The AD8502/AD8504 are low power, precision CMOS operational amplifiers featuring a maximum supply current of 1 μA per amplifier.
The AD8502 and AD8504 are precision CMOS operational amplifiers designed for battery‑powered portable applications. They feature a maximum supply current of 1 µA per amplifier, rail‑to‑rail input and output, and a typical input bias current of 10 pA. Their low offset voltage (3 mV) and wide supply range make them suitable for sensors, filters, and threshold detectors.
The datasheet provides detailed electrical characteristics, absolute maximum ratings, thermal data, and typical performance graphs. It also includes pin configurations for the 8‑lead SOT‑23 (AD8502) and 14‑lead TSSOP (AD8504) packages, as well as ordering information and mechanical dimensions.
| Supply current per amplifier (max) | 1 µA |
|---|---|
| Offset voltage (typical) | 3 mV |
| Supply voltage range | +1.8 V to +5.5 V (single) or ±0.9 V to ±2.75 V (dual) |
