Data Acquisition - Analog to Digital Converters (ADC) are an important component of instrumentation, communication and control systems. The ADS7280IRSAR is a high-performance, low noise, low power CMOS Analog to Digital Converter (ADC). It is a monolithic, single-chip device, designed for high-speed conversion of analog signals into digital signals in industrial, automotive and communications applications. This article will provide an overview of the ADS7280IRSAR application field and its working principle.

The ADS7280IRSAR is a single-supply, low-cost, low-power Analog to Digital Converter (ADC). It features 12-bit resolution and a maximum conversion rate of 2Msps. The ADC can handle analog input ranges of 2.5V and 4V with a single-ended or differential analog input. The low power consumption of 56mW makes it ideal for battery powered applications. The device has a ±1LSB DNL and a ±2LSB INL to provide the necessary accuracy. It also features a power-down mode, allowing the user to control the system power consumption. Additionally, the ADC has an on-board temperature sensor, allowing the user to measure the device’s operating temperature.

The ADS7280IRSAR is ideal for use in industrial, automotive, and communications applications. It can be used in industrial process control systems, motor control systems, automotive engine control systems and communications systems.
