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.

Key Features :

• High CMRR: Ensures stable and accurate signal conditioning with a Common Mode Rejection Ratio of 100 dB (G = 10).
• Adjustable Gain: Gain can be set from 1 to 1000 using a single external resistor, allowing flexibility for diverse applications.
• Wide Operating Range: Compatible with dual supply voltages from 2.3 V to 18 V, making it versatile for various systems.
• Low Power Consumption: Draws only 1.3 mA, ideal for battery-powered and portable equipment.
• Low Input Offset Voltage: Excellent accuracy with a low offset of 50 uV (max) and low drift of 0.6 uV/°C.
• Low Noise Performance: Low input noise of 9 nV/√Hz at 1 kHz, suitable for amplifying low-level signals with minimal interference.
