Data Acquisition - Analog to Digital Converters (ADC) are used to convert analog signals into digital signals and allow electronic devices to be controlled and monitored remotely. The AD9057BRSZ-RL60 is a data acquisition system consisting of a 16-bit Analog-to-Digital Converter (ADC). This ADC is designed in a wide variety of application fields, such as automotive, industrial, medical and aerospace.

The AD9057BRSZ-RL60 utilizes a sampling methodology known as sigma-delta conversion with a 1-bit function to reduce noise and interference from the input signal. When an analog signal is introduced into the ADC, it is first passed through an anti-aliasing filter for filtering and attenuation of unwanted signals. The signal then goes through an analog multiplexer, and then a gain-programmable pre-amplifier for amplification and further filtering before reaching the A-to-D converter.

The sigma-delta modulator consists of a comparator, integrator, and digital filter that allow the signal to be sampled and then digitally converted. The first step in the process is the comparator, which compares the amplitude of the input signal to a reference signal known as the quantization level. If the input signal’s amplitude is lower than the quantization level, a respective voltage is outputted to the integrator. If the input signal’s amplitude is higher than the quantization level, the comparator sends a zero voltage output to the integrator. When the signal is integrated, it is digitally filtered and the resulting signal is fed back to the comparator in order to achieve a higher resolution.

The AD9057BRSZ-RL60 also incorporates a reference voltage generator for boost/ dropping the input signals captured by the analog front end. This reference voltage generator also helps in providing a stable and static reference voltage to the ADC. Furthermore, it also contains various digital filters, such as a two-pole Butterworth filter with a cutoff frequency of 154kHz, a sinc filter with a cutoff frequency of 154kHz, and a sample and hold filter for controlling the frequency of noise and crosstalk.

Ultimately, the AD9057BRSZ-RL60 is an excellent choice for high-resolution analog-to-digital conversions. This ADC is designed to provide low distortion and noise without needing an external system to power the module. It is easy to install and maintain while also being cost-effective. As such, the AD9057BRSZ-RL60 is an ideal choice for a variety of different applications and industries.
