The -85 dB crosstalk at 1 MHz tells you adjacent channels stay isolated; a signal on one path leaks less than 0.006% into the neighbouring channel, which matters for precision analog multiplexing or multi-channel data acquisition. Charge injection is rated at 0.5 pC typical. That is the tiny packet of charge the switch dumps onto the output when it toggles. In a sample-and-hold or a DAC output multiplexer, 0.5 pC into a 10 pF hold capacitor creates a 50 mV glitch — small enough to settle before the next conversion cycle in most 12-bit systems. ## Package, supply, and temperature — what fits the board Housed in a 20-lead LFCSP (4x4 mm) with an exposed pad — the 20-WFQFN package variant. The pad also gives you a solid mechanical anchor during rework — a hot-air station at 300°C with a fine nozzle lifts the part cleanly if you preheat the board from the bottom to 100°C first. Supply range covers single 5 V to 16.5 V or dual ±5 V to ±16.5 V. The 190-ohm max on-resistance is specified at 25°C with a ±15 V supply — it rises with temperature and drops as supply voltage increases. Channel-to-channel matching of 3.5 ohm means the four switches track each other within that spread, important for gain-matching in a multiplexed PGA front-end. The switch time (140 ns on, 45 ns off) is specified at 25°C with a 5 V supply; expect it to slow by roughly 20% at 125°C and speed up slightly at cold. The 100 pA max off-leakage and 1.7/1.8 pF channel capacitance keep the signal path clean at high impedance. ## Sourcing and compliance — active, RoHS3, reel The closest functional peer is the ADG1234YRUZ-REEL7 — same die, same quad SPDT topology, same 900 MHz bandwidth and -85 dB crosstalk, but packaged in a 20-TSSOP instead of the LFCSP. The pinout differs between the two packages, so a board spin is required to swap them. The ADG1233YCPZ-REEL7 is a triple (3-circuit) version in the same LFCSP footprint, useful if one channel is unused.","metaTitle":"Analog Devices ADG1234YCPZ-REEL7 Quad SPDT Switch, 900MHz","metaDescription":"Active-production ADG1234YCPZ-REEL7 quad SPDT analog switch from Analog Devices. 900MHz bandwidth, -85dB crosstalk, 0.5pC charge injection.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Crosstalk":"-85dB @ 1MHz","Mounting Type":"Surface Mount","-3db Bandwidth":"900MHz","Package / Case":"20-WFQFN Exposed Pad, CSP","Switch Circuit":"SPDT","lifecycle_stage":"eol_hot","Charge Injection":"0.5pC","Number of Circuits":"4","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"20-LFCSP (4x4)","On-State Resistance (Max)":"190Ohm","Voltage - Supply, Dual (V±)":"±5V ~ 16.5V","Switch Time (Ton, Toff) (Max)":"140ns, 45ns","Voltage - Supply, Single (V+)":"5V ~ 16.5V","Current - Leakage (IS(off)) (Max)":"100pA","Multiplexer/Demultiplexer Circuit":"2:1","Channel Capacitance (CS(off), CD(off))":"1.7pF, 1.8pF","Channel-to-Channel Matching (ΔRon)":"3.5Ohm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$9.56","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$9.56000","currency":"USD"},{"qty":10,"price":"$8.63700","currency":"USD"},{"qty":25,"price":"$8.23560","currency":"USD"},{"qty":100,"price":"$7.15100","currency":"USD"},{"qty":250,"price":"$6.82960","currency":"USD"},{"qty":500,"price":"$6.22696","currency":"USD"},{"qty":1500,"price":"$5.68500","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/429ec507ea772f64db8e7426d940879a.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the closest functional second-source for ADG1234YCPZ-REEL7?","answer":"The ADG1234YRUZ-REEL7 uses the same die with identical electrical specs (900 MHz bandwidth, -85 dB crosstalk, 0.5 pC charge injection) but in a 20-TSSOP package — the pinout differs, so a board layout change is required."},{"question":"What compliance documentation does Analog Devices provide for ADG1234YCPZ-REEL7?","answer":"RoHS3 compliant per the lifecycle record.
