Each switch routes one of four analog inputs to a common output, with a break-before-make switching action that prevents momentary shorting between channels. The 100 Ohm max on-resistance is the headline figure: it sets the voltage drop across the switch at a given load current and directly affects the accuracy of sampled analog signals. Typical applications include data-acquisition front-ends, audio routing, test equipment, and industrial sensor multiplexing where multiple analog channels share one ADC or amplifier. The -40°C to +85°C operating range covers industrial and outdoor telecom enclosures. ## Signal integrity specs that matter Crosstalk is rated at -92 dB at 100 kHz — that is the isolation between two active channels. ## Lifecycle and sourcing The MAX309ESE+T carries an Active lifecycle status and is ROHS3 compliant.","metaTitle":"MAX309ESE+T Analog Switch IC, SP4T x 2, 100Ohm, 16-SOIC","metaDescription":"MAX309ESE+T is a dual SP4T analog multiplexer/switch with 100Ohm max on-resistance, -92dB crosstalk at 100kHz, and 5V to 30V single supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Crosstalk":"-92dB @ 100kHz","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.154\\\", 3.90mm Width)","Switch Circuit":"SP4T","lifecycle_stage":"eol_hot","Charge Injection":"2pC","Number of Circuits":"2","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"16-SOIC","On-State Resistance (Max)":"100Ohm","Voltage - Supply, Dual (V±)":"±5V ~ 20V","Switch Time (Ton, Toff) (Max)":"150ns, 150ns","Voltage - Supply, Single (V+)":"5V ~ 30V","Current - Leakage (IS(off)) (Max)":"750pA","Multiplexer/Demultiplexer Circuit":"4:1","Channel Capacitance (CS(off), CD(off))":"3pF, 26pF","Channel-to-Channel Matching (ΔRon)":"1.5Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$10.53","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$10.53000","currency":"USD"},{"qty":10,"price":"$9.51100","currency":"USD"},{"qty":25,"price":"$9.06880","currency":"USD"},{"qty":100,"price":"$7.87440","currency":"USD"},{"qty":250,"price":"$7.52048","currency":"USD"},{"qty":500,"price":"$6.85688","currency":"USD"},{"qty":1000,"price":"$5.97213","currency":"USD"},{"qty":2500,"price":"$5.75094","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX308-MAX309.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the on-resistance of MAX309ESE+T?","answer":"The max on-resistance is 100 Ohm, with channel-to-channel matching of 1.5 Ohm max.
