AD7863ARS-2 - Dual 12-Bit, 1 MSPS, Simultaneous Sampling SAR A/D Converter

The AD7863ARS-2 is a high-performance, dual analog-to-digital converter (ADC) from Analog Devices Inc. Designed for applications that require simultaneous and independent sampling of two channels, this converter is an ideal choice for motor control, data acquisition systems, and digital signal processing.

This precision ADC features two 12-bit SAR (Successive Approximation Register) ADCs that can sample at speeds up to 1 MSPS (Mega Samples Per Second). The simultaneous sampling feature ensures that the signal conversion from analog to digital in both channels is synchronized, which is critical for phase-sensitive applications.

The AD7863ARS-2 operates from a single 5V supply and includes a high-speed 12-bit ADC, on-chip track-and-hold circuitry, and a high-speed serial interface. This product is designed to offer excellent dynamic performance, with a signal-to-noise ratio (SNR) of 73 dB and a total harmonic distortion (THD) of -85 dB.

The device comes in a 28-lead SSOP (Shrink Small Outline Package), making it compact and suitable for space-constrained applications. Its low power consumption is another highlight, requiring only 15 mW at 1 MSPS, which reduces to 10 µW in power-down mode, making it an energy-efficient choice for portable devices.

Key features of the AD7863ARS-2 include:

• Dual 12-bit, 1 MSPS sampling rate
• Simultaneous sampling of two channels
• Single 5V supply operation
• Low power consumption: 15 mW at 1 MSPS, 10 µW in power-down mode
• High-speed serial interface
• SNR of 73 dB and THD of -85 dB
• Compact 28-lead SSOP package

The AD7863ARS-2 is optimized for applications that require high-speed, simultaneous sampling of multiple channels with minimal power usage. It is a robust solution for engineers looking to improve the performance and efficiency of their systems.
