AD627 is a micropower, single/dual supply, rail-to-rail instrumentation amplifier produced by Analog Devices.
The AD627 is a micropower instrumentation amplifier that operates from single or dual supplies (+2.2 V to +18 V) and provides rail‑to‑rail output swing. Gain is set with a single external resistor, ranging from 5 (no resistor) to 1000.
Its low quiescent current (85 µA max) and low offset voltage make it suitable for battery‑powered, medical, industrial and data‑acquisition applications.
| Supply Voltage Range | +2.2 V to +18 V |
|---|---|
| Quiescent Current | 85 µA max |
| Gain Range | 5 to 1000 |
| Bandwidth (Gain = +5) | 80 kHz |
| Input Offset Voltage (AD627B) | 125 pV max |
| Input Noise | 38 nV/√Hz at 1 kHz (G=+100) |
It operates from +2.2 V up to +18 V on single or dual supplies.
Gain is set with a single external resistor; without a resistor the gain is 5, and with a resistor it can be programmed up to 1000.
The device draws a maximum of 85 µA of supply current.
The bandwidth is 80 kHz when the gain is set to +5.
