XL620 – Instrumentation Amplifier – Xinluda

The Xinluda XL620 is a single-channel, high-precision instrumentation amplifier in an SOP-8 package, featuring low input offset voltage and a single-resistor programmable gain from 1 to 10,000 for sensor and data-acquisition front ends.

The Xinluda XL620 is a single-channel, high-precision instrumentation amplifier designed for low-level signal conditioning in measurement and data-acquisition systems. Housed in a compact SOP-8 package, the XL620 combines low input offset voltage, low offset drift, and a wide supply range to deliver accurate amplification of small differential signals in the presence of common-mode noise. Its gain is set with a single external resistor over a broad range of 1 to 10,000, simplifying board design while preserving precision.
