Product details

Package and mounting

The LPV821DBVR: Its 1.5 µV input offset voltage and 650 nA supply current put it in the nanopower precision class — the kind of part you reach for when a battery-powered sensor node needs to amplify a thermocouple or bridge signal without burning the sleep budget. The 8 kHz gain-bandwidth product and 0.0033 V/µs slew rate confirm this is a DC-optimised amplifier: it will not track a 1 kHz sine wave cleanly, but it will hold a microvolt-level DC reading year after year with minimal drift.

Rail-to-rail output swing gives you the full ADC input range when the supply is tight.

Frequently asked questions

What is LPV821DBVR equivalent?

The closest functional second-source candidate is the TLV9351IDCKR, but that part is a general-purpose amplifier with 3.5 MHz GBW and 350 µV offset — a different performance tier. For a true zero-drift replacement with similar nanopower draw, the OPA333 (also zero-drift) is a common cross-shop, though its supply current is roughly 10× higher. No pin-compatible drop-in exists; verify the circuit's bandwidth and supply budget before swapping.

Can LPV821DBVR be used in sensor applications?

Yes — the 1.5 µV offset and 7 pA input bias make it well suited for precision sensor conditioning: thermocouple amplifiers, bridge transducers, photodiode front-ends, and battery-monitoring circuits. The 650 nA supply current keeps the signal chain alive in always-on sensing without draining the battery.

What is LPV821DBVR's slew rate?

0.0033 V/µs. This is a DC-precision amplifier — it will not track audio or fast-changing signals. Use it for steady-state or slowly varying DC measurements.
