The AD9643-170EBZ evaluation board (EVAL-ADXL375Z) is an analog-to-digital converter (ADC) from Analog Devices, Inc. (ADI) designed to provide high-accuracy data acquisition for various applications, including thermal management, medical, automotive, avionics, and industrial control. The AD9643-170EBZ is based on ADI\'s AD9643 16-bit, 155 Msps ADC, and features an on-board reference, digital power supplies, digital-control logic, and various analog- and digital-programming capabilities.

The AD9643-170EBZ’s 16-bit resolution offers a smooth analog-signal conversion performance of up to 155 MSPS (mega-samples per second), which allows for faster and more precise measurements and data processing than comparative 8-bit and 10-bit converters. The ADC incorporates a built-in low-noise amplifier as well as a variable-gain amplifier, making it ideal for applications requiring either low-noise or wide dynamic range amplification or conversion.

The AD9643-170EBZ has four differential inputs with a maximum sample rate of 155 MSPS, allowing for increased signal-processing speeds and higher-resolution data acquisition. The board includes a dual-channel 16-bit parallel output port, an 8-bit SPI port, or a single 10-bit serial port for programming parameters. The parallel port is compatible with a variety of off-the-shelf field-programmable gate arrays (FPGAs) for increased flexibility.

To meet power requirements and ensure stable operation, the AD9643-170EBZ offers the Industry-standard 3.3V LVPECL (low-voltage-signal-level-packet-electrical-coupling). The board includes a regulator and DC/DC converter to provide dependable power when used in mobile and/or power-sensitive applications. The sophisticated power-management system supplied with the AD9643-170EBZ includes a comprehensive set of control logic and peripheral circuitry.

The AD9643-170EBZ evaluation board also features a dual-channel analog reference voltage generator, which allows for analog-system design. This generator provides both 0-10V and ±5V voltage references for adjustable gain or offset settings. Moreover, the reference generator includes a temperature sensor to maintain accurate analog outputs. Furthermore, the board includes an overrun and underrun indicator and status outputs to provide the user with real-time feedback.

The AD9643-170EBZ evaluation board utilizes an on-board controller, which can be programmed to various parameters for reliable operation. The on-board logic includes a reset input, a voltage regulator, several control inputs, and 5V and 3V power inputs. The D/D converter can be switched between 5V or 3.3V as required by the application. Additionally, the on-board logic can be easily programmed via a digital control port or an on-board JTAG port, allowing for a variety of customizations.

The AD9643-170EBZ evaluation board is designed to provide a low-noise, high-accuracy analog-to-digital conversion solution. It can acquire data at up to 155 MSPS and provide excellent thermal management and power efficiency. The on-board dual-channel reference generator, along with a variety of programming options, make the board ideal for applications requiring reliable data acquisition. Additionally, the board includes sophisticated power-management circuitry and support for a wide variety of off-the-shelf FPGAs, making it an excellent value for all types of applications.
