SPDT switch with 35 Ohm on-resistance and wide supply range
The Maxim Integrated DG419LEUA+T is a single-pole double-throw (SPDT) analog switch in an 8-uMAX/uSOP package. It handles signal routing with a maximum on-resistance of 35 Ohm and channel-to-channel matching within 100 mOhm.
Supply voltage — what it means for the BOM
The dual-supply range of ±4.5 V to ±20 V covers standard analog rails. If your board only has a single positive rail, the 9 V to 36 V single-supply mode works.
Package and footprint
The 8-uMAX/uSOP (3.00 mm width, 0.118" pitch) is a common small-outline footprint shared with many Maxim analog switches.
Lifecycle and compliance
It is ROHS3 compliant, so it passes the current EU restriction directive without an exemption. For BOM-freeze planning, this part is a low-risk line item: no looming EOL, no lead-time shock from a phase-out.
