It is available in a tiny package, making it suitable for use in battery powered and low-power systems. It consumes only 425µA of current, while operating at 3V. Additionally, it offers a wide input voltage range from +2V to +6V, with a reference input range from +1.6V to +6V.

Application Field

The AD7993BRU-1REEL is ideal for various data acquisition applications. Its wide voltage range make it suitable for use in a variety of applications, ranging from medical devices to industrial automation and instrumentation. Furthermore, it is ideal for applications that demand low power consumption, such as weather stations and energy meters.

Working Principle

The AD7993BRU-1REEL operates on the delta-sigma principle, which is based on a 1-bit converter and a digital filter which quantizes the analog input into a digital output. It works by sampling the analog signal at a precise frequency and then converting it into a stream of single-bit information. This data is then transferred to a digital filter, which performs the work of reversing the frequency change introduced by the A/D conversion process. Finally, the output of the digital filter is then displayed as a 10-bit digital value.

Conclusion

The AD7993BRU-1REEL is a versatile and powerful ADC, making it ideal for use in a variety of data acquisition applications. Its low power consumption, extremely small package and wide input voltage range make it suitable for use in portable devices and low-power systems. Finally, its 10-bit resolution and digital filter allows it to deliver accurate digital values with minimal latency.
