1 µs minus 175 ns, leaving 825 ns for the signal to settle through the 100 Ohm path plus load capacitance. Supply flexibility is a practical advantage: single-supply operation from 2 V to 16 V, or dual supplies from ±2.7 V to ±8 V. ## Active lifecycle, ROHS3, and commercial temperature grade ROHS3 compliant, so it clears EU regulatory gates without an exemption certificate. The 16-SOIC footprint is a standard JEDEC outline, so PCB layout follows the familiar SOIC-16 land pattern with 1.27 mm pitch.","metaTitle":"MAX4051CSE+ Analog Devices 8:1 Mux, 100 Ohm, 16-SOIC","metaDescription":"MAX4051CSE+ 8:1 multiplexer/demultiplexer from Analog Devices. 100 Ohm on-resistance, -90 dB crosstalk at 100 kHz, 2 pC charge injection.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tube","Crosstalk":"-90dB @ 100kHz","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Charge Injection":"2pC","Number of Circuits":"1","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"16-SOIC","On-State Resistance (Max)":"100Ohm","Voltage - Supply, Dual (V±)":"±2.7V ~ 8V","Switch Time (Ton, Toff) (Max)":"175ns, 150ns","Voltage - Supply, Single (V+)":"2V ~ 16V","Current - Leakage (IS(off)) (Max)":"1nA","Multiplexer/Demultiplexer Circuit":"8:1","Channel Capacitance (CS(off), CD(off))":"2pF, 2pF","Channel-to-Channel Matching (ΔRon)":"12Ohm (Max)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.82","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.82000","currency":"USD"},{"qty":10,"price":"$5.22800","currency":"USD"},{"qty":25,"price":"$4.94240","currency":"USD"},{"qty":100,"price":"$4.28360","currency":"USD"},{"qty":250,"price":"$4.06388","currency":"USD"},{"qty":500,"price":"$3.64652","currency":"USD"},{"qty":1000,"price":"$3.07538","currency":"USD"},{"qty":2500,"price":"$2.92161","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4453ce6aa2b8517c9dba20dea5f02013.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the crosstalk specification of MAX4051CSE+?","answer":"Crosstalk is -90 dB at 100 kHz, which means a 1 V signal on one channel couples less than 32 µV into an adjacent off-channel at that frequency.
