With a maximum on-resistance of 35 Ohm, it is designed for low-distortion switching of analog signals in applications such as audio routing, data acquisition, instrumentation, and test equipment. The part operates from either a dual supply of ±4.5 V to ±20 V or a single supply of 10 V to 30 V, giving the designer flexibility to match existing rail voltages without extra level translation. ## Switching speed and charge injection – what they mean for your signal path Turn-on time is 175 ns max, turn-off 145 ns max. That is fast enough for audio-band multiplexing, relay replacement, and low-frequency analog switching, but not intended for high-speed digital or RF paths where sub-10 ns switching is required. Charge injection is 3 pC typ – a moderate figure that can cause a glitch on the output when switching; in high-impedance sample-and-hold circuits or precision integrators, budget for a settling-time penalty or add a downstream buffer. ## Crosstalk and channel matching – isolation in multi-channel designs Crosstalk is -85 dB at 1 MHz. Channel-to-channel on-resistance matching is 2 Ohm max. ## Leakage and capacitance – impact on high-impedance nodes Off-state leakage current is 250 pA max, negligible in most circuits but worth noting if the switch is used in a high-impedance sensor interface or a long-hold sample-and-hold where picoamp-level leakage can cause droop. Channel capacitance (source off, drain off) is 8 pF each – a moderate load that will not significantly load a 10 kOhm source but will roll off bandwidth above 10 MHz. ## Active lifecycle and sourcing posture The MAX319CPA+ carries an active product status and is ROHS3 compliant. For a BOM line that needs a through-hole SPDT switch with wide supply range, this part is a stable choice.","metaTitle":"Maxim Integrated MAX319CPA+ SPDT Analog Switch, 35 Ohm","metaDescription":"Maxim MAX319CPA+ SPDT analog switch, 35 Ohm max on-resistance, ±4.5V to ±20V dual or 10V to 30V single supply, 8-PDIP, active lifecycle.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Package":"Tube","Crosstalk":"-85dB @ 1MHz","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","Switch Circuit":"SPDT","lifecycle_stage":"eol_hot","Charge Injection":"3pC","Number of Circuits":"1","Operating Temperature":"0°C ~ 70°C (TA)","Supplier Device Package":"8-PDIP","On-State Resistance (Max)":"35Ohm","Voltage - Supply, Dual (V±)":"±4.5V ~ 20V","Switch Time (Ton, Toff) (Max)":"175ns, 145ns","Voltage - Supply, Single (V+)":"10V ~ 30V","Current - Leakage (IS(off)) (Max)":"250pA","Multiplexer/Demultiplexer Circuit":"2:1","Channel Capacitance (CS(off), CD(off))":"8pF, 8pF","Channel-to-Channel Matching (ΔRon)":"2Ohm (Max)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.05","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.05000","currency":"USD"},{"qty":10,"price":"$7.27500","currency":"USD"},{"qty":25,"price":"$6.93600","currency":"USD"},{"qty":100,"price":"$6.02260","currency":"USD"},{"qty":250,"price":"$5.75196","currency":"USD"},{"qty":500,"price":"$5.24442","currency":"USD"},{"qty":1000,"price":"$4.56772","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3f2c9069512011856e6089b042406c85.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does MAX319CPA+ support dual supply voltages?","answer":"Yes, the MAX319CPA+ operates from a dual supply of ±4.5 V to ±20 V.
