The AD8676 is a precision operational amplifier that features 2.8 nV/√Hz low voltage noise, 120 dB high gain, 10 MHz wide bandwidth, and 36 V maximum operating voltage.
The AD8676 is a dual, rail‑to‑rail output operational amplifier offering ultra‑low voltage noise (2.8 nV/√Hz at 1 kHz) and very high gain (120 dB). It operates from +5 V to +18 V and is suited for precision instrumentation, PLL filters, laser‑diode control loops, strain‑gage amplifiers, medical instrumentation, and thermocouple amplifiers.
The device is available in lead‑free 8‑lead SOIC and MSOP packages, supports an extended industrial temperature range (‑40 °C to +125 °C), and provides typical supply current of 3.2 mA, output swing up to ±4.9 V, and a slew rate of 25 V/µs. Detailed electrical specifications, pin configurations, and typical performance graphs are included.
