AD620AN ,Instrumentation Amplifier - High Accuracy, Low Power, DIP-8 Package

The AD620AN is a high-performance instrumentation amplifier from Analog Devices, offering exceptional accuracy and low power consumption. Designed for applications that require precise measurement and signal conditioning, this amplifier operates within a wide supply voltage range from ±2.3 V to ±18 V and provides a high Common Mode Rejection Ratio (CMRR) of 100 dB at a gain of 10, making it ideal for low-level signal amplification. With a low input bias current of 1 nA and adjustable gain via an external resistor, the AD620AN is versatile and adaptable for various applications including medical instrumentation, ECG and EEG measurements, data acquisition systems, and strain gauge signal conditioning.

This amplifier features excellent DC specifications with a low offset voltage of 50 µV (max) and low offset drift of 0.6 µV/°C. Its robust construction in an 8-pin DIP package makes it suitable for integration into designs with compact space requirements.
