Product details
Frequently asked questions
What is the LTC2946IDE-1#PBF operating voltage range?
The supply voltage range is 2.7 V to 100 V. The 100 V maximum lets it monitor 48 V telecom rails, 72 V industrial buses, or 96 V battery strings directly without an external divider.
What is the replacement or equivalent for LTC2946IDE-1#PBF?
The closest functional equivalent is the LTC2946IDE#PBF — same die, same 0.4% error, same 2.7 V to 100 V range, but shipped in Tube instead of Bulk. The LTC2946HMS-1#PBF extends the temperature range to 125°C with a slightly wider 0.5% error spec. Neither is a direct pin-compatible second source; verify the package and shipping medium against your BOM.
