The AD7980BRMZ is a precision, high-speed, 18-bit low power simultaneous sampling analog to digital converter (ADC). This ADC was designed with a high-precision differential track-and-hold amplifier and an 18-bit Σ-Δ modulator, making it suitable for a wide range of data acquisition applications.

The AD7980BRMZ is ideal for use in biomedical and industrial instrumentation applications that require precision, high-speed and low power consumption. It features simultaneous sampling of two input signals to ensure accurate representations of the data of both signals. The device has a sample rate of up to 500 ksps (kilosamples per second). The low power consumption of the ADC makes it ideal for battery powered instruments. The Σ-Δ modulator used in the device provides excellent signal-to-noise ratio and an Extended-range resolution of 18 bits.

The AD7980BRMZ is a differential input device, which means it measures the voltage difference between two input pins rather than the absolute voltage of just one. This allows it to capture the differences between signals riding on different potentials. The differential track-and-hold (DTH) amplifiers allow the data acquisition system to acquire accurate data with signals that have widely varying periods, including those with long intervals between cycles.

The ADC uses a dual conversion method, in which it first measures a signal and then determines the difference between successive samples. This allows for quick and accurate conversion of the data. The ADC features six analog input pins, two for each channel, and two digital output pins for each channel. The digital outputs can be configured to be either unipolar (0-18V) or bipolar (−18 to + 18V).

The AD7980BRMZ features an integrated temperature sensor that can measure its own temperature for temperature compensation. The device has a power switch to minimize power consumption when it is not in use. The low-power operation, in combination with the high-speed capabilities of the device, make it suitable for a wide range of data acquisition applications, including medical imaging, data logging, sensor monitoring and control, and industrial automation.

Overall, the AD7980BRMZ offers excellent performance in its category with its high-precision, high-speed, and low-power characteristics. It is the perfect choice for applications in industries where accurate data acquisition and low-power operation are of the utmost importance.
