AD622, Instrumentation Amplifier,DIP-8, 800kHz Bandwidth, 66dB CMRR

The AD622 is a low-cost, high-performance instrumentation amplifier, ideal for precision signal processing in applications requiring low noise, high gain accuracy, and wide common-mode input voltage range. This amplifier is designed to operate with only a single external resistor, allowing for easy gain adjustment from 1 to 1000. The AD622 provides an excellent CMRR (Common-Mode Rejection Ratio) of up to 66 dB, ensuring superior noise rejection in differential measurements.

Its compact DIP-8 package and low power consumption make it well-suited for portable and low-power applications. With a 800 kHz bandwidth and low offset voltage, this amplifier is perfect for thermocouple amplifiers, bridge amplifiers, medical instrumentation, and data acquisition systems.

Key Features :

• Low-Cost Solution: Cost-effective design with minimal external components required.
• High Gain Accuracy: Configurable gain (G = 1 to 1000) with external resistor; G = 10, 100, or 1000 with no resistor.
• High Common-Mode Rejection: 66 dB (min) at G = 1, maintaining signal integrity in noisy environments.
• Wide Supply Range: Operates from 2.6 V to 18 V, providing flexibility across varied applications.
• Low Power Consumption: Consumes a maximum supply current of only 1.5 mA, ideal for battery-powered systems.
• Robust Temperature Stability: Reliable operation with a temperature range of -40°C to +85°C.
