The AD621ARZ is an integrated circuit (IC) component designed for instrumentation and amplification purposes. Developed by Analog Devices, this device provides accurate amplification for applications requiring low noise and precision.
One of the key features of the AD621ARZ is its high common-mode voltage range. This range extends from -Vs to +Vs, allowing for flexibility in handling input signal levels in relation to the power supply voltage. The input voltage range can stretch from -Vs+1.5V to +Vs-1.5V, further enhancing the versatility of this IC.
Another notable feature is its low offset voltage, which is typically less than 75 microvolts. This low offset voltage ensures minimal error in signal amplification, enabling precise measurement and control applications. Additionally, the AD621ARZ offers a high open-loop gain, typically above 120 dB, providing further amplification for accurate signal reproduction.
To reduce noise interference, this IC incorporates a low input bias current, as low as 25 nA. This enables high input impedance, minimizing the impact of loading effects on the input signal. Moreover, the AD621ARZ boasts a wide bandwidth of up to 120 kHz, ensuring accurate amplification even for high-frequency signals.
The AD621ARZ operates on a single power supply ranging from 2.3V to 18V, making it suitable for various applications
