Product details

Package and rework perspective

The ADG741BKSZ5-REEL7: Supplied in Tape & Reel (TR) or Cut Tape (CT), the reel quantity suits automated pick-and-place; the cut tape is fine for prototype runs or bench builds.

Switch performance and signal path

This is a single-pole single-throw normally-open (SPST-NO) switch with a 1:1 multiplexer/demultiplexer circuit — essentially a single series pass transistor. The 3 Ohm max on-state resistance (3 Ohm) means minimal voltage drop in the signal path; for a 1 V signal at 10 mA, the drop is under 30 mV. That matters for precision analog routing where every millivolt counts. The -3 dB bandwidth is 200 MHz, so this switch passes high-speed analog or digital signals up to that frequency without significant roll-off. Charge injection is 5 pC typical — when the switch opens, that injected charge can glitch a sample-and-hold capacitor; 5 pC is low enough for 12-bit settling in most audio or sensor front-ends. Switching times are 12 ns (on) and 8 ns (off) typical — fast enough for multiplexing at several megahertz. Channel capacitance is 17 pF on both source and drain sides, which combines with the load impedance to set the high-frequency corner; with a 50 Ohm load, the -3 dB point from capacitance alone is about 187 MHz, consistent with the 200 MHz bandwidth spec.

Supply and temperature range

The temperature range is -40°C to 85°C (TA) — industrial grade, so it works in factory-floor gear, outdoor telecom cabinets, or automotive cabin environments (not under-hood). Leakage current when off (IS(off)) is max 250 pA — negligible for most circuits, but in a high-impedance node (like a photodiode amplifier), that leakage adds to the dark current and may need compensation.

Analog Devices lists this part as Active (current production) and ROHS3 compliant.

Frequently asked questions

What is the closest functional second-source for ADG741BKSZ5-REEL7?

The ADG741BKSZ-REEL and ADG741BKSZ-REEL7 are electrically identical — same 3 Ohm on-resistance, 200 MHz bandwidth, 5 pC charge injection, and SC-70-5 package. The only difference is the reel diameter; they are drop-in replacements for each other on the same PCB.
