Analog-to-Digital converters (ADCs) play a critical role in data acquisition and convert continuous physical data from a dynamic range of analog signals to digital formats. The AD9235BRUZRL7-20 is an eight-channel, 1.7-GS/s, 20-bit successive approximation register (SAR) ADC and is designed to be used in a variety of data acquisition, industrial and military applications. It is an ideal choice for applications that require excellent dynamic performance, wide input bandwidth, low power consumption and flexibility in a small package.

The AD9235BRUZRL7-20 has the capability of sampling eight differential analog inputs simultaneously. Additionally, it has the capability of single-channel and dual-channel (interleaved) sample-and-hold inputs. This allows for a wide dynamic range from -67 dBFS to +92 dBFS, a sample-and-hold settling time of 200 ns, and a signal-to-noise ratio (SNR) of 95 dBFS. It also has a differential nonlinearity (DNL) of ±2.0 LSB and an integral nonlinearity (INL) of ±1.0 LSB.

The AD9235BRUZRL7-20 has a versatile architecture that can be configured for multiple data format conversion, including 8-bit parallelism, 8-bit and 10-bit serial conversion, and 10-bit dual-channel conversion. The clock input can be set to up to 1.7 GS/s and the output data rate can be configured to up to 1.28 GS/s. The converter also features an on-board Voltage Reference and a three-level threshold detector. Additionally, it can be programmed to have up to three different gain settings.

The AD9235BRUZRL7-20 is designed to be used in a variety of data acquisition, industrial, and military applications. It provides high performance, low power consumption, and excellent signal-to-noise ratio in a small form factor, which makes it an ideal choice for applications that require high resolution and dynamic range. It can be used for a variety of applications, including data logging and monitoring, instrumentation and control systems, audio processing, robotics, avionics, medical imaging, automotive ADAS, and wireless communications.

The working principle of the AD9235BRUZRL7-20 is based on SAR ADC technology. The SAR ADC uses a successive approximation register to convert an analog signal into a digital signal. The input voltage is applied to a sample-and-hold circuit, which is then compared to the reference voltage. The comparator output is then used to update the successive approximation register, which is a special type of binary counter. The process of comparison and register update is repeated until the analog signal is accurately converted into a digital value.

The AD9235BRUZRL7-20 is an ideal choice for applications that require high resolution and dynamic range. Its versatile architecture makes it highly configurable and its fast conversion rate makes it an attractive choice for a variety of data acquisition applications.
