Analog to Digital Converters (ADCs) provide a key function in a variety of consumer electronic systems. Their purpose is to convert analog signals, such as audio or video signals, into digital data that can be analyzed and manipulated by a microprocessor or computer. Nowadays, more and more ADCs are employed in the fields of consumer electronics, healthcare, agriculture, military and communications.
Among all the ADCs in the market, one of the most popular is the AD9643-250EBZ which is a high performance 10-bit Analog to Digital Converter from Analog Devices. The AD9643-250EBZ is a low-power, single-channel A/D converter and features excellent AC and DC performance. The device is specified for a 10-bit accuracy over the temperature range of −40°C to +105°C. With its low power consumption, small package size and excellent performance, the AD9643-250EBZ is ideal for applications such as consumer electronics, automotive, and medical equipment.
The AD9643-250EBZ operates on a single 5 V to 3.3 V supply and is specified with different signal ranges depending on the operating voltage. Its power dissipation is 150 mW at 3.3 V and 120 mW at 1.8 V. It offers a low power standby mode, which allows it to perform conversions while consuming less than 1 µW of power. The device has an on-chip gain stage, which can be used to amplify signals before they are converted. It also has an integrated reference amplifier to provide a wide range of signal reference levels.
The AD9643-250EBZ has several advanced features such as differential, parallel, and serial data I/O, wide signal bandwidth (up to 100 MHz), fast conversion speed (up to 200 Msps), low glitch impulse (Fmax < 15MHz), selectable sample control clock, autocalibration, and an on-chip sample-and-hold (S&H) circuit. The device includes an integrated temperature sensor to compensate for non-linearities related to temperature drifts and provide a stable output. Additionally, the device includes an on-chip low-drift built-in reference amplifier for wide signal range outputs.
The AD9643-250EBZ is designed specifically for high speed, single channel applications, including applications with tight timing constraints such as medical imaging. It is highly versatile and can be used as a standalone ADC or be incorporated into a system via an evaluation board. The evaluation board includes an integrated USB interface to program and control the ADC, as well as a built-in test signal generator, a spectrum analyzer, and a power supply that can be used to power the device. In addition to the evaluation board, the AD9643-250EBZ also comes with a dedicated library of drivers and tools that can be used to ease the development process.
