Overview
The AD8228BRMZ-RL, produced by Analog Devices Inc., is a high-performance instrumentation amplifier known for its very high gain accuracy and low gain drift. This amplifier features internal and laser-trimmed gain setting resistors, which enhance its gain accuracy and stability. It operates on both single and dual power supplies, with a wide power supply range of ±2.3 V to ±18 V, making it suitable for applications requiring high common-mode input voltages. The AD8228BRMZ-RL is available in an 8-lead MSOP package and is specified over the industrial temperature range of −40°C to +85°C, with operational capabilities extending up to +125°C.
