AD 622 – Low-Cost Instrumentation Amplifier

The AD622 is a low-cost, moderately accurate instrumentation amplifier that simplifies precision signal amplification. Requiring only one external resistor to set gains between 2 and 1000, or no resistor for unity gain, it offers superior linearity and common-mode rejection, making it ideal for applications such as transducer interfacing, thermocouple amplification, and industrial process controls.

Key Features:

• Easy Gain Configuration: Gain adjustable from 2 to 1000 with a single external resistor; unity gain achievable without external components.
• Wide Power Supply Range: Operates effectively from ±2.6 V to ±15 V, accommodating various system requirements.
• Low Power Consumption: Consumes a maximum of 1.5 mA supply current, suitable for power-sensitive applications.
• Excellent DC Performance: Features 0.15% gain accuracy at G = 1, 125 µV max input offset voltage, and 1.0 µV/°C max input offset drift.
• Low Noise: Offers 12 nV/√Hz input voltage noise at 1 kHz and 0.60 µV p-p noise from 0.1 Hz to 10 Hz at G = 10.
• Compact Packaging: Available in 8-lead PDIP and SOIC_N packages for easy integration into various designs.

Package Includes:

• 1 x AD622 – Low-Cost Instrumentation Amplifier
