Description
AD8275ARMZ-RL is Analog Devices’ precision instrumentation amplifier (INA) used to condition small differential sensor signals. It is well-suited for bridge sensors (strain gauges, load cells), RTDs, thermocouples, and other sensor front-ends where low offset, low drift, and good CMRR are important. Gain is set with an external RG resistor, giving a wide range of amplification suitable for various applications. The ARMZ suffix indicates an 8‑lead MSOP package; RL denotes RoHS-compliant, tape-and-reel packaging for automated assembly. Typical advantages include low input bias current and broad supply-range support for single or dual-supply operation. For exact electrical specs, pinout, and operating conditions, refer to the AD8275 datasheet.
Features
AD8275ARMZ-RL is a precision instrumentation amplifier with flexible gain and bias features. Key features include:
- RG-programmable gain from 1 to 1000 for wide sensor-range conditioning
- REF pin to level-shift the output
- Low input-referred noise and low offset with low drift
- High common-mode rejection ratio (CMRR) over frequency
- Wide supply range; supports single- or dual-supply operation
- Suitable for fast signal conditioning with broad bandwidth (GBW scales with gain)
- Input protection/robustness suitable for interfacing sensors
- 8-lead MSOP package (ARMZ), RoHS-compliant
- Tape-and-reel packaging (RL) for automated assembly
- Industrial temperature range (typical -40°C to +125°C)
