Visão Geral
Description
LM2902QPWRQ1 is TI’s quad operational amplifier in a RoHS-compliant, lead-free package, providing four independent op-amps in one device. It’s designed for low-power, single-supply operation in battery-powered and signal-conditioning apps. Key points:
- Four amplifiers in one package; suitable for buffering, filtering, summing, and small-signal amplification.
- Input common-mode includes ground; outputs can swing close to the negative rail but are not rail-to-rail to the positive rail.
- Low per-channel quiescent current and a broad supply range for use across various environments.
- PWRQ1 suffix indicates RoHS-compliant packaging with good thermal performance.
Notes:
- Not rail-to-rail on inputs or outputs; consult datasheet for exact supply limits, input ranges, and output swing.
Common uses include sensor front-ends, active filters, and basic amplifiers in portable, industrial, or automotive electronics.

Equivalent
Do you need pin‑for‑pin, automotive (AEC‑Q100) drop‑in replacements or just functionally equivalent quad op‑amps? Also tell me the package (e.g., TSSOP‑14, VSSOP‑14) and supply/rail‑to‑rail requirements. I can then list exact cross‑references (TI, ON Semiconductor, ST, Microchip, ADI) and part numbers.
