AD7780BRZ Analog to Digital Converters (ADCs) are widely used in data acquisition. They are well suited for applications that require high accuracy and low noise, including professional audio, as well as test and measurement. The AD7780BRZ is a 16-bit, single-channel, SAR ADC that offers excellent linearity, low noises and high dynamic range. It has an integrated, wide-range clock and an integrated low-pass filter for improved signal-to-noise ratio.

The AD7780BRZ is designed to measure a wide range of common analog signals, including temperature, pressure and strain. It converts analog signals into digital form with outstanding accuracy of up to 16-bits, making it suitable for use in a variety of precision measurement and control systems. The device features a sophisticated on-chip correction algorithm that allows it to accurately measure even the most demanding signals at low power.

The core of the AD7780BRZ is a Sarlogic-based conversion technique that is capable of providing sampling speeds up to 1MHz. The device uses an on-chip clock oscillator to avoid any variation in A-to-D conversion speed due to environmental or clock signal variations. This ensures reliable and consistent A-to-D conversion performance over a wide range of temperatures and other operating conditions. Additionally, the device supports a variety of input signal sources, including differential and single-ended input signals.

The AD7780BRZ offers an impressive sampling rate of up to 1 MHz, and has a wide-range of adjustable input signal filtering, programmable gain and offset, and programmable converter rate. With a wide range of features, it is well suited for use in high resolution signal measurement applications such as test and measurement, professional audio, and process control.

The underlying operating principles of the AD7780BRZ are based on a successive approximation-based architecture that uses many successive steps to approach the analog signal input level. The device uses an on-chip program logic with a successive approximation aligner (SAR) to convert the analog inputs into 16-bit digital values. It is capable of providing a very high degree of conversion accuracy and signal resolution.

The AD7780BRZ also has an integrated low-pass filter, which reduces noise and helps to achieve higher signal resolution. This filter is designed to work efficiently with the ADC\'s program logic and is adjustable in three stages to allow for optimum performance. This can improve signal-to-noise ratio and reduce artifacts, therefore allowing for a more accurate conversion.

The AD7780BRZ also includes a wide range of digital support features, such as an interrupt service request, output sleep feature, serial data throughput, and more. The device has a programmable offset and gain that allows the user to tailor the device to the specific application needs. Additionally, the device can be configured to work with an external voltage reference or an on-chip internal voltage reference, providing flexibility in applications where an external reference may not be available.

Overall, the AD7780BRZ is a powerful and reliable analog-to-digital conversion solution suitable for a wide range of precision measurement and control applications. With its wide range of features, it provides a cost-effective solution for improving measurement accuracy and system performance. Its SAR-based architecture provides excellent conversion accuracy, low noise, and high dynamic range, making it an ideal choice for high-performance signal measurement.
