The AD626 is a low-cost, single-supply differential amplifier with selectable gains, true single-supply operation, and a wide input voltage range.
The AD626 is a low‑cost, single‑supply differential amplifier with selectable gains of 10 and 100. It offers true single‑supply operation, a wide output voltage swing, low input offset voltage, and excellent common‑mode rejection, making it suitable for current‑sensing, pressure‑transducer interfaces, and bridge applications.
The document includes detailed electrical specifications, absolute maximum ratings, ordering information for the AD626A and AD626B variants, typical performance graphs, and mechanical outline dimensions for both 8‑lead PDIP and SOIC packages.
| Input Offset Voltage | 1.9 – 2.5 mV (typical 2.5 mV) |
|---|---|
| Positive Output Voltage Swing (Gain = 10) | 4.7 V – 4.90 V |
| Quiescent Current (Gain = 10) | 0.16 mA typ (0.20 mA max) |
The AD626 can run from a single supply of +2.4 V to +10 V, or from dual supplies of +1.2 V to +6 V.
The input offset voltage is specified as 1.9 – 2.5 mV, with a typical value of 2.5 mV.
