The ADS7950SRGER is a dual, low-power, 16-bit analog-to-digital converter (ADC) designed to convert differential, single-ended and common-mode analog signals into digital words. It is targeted at high-accuracy, low-power, low-cost, low-latency applications such as medical imaging, machine vision, instrumentation and communications. This article will cover the application field and working principle of the ADS7950SRGER.

Application Field:

The ADS7950SRGER is ideal for applications where high-accuracy and low-power are paramount. The device features two independent ADC channels, each featuring a wide supply voltage range, low power consumption and low-noise analog signal conditioning. It is equipped with a 16-bit resolution, providing high-accuracy signal conversion. Additionally, the device is configured for differential, single-ended and common-mode signal input. This makes the ADS7950SRGER suitable for medical imaging, machine vision, instrumentation and communications applications.

Working Principle:

The ADS7950SRGER employs a dual-channel delta-sigma analog-to-digital converter to convert differential, single-ended and common-mode analog signals into digital words. The device has two channels, each with its own analog signal conditioning circuits and conversion circuits. Additionally, each channel has a selectable input range of 0 to 5V and a ±2.5V. The single-ended input mode allows for a single input to be converted, while the differential and common-mode modes allow for two inputs to be converted simultaneously.

The device uses a low-noise, low-power delta-sigma ADC architecture, which uses a sigma-delta modulator to generate a digital output. This output is then comparator based and converted into a digital word representing the input information. The device features a 16-bit resolution, allowing it to accurately represent the analog input. Additionally, the device can operate over a wide supply voltage range.

Conclusion

The ADS7950SRGER is an ideal solution for applications requiring high-accuracy and low-power. It features a dual-channel delta-sigma ADC, which allows it to accurately convert analog signals into digital words. Additionally, the device is configured for differential, single-ended and common-mode signals inputs. This makes it suitable for medical imaging, machine vision, instrumentation and communications applications.
