Data Acquisition and the Analog-to-Digital Converters (ADC) are very important in many technological and industrial processes. For this reason, the selection of a suitable device to convert analog signals into digital ones is critical in order to get the accurate data needed for processes. In this regard, the AD9446BSVZ-100 Converter is an algorithmic ADC with a high acquisition rate and wide analog input range, recommended as an ideal solution for data acquisition.

The AD9446BSVZ-100 is an 16-bit, low power, CMOS device that can achieve a resolution up to 1 mV and a sampling rate up to 100 M-sps. It provides a versatile input parameters including full-scale range of ± 25mV, a reference voltage range of ± 1V, and an input impedance range of 0.1 say a twoand a half decade. This device is also extremely versatile in terms of outputs as it can provide both a digital 2-bit data stream and an analog voltage output. The device is controlled through a single, simple SPI control port.

Mainly, the AD9446BSVZ-100 working principle consists on its digital core consisting of a Sigma-Delta Modulator and low-pass loop filter. This modulator is an oversampling modulator which uses one or more bits of digital information for each bit of the analog signal output. The high-speed modulator digital output is filtered to reduce the noise and distortion of the low-frequency components until the signal fits the desired bandwidth. The output is then decimated to a lower sampling rate, finally providing the digitized signal.

The potential applications of the AD9446BSVZ-100 are vast, due to its high precision performance, low power consumption, small form factor and wide analog signal range. This device can be used in data bandwidth and low noise signal processing applications such as test & measurement equipment, medical imaging systems, automotive and industrial control systems, etc. Moreover, this device is also suitable for applications such as ultrasonic flow meters, OTDR (Optical Time Domain Reflectometry), Base-band signal reception and modulation, Magnetic resonance imaging, Magnetoencephalogram systems, among others.

To sum up, the AD9446BSVZ-100 is an algorithmic ADC with an excellent signal conversion performance, and wide analog input range, making it ideal for a variety of analog to digital signal conversions. An array of potential applications makes it the ideal device for data acquisition, making it a reliable source of digital information.
