AD8622/AD8624 are low power, high precision rail-to-rail output operational amplifiers with low supply currents, low input offset voltage drift, low noise and wide operating temperature range. They are suitable for portable precision instrumentation, laser diode control loops, strain gage amplifiers, medical instrumentation and thermocouple amplifiers applications.
The AD8622 (dual) and AD8624 (quad) are low‑power precision rail‑to‑rail output operational amplifiers designed for portable instrumentation, laser‑diode control, strain‑gage amplification, medical and thermocouple applications. They feature very low offset voltage, low bias current, and low voltage noise, and operate over an extended industrial temperature range.
