What this SPDT switch brings to a precision signal chain
The ADG419BRMZ-REEL7 is a single-pole double-throw (SPDT) analog switch from Analog Devices, configured as a 2:1 multiplexer/demultiplexer in an 8-MSOP package. Its -90dB crosstalk at 1MHz means the off-channel bleeds less than 30 µV into the on-channel on a 3V signal — that's the difference between a clean multiplexed ADC reading and a ghosted one. The 35Ohm max on-resistance is consistent across the ±15V dual supply or 12V single supply range, so the voltage drop through the switch stays predictable whether you're routing ±10V analog signals or a 0-10V sensor output.
Package and board-fit for the 8-MSOP reel
Housed in an 8-MSOP (3.00mm width) package, the ADG419BRMZ-REEL7 lands on a footprint shared with the standard 8-TSSOP — the 0.65mm pitch demands a fine-tipped iron or a reflow profile that doesn't exceed the 260°C peak for lead-free solder. The Tape & Reel delivery suits automated pick-and-place; the Cut Tape option works for prototype runs.
Lifecycle and compliance posture
The ROHS3 compliance covers the current EU RoHS exemption set, so it ships into European builds without a waiver.
