The AD7709BRU is an integrated circuit (IC) component that belongs to the AD7709 family of analog front-end (AFE) devices manufactured by Analog Devices. It is specifically designed for precise data acquisition and conversion of analog signals to digital form. The AD7709BRU offers high-resolution conversion, low-power operation, and a versatile interface, making it suitable for a wide range of applications.
Key Features:
1. Two-Channel Sigma-Delta ADC: The AD7709BRU features two independent channels of sigma-delta analog-to-digital conversion. This allows simultaneous conversion of two analog input signals, reducing the need for multiple ADCs.
2. High-Resolution Conversion: The IC provides a high resolution of up to 16 bits, enabling precise and accurate conversion of analog signals. The resolution can be configured to lower values to increase the conversion speed.
3. Low-Noise and High-Accuracy Operation: The AD7709BRU incorporates a low-noise programmable gain amplifier (PGA), allowing the IC to amplify small analog signals while maintaining high accuracy. It also features an on-chip self-calibration feature that enhances accuracy and minimizes external calibration requirements.
4. Programmable Filter and Data Rates: The IC offers a programmable digital filter with two filter options, fast settling or low noise, which can be configured based on the requirements of the application
