The AD8251 is a 10-bit digitally programmable gain instrumentation amplifier with GΩ input impedance, low output noise, high CMRR and high slew rate.
The AD8251 is a programmable‑gain instrumentation amplifier offered in a 10‑lead MSOP package. It supports selectable gains of 1, 2, 4 or 8, a wide supply range of +5 V to +15 V, and delivers high performance with low noise, low distortion and fast settling time.
The document includes detailed specifications, absolute maximum ratings, pin configuration, timing diagrams, typical performance curves and ordering information, helping designers integrate the device into data‑acquisition, biomedical and test‑and‑measurement systems.
| Supply Voltage Range | +5 V to +15 V |
|---|---|
| Quiescent Current (typical) | 4.1 mA |
| Slew Rate (G=1) | 20 V/µs |
The AD8251 provides programmable gains of 1, 2, 4, and 8.
The device operates from +5 V to +15 V (and –5 V to –15 V for dual‑supply operation).
Typical quiescent current is 4.1 mA.
The AD8251 is available in a 10‑lead MSOP (Mini Small Outline Package).
