The 210 MHz -3 dB bandwidth means this part passes analog signals well into the VHF range — suitable for ultrasound transducer beamforming, telecom baseband routing, or video signal switching where signal integrity above 100 MHz matters. ## On-resistance and signal path loss Maximum on-state resistance is 50 Ohm — this sets the insertion loss through the switch. For a 50 Ohm system, the switch adds roughly 6 dB of attenuation in the signal path; for higher impedance loads the loss drops proportionally. The single 12 V supply or dual ±5 V rails give flexibility to match the analog signal swing. With ±5 V the switch handles bipolar signals up to the supply rails, useful for ultrasound echoes that swing below ground. ## Package and rework considerations The exposed pad needs a solder paste stencil opening that matches the datasheet footprint; under the hot-air station the part reflows evenly if the pad is properly tinned. Pin 1 is marked by a chamfer on the top-left corner of the package. The 0.5 mm pitch QFN lands are on the bottom; alignment under reflow is self-centering if the paste deposit is consistent across all 32 pads. The wide range also suits automated test equipment where the switch sits near a heated device interface. Listed applications include telecommunications and ultrasound — both require the 210 MHz bandwidth and the non-blocking matrix topology to route multiple analog channels without crosstalk between paths. ROHS3 compliant per the manufacturer's declaration — no restricted substances above the threshold limits for EU and global markets.","metaTitle":"ADG2128YCPZ-REEL7 Analog Devices 12:8 Crosspoint Switch","metaDescription":"Analog Devices ADG2128YCPZ-REEL7 12:8 crosspoint switch, 210 MHz bandwidth, 50 Ohm R_on, 32-LFCSP.
