The AD7862AN-10 is a high-performance, low-power, serial analog-to-digital converter (ADC) from Analog Devices. This device is designed for applications that requires accurate and fast conversion of analog signals to digital signals, such as portable applications where low power consumption and a small form factor are important considerations. It is characterized with a 10-bit resolution, a sampling rate of up to 100 Hz, and a k 75 dB signal-to-noise ratio (SNR). It features an integrated 10-channel, 16-bit successive approximation register (SAR) converter, allowing for digital processing of high- band width applications.

The AD7862AN-10 offers differential gain and offset errors of 0.005%. It also features temperature stability up to ±1°C. The converter utilizes a successive approximation register architecture, allowing it to convert analog input signals into digital codes with high resolution and low power consumption. It features an active digital filter to reduce the noise level, and a unity-gain servo loop for circuit stabilization. The converter is also equipped with an auto-calibrating programmable gain amplifier (PGA), allowing the user to adjust output gains digitally.

The AD7862AN-10 is designed for applications that require accurate and reliable analog-to-digital conversions. It is particularly suitable for use in medical imaging systems, CCD/CMOS cameras, industrial process control systems, and motion detection systems. Its integrated 10-channel input port allows the user to connect to a variety of analog sensing devices, such as thermocouples, strain gauges, load cells, and pressure sensors.

The AD7862AN-10 utilizes a cyclic code architecture, which utilizes fewer bits than conventional architectures with the same resolution, resulting in reduced power consumption and increased accuracy. The device is designed to operate from a single 5 V power supply and has internal reference voltage options. The device is also equipped with a sleep mode, allowing the user to go into a low-power consumption mode when the device is not in use, thus extending the system battery life.

The AD7862AN-10 is a low-power, high-accuracy data acquisition system intended for applications that require a simple, reliable and accurate solution for analog-to-digital data acquisition. It features a wide input range, temperature stability, selectable gain and offset trimmers, 10-bit resolution and fast conversion rates. The use of differential inputs allows the user to reduce the external noise imposed on the system. With a 5 V power supply, the device consumes only 90 mW of power, making it ideal for use in small and portable systems.
