80V common-mode — what it means on a 48V rail
The INA271AQDRZF is a current-sense amplifier from Texas Instruments rated for 80V common-mode input, covering both low-side and high-side sensing. That 80V headroom matters when you are monitoring current on a 48V industrial bus or a 24V motor drive with transient spikes — the part stays linear without a voltage divider eating into your dynamic range.
For a current-sense amp that handles up to 80V, that is useful if your panel design has a multi-year production run.
