Key Featrues
High-Speed 1-MSPS Sampling Rate: The ADS79xx family supports a 1-MSPS (Mega Samples Per Second) sampling rate, enabling fast and accurate data acquisition. This feature is particularly beneficial for applications requiring real-time signal processing, such as industrial automation and medical diagnostics, where high-speed data capture is critical for performance and efficiency.
Wide Analog Supply Range (2.7 V to 5.25 V): The device operates over a broad analog supply range, making it versatile for various power supply configurations. This flexibility allows for seamless integration into both low-power and high-voltage systems, enhancing its applicability in battery-powered devices and systems with isolated power supplies.
Programmable Alarm Thresholds per Channel: Each channel supports two programmable alarm thresholds, enabling precise monitoring of input signals. This feature is ideal for safety-critical applications, such as environmental monitoring or fault detection, where immediate alerts for out-of-range conditions are necessary to ensure system reliability.
Low Power Consumption (14.5 mW at 1 MSPS): With typical power dissipation of 14.5 mW at 1 MSPS, the ADS79xx family is highly energy-efficient. This low power consumption makes it suitable for portable and battery-operated devices, extending battery life and reducing operational costs in power-sensitive applications.
Flexible Input Range Selection (0 V to VREF or 0 V to 2×VREF): The device offers two software-selectable input ranges, allowing users to optimize the ADC's dynamic range for specific signal levels. This feature enhances measurement accuracy and flexibility, making it adaptable to diverse use cases, from low-voltage sensor readings to higher-voltage industrial signals.
