The AD627 is a micropower, single- and dual-supply, rail-to-rail instrumentation amplifier from Analog Devices
The AD627 is a micropower instrumentation amplifier that operates from single‑ or dual‑supply voltages (+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) up to 1000.
It offers low input offset voltage, low bias current, high CMRR, and low noise, making it suitable for battery‑powered, medical, industrial, and data‑acquisition applications.
| Gain range | 5 to 1000 |
|---|---|
| Supply voltage range | +2.2 V to +18 V |
| Quiescent current | 85 pA (typical) |
| Bandwidth (G=+5, single supply) | 80 kHz |
| Input offset voltage (AD627B, dual supply) | 125 pV (typical) |
| CMRR (G=+5) | 77 dB (typical) |
The AD627 can be set for a gain from 5 (no external resistor) up to 1000 with a single external resistor.
It operates from a single‑supply voltage of +2.2 V up to +18 V, or dual supplies of +2.2 V to +18 V each.
The device draws a typical quiescent current of 85 pA.
At a gain of +5, the AD627 has a typical bandwidth of 80 kHz.
