AD8274ARZ-R7

AD8274ARZ-R7 is an Analog Devices instrumentation amplifier. It is designed to amplify small differential signals from sensors while rejecting large common-mode voltages, giving clean, precise measurements.
Key points:
- High common‑mode rejection, low input offset and bias currents, and low noise for accurate sensing.
- Gain is set externally (RG) to cover multiple ranges; suitable for fixed or adjustable gain applications.
- Wide supply options (single or dual supplies) and versatile input/output headroom for various sensors.
- Intended uses include bridge sensors (load cells, strain gauges), RTDs/thermocouples, current sensing, and biomedical signals.
Package variant ARZ-R7 denotes a specific package/temperature/traceability option; check the datasheet for exact pinout, rail limits, RG gain options, and electrical characteristics.
How to use briefly: connect the sensor differentially to +IN and -IN, choose RG to set the desired gain, reference the output with REF (to mid-supply or ground), and supply the IC. This device provides high-precision amplification for DC to low-frequency signals.

Here are concise features of AD8274ARZ-R7:
- Precision instrumentation amplifier with integrated gain setting (three-op-amp internal architecture)
- External RG sets gain over a wide range
- High input impedance with excellent common-mode rejection (CMRR)
- Low input offset voltage, low offset drift, and low input bias current
