ADS7951SRGER

Data Acquisition - Analog to Digital Converters (ADC)

Analog to Digital Converters (ADC) are devices that convert analog signals into digital signals. One such device is the ADS7951SRGER, which is a low power precision ADC from Texas Instruments. This device is ideal for use in battery-powered systems with ultra-low power consumption for remote sensing applications. In this article, the application field and working principle of the ADS7951SRGER will be discussed.

Application Field

The ADS7951SRGER is an ideal device for use in remote sensing applications. This is because it has a dynamic range of 0.5 µV to 4.095 V and is capable of converting analog signals into 12-bit resolution digital signals with a conversion time of 22 µs. Additionally, it is capable of operating at temperatures ranging from -40°C to +85°C, making it well-suited for use in portable or outdoor battery-powered systems. Furthermore, it has the highest resolution in its product category and is the lowest power combined with the highest total accuracy. This makes it an excellent choice for precision sensing applications.

Working Principle

The ADS7951SRGER is based on a Sigma-Delta (Σ∆) analog to digital converter. This type of ADC is designed for low-power, high-resolution applications and works by oversampling an input signal to obtain a high-resolution output. This is done by a modulator which converts the analog input into a multi-bit digital signal. In the case of the ADS7951SRGER, this is a 12-bit digital signal. The modulator is then connected to a digital filter, where the digital output is filtered to remove any noise or distortion. Finally, the output is sent to the digital-to-analog converter, where the analog signal is converted back into a digital signal.

In addition to this, the ADS7951SRGER also features an on-chip temperature sensor and a low-power standby mode, making it well-suited for ultra-low power consumption applications. Additionally, it has on board calibration and trim features which allow for fine tuning of the device. This ensures that the device is able to operate with maximum performance.

Conclusion

In conclusion, the ADS7951SRGER is an excellent choice for use in remote sensing applications because of its low-power consumption, high-resolution output and wide operating temperature range. Additionally, its on-chip temperature sensor, low-power standby mode and on board calibration and trim features make it an ideal choice for precision sensing applications. With these features, the ADS7951SRGER is sure to be a valuable tool in a variety of applications.
