AMC3330-Q1

Voltage-sensing amplifier with integrated isolated power

High input impedance and a ±1V input range suit voltage-divider measurements, with integrated isolated DC/DC for low-side single-supply operation. It is not a low-millivolt shunt amplifier, and isolation withstand voltage is not the allowed signal amplitude.

LifecycleActive

In one sentence: Qualification is grounded in this TI product's documentation; no grade is inferred from temperature. An ordering table may show junction or variant-specific limits, which must be distinguished from ambient conditions. No TI functional-safety category was established in the reviewed product parameters/features. This does not prove that related documents are unavailable; do not infer ASIL or Compliant status.

Orderable variants (OPNs)

The GPN is for selection; the full OPN is for ordering. These examples were observed on the verification date, not live stock. Variants may differ in package, temperature, gain/threshold and, for PMICs, NVM/sequencing. Distinguish TA from TJ in the exact datasheet.

FAQ

Is 4250VRMS a continuous operating voltage?

No. It is a time-limited withstand-test rating. Review working voltage, transient rating, creepage and signal range separately.

Is it interchangeable with a low-level shunt amplifier?

Not on isolation alone. Its ±1V high-impedance input targets voltage signals; choose current-sensing devices against shunt drop, noise, gain and error budget.

How should I verify the AMC3330-Q1 orderable?

The page lists 1 OPN examples from official material checked on 2026-11-06. Match package, function options and temperature definitions; obtain live price/stock from TI or authorized distributors.
