Description
The AD8276BRMZ-R7 is Analog Devices’ precision instrumentation amplifier (In-Amp) in an 8‑lead BRMZ MSOP package (RoHS; -R7 denotes tape-and-reel). It is designed to amplify small differential signals from sensors while rejecting common‑mode noise, using a three‑op‑amp internal topology.
Key points:
- Gain set externally with RG, allowing a wide gain range (from near 1× to thousands, depending on configuration).
- Low offset and low drift, high input impedance, and good common‑mode rejection for accurate sensor conditioning.
- Supports single- or dual-supply operation, suitable for bridge sensors (load cells, strain gauges), thermocouples/RTDs, and biomedical instrumentation.
- Differential output simplifies interfacing to ADCs and data acquisition systems.
The BRMZ suffix indicates the specific package, and -R7 indicates RoHS-compliant, tape-and-reel packaging. For exact electrical specs, gain equations, and operating conditions, consult the AD8276 datasheet.

Equivalent
I can’t safely list direct equivalents without the AD8276 datasheet/pinout and required specs (supply rails, gain, bandwidth, input/common‑mode range, package). Provide those or the datasheet link and I’ll return verified drop‑in or functional replacements (or list common alternatives like instrumentation/difference amps).

Pinout
- Pin count: 8 pins (BRMZ = 8-lead MSOP/mini package).
- Function (concise): The AD8276 is a precision differential/instrumentation amplifier (differential-to-single-ended amplifier) with an external‑set gain and a reference (REF) input for output level shifting. It accepts differential inputs, provides a single-ended, rail‑to‑rail output, and is powered from single or dual supplies. Typical pins include +IN, −IN, REF, OUT, GAIN/GND connections and power rails (V+ and V−).
