The AD7864ASZ-1 is a high-performance, 12-bit, 4-channel simultaneous sampling analog-to-digital converter (ADC) from Analog Devices Inc., designed to meet the rigorous demands of signal processing applications that require multiple ADCs to capture analog signals at the same time.

Key Features

• Resolution: 12-bit ADC offers fine granularity for a wide range of applications.
• Simultaneous Sampling: Four fully differential analog inputs sampled simultaneously to preserve the relative timing information of the signals.
• High Throughput: With a 125 kSPS per channel sampling rate, it provides high-speed data acquisition, making it ideal for applications that require rapid and accurate data capture.
• Input Voltage Range: ±10 V input range with the AD7864-10, ±5 V with the AD7864-5, and ±2.5 V with the AD7864-2.5.
• Low Power Consumption: Operates with a single 5 V supply and features a sleep mode to reduce power consumption during idle periods.
• Interface: Easy interface to all microprocessors, compatible with QSPI™, SPI™, MICROWIRE™, and DSP interface standards.

Applications

The AD7864ASZ-1 is particularly well-suited for applications where multiple analog signals need to be digitized simultaneously, such as:

• Phase-locked loops (PLLs)
• Motor control feedback systems
• Multi-axis positioning systems
• Data acquisition systems
• Vibration analysis

Technical Specifications

The AD7864ASZ-1 by Analog Devices Inc. is an exceptional choice for engineers looking for an ADC that combines high-speed, precision, and the ability to handle multiple signal inputs without compromise on performance.
