The AD7862ARS-2REEL is an integrated circuit (IC) component that belongs to the AD7862 family, designed and manufactured by Analog Devices Inc. It is a complete dual-channel, 12-bit analog-to-digital converter (ADC) that includes two successive approximation register (SAR) ADCs, an internal voltage reference, and a sequencer for channel scanning.
One of the key features of the AD7862ARS-2REEL is its high level of precision in converting analog signals to digital values. With a resolution of 12 bits, it can accurately convert analog inputs into 4096 distinct digital codes. This high resolution makes it suitable for applications that require precise measurements, such as data acquisition systems and sensor interfaces.
The device operates at a conversion rate of up to 100 kilosamples per second (ksps) for both channels, allowing for fast and efficient data acquisition. It supports a wide input voltage range from 0 V to the reference voltage, which can be externally programmed. This flexibility enables compatibility with various input signal types and voltage levels.
The AD7862ARS-2REEL offers two fully differential input channels, allowing for the measurement of bipolar signals. Each input channel has a programmable gain amplifier, providing signal amplification to accommodate a range of input voltages. This feature enhances the device's versatility and enables the measurement of signals with different magnitudes
