AD7863AR-10 Dual 12-Bit, 1 MSPS, Simultaneous Sampling A/D Converter

The AD7863AR-10 is a high-performance analog-to-digital converter (ADC) manufactured by Analog Devices Inc. This precision ADC is designed for applications requiring simultaneous and independent sampling of multiple channels, making it an ideal choice for data acquisition systems, industrial control, medical imaging, and multichannel data logging.

At the heart of the AD7863AR-10 lies a pair of 12-bit, 1 MSPS sampling ADCs, which allow for simultaneous sampling of two analog signals. This feature ensures that the phase information between the two channels is preserved, which is critical for applications such as phase-sensitive detection in motor control and power quality monitoring.

The device operates from a single 5 V power supply and features a high-speed parallel interface for quick data transfer. The input voltage range is ±10 V, providing a wide dynamic range for various signal types. The AD7863AR-10 also boasts a low power consumption of just 90 mW at full speed, which drops to 30 μW in power-down mode, making it suitable for power-sensitive applications.

Key features of the AD7863AR-10 include:

• Dual 12-bit SAR ADCs with simultaneous sampling
• 1 MSPS conversion rate per channel
• Single 5 V power supply operation
• Wide input voltage range of ±10 V
• High-speed parallel interface
• Low power operation with power-down mode
• Integrated track/hold function
• Overvoltage protection on the analog inputs

The device is available in a 28-lead TSSOP (Thin Shrink Small Outline Package) and is specified for operation over the industrial temperature range of -40°C to +85°C. The robust design and high reliability of the AD7863AR-10 make it an excellent choice for demanding environments where accurate and reliable data conversion is critical.

Overall, the AD7863AR-10 from Analog Devices Inc. is a versatile and efficient solution for simultaneous sampling ADC applications, offering high-speed performance, precision, and low power consumption in a compact package.
