It switches analog or digital signals up to the supply rails with a maximum on-resistance of 3.5kOhm and channel-to-channel matching of 70Ohm — tight enough for multiplexing sensor inputs or gain-setting resistors where the absolute R_on matters less than the ratio between channels. Charge injection is rated at 2pC typical, and off-leakage maxes out at 10pA, so it won't glitch a sample-and-hold capacitor or bleed down a high-impedance node. The supply range accepts either a single +10V to +30V rail or dual ±5V to ±18V rails, which covers the ±15V supplies common in ATE and bench instrumentation. ## Package and mounting The wide SOIC footprint is common for multi-channel analog switches and op-amps, so it fits a standard PCB land pattern without surprises.","metaTitle":"MAX329EWE+T Analog Devices SP4T Analog Switch, 3.5kOhm","metaDescription":"MAX329EWE+T is an active SP4T analog switch with 3.5kOhm max on-resistance, 2pC charge injection, and -40°C to +85°C range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Package / Case":"16-SOIC (0.295\\\", 7.50mm 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)":"3.5kOhm","Voltage - Supply, Dual (V±)":"±5V ~ 18V","Switch Time (Ton, Toff) (Max)":"1.5µs, 1µs","Voltage - Supply, Single (V+)":"10V ~ 30V","Current - Leakage (IS(off)) (Max)":"10pA","Multiplexer/Demultiplexer Circuit":"4:1","Channel Capacitance (CS(off), CD(off))":"1.8pF, 8pF","Channel-to-Channel Matching (ΔRon)":"70Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$19.47","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$19.47000","currency":"USD"},{"qty":10,"price":"$17.89500","currency":"USD"},{"qty":25,"price":"$17.15280","currency":"USD"},{"qty":100,"price":"$15.11300","currency":"USD"},{"qty":250,"price":"$14.37128","currency":"USD"},{"qty":500,"price":"$13.44412","currency":"USD"},{"qty":1000,"price":"$12.33149","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX328-MAX329.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the on-resistance of MAX329EWE+T?","answer":"The maximum on-resistance is 3.5kOhm per channel, with channel-to-channel matching of 70Ohm.
