The MAX4719EUB+ is a dual SPDT analog switch from Analog Devices, meaning it contains two independent single-pole double-throw switches in one package — each switch routes a common pin to one of two outputs. It is built for multiplexing or signal routing in audio, data acquisition, and test equipment where signal integrity matters. Key parametrics: 20 Ohm max on-resistance, 300 MHz -3dB bandwidth, and -110 dB crosstalk at 1 MHz. The on-resistance stays flat across the 1.8V to 5.5V single supply range, which means the insertion loss does not shift much when the rail droops. ## On-resistance and supply voltage range On-resistance is 20 Ohm max — that is the resistance between the common pin and the selected output when the switch is on. For a 1V signal into a 10 kOhm load, the voltage drop across the switch is under 2 mV, negligible in most analog chains. Supply voltage runs from 1.8V to 5.5V single supply. The 1.8V floor means it works with modern low-voltage logic like 1.8V CMOS, while the 5.5V ceiling covers legacy 5V systems. No dual supply needed — one rail does it all. ## Package, mounting, and temperature grade Housed in a 10-uMAX/uSOP package (3.00 mm body width, 0.118-inch pitch), surface-mount only. The small footprint is good for dense boards, but the 0.50 mm pin pitch means a standard fine-tip iron works for hand rework — no hot-air station required if you have decent solder wick. The charge injection is 18 pC typical — low enough that glitch energy on switching stays under a few millivolts into a 10 pF load. Sourced per RFQ against your BOM quantity. ## Switching speed and leakage Turn-on time is 80 ns max, turn-off is 40 ns max. That 2:1 ratio means the switch opens faster than it closes — useful for break-before-make sequencing to prevent momentary shorting of two signal paths. Off-state leakage is 500 pA max at 25°C. In a high-impedance circuit like a pH probe or photodiode amplifier, that leakage is well below the sensor bias current, so it will not corrupt the measurement.","metaTitle":"MAX4719EUB+ SPDT Analog Switch - 20 Ohm, 300MHz, 10-uMAX","metaDescription":"MAX4719EUB+ from Analog Devices: dual SPDT switch, 20 Ohm max on-resistance, 300MHz bandwidth, -110dB crosstalk at 1MHz.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Sensors & Transducers"],"specifications":{"Package":"Tube","Crosstalk":"-110dB @ 1MHz","Mounting Type":"Surface Mount","-3db Bandwidth":"300MHz","Package / Case":"10-TFSOP, 10-MSOP (0.118\\\", 3.00mm Width)","Switch Circuit":"SPDT","lifecycle_stage":"eol_hot","Charge Injection":"18pC","Number of Circuits":"2","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"10-uMAX/uSOP","On-State Resistance (Max)":"20Ohm","Switch Time (Ton, Toff) (Max)":"80ns, 40ns","Voltage - Supply, Single (V+)":"1.8V ~ 5.5V","Current - Leakage (IS(off)) (Max)":"500pA","Multiplexer/Demultiplexer Circuit":"2:1","Channel Capacitance (CS(off), CD(off))":"9pF","Channel-to-Channel Matching (ΔRon)":"150mOhm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.67","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$3.67000","currency":"USD"},{"qty":10,"price":"$3.29300","currency":"USD"},{"qty":25,"price":"$3.11320","currency":"USD"},{"qty":100,"price":"$2.69820","currency":"USD"},{"qty":250,"price":"$2.55984","currency":"USD"},{"qty":500,"price":"$2.29694","currency":"USD"},{"qty":1000,"price":"$1.93718","currency":"USD"},{"qty":2500,"price":"$1.84032","currency":"USD"},{"qty":5000,"price":"$1.77114","currency":"USD"}]},"links":{"datasheetUrl":"https://datasheets.maximintegrated.com/en/ds/MAX4719.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the switch topology and number of circuits for the MAX4719EUB+?","answer":"It is a dual SPDT (single-pole double-throw) switch — two independent 2:1 multiplexer/demultiplexer circuits in one package.
