IC component AD7872TQ is a high-performance, dual-channel, 12-bit Analog-to-Digital Converter (ADC) designed for industrial applications. It offers several key features that make it highly suitable for precision measurement and data acquisition systems.
Firstly, the AD7872TQ incorporates two independent ADCs, providing dual-channel simultaneous sampling capability, which greatly enhances system accuracy and synchronicity. This feature enables the device to capture and convert signals from multiple sources simultaneously, enabling precise measurements of dynamic signals or fast-changing inputs.
With a resolution of 12 bits, the AD7872TQ can convert analog signals into digital form with exceptional precision. This high resolution results in accurate representation of analog inputs, minimizing quantization errors and ensuring reliable performance in applications that require precise measurements.
The AD7872TQ delivers a programmable sampling rate, offering flexibility to optimize the conversion speed based on specific application requirements. It supports four selectable sampling rates, ranging from 100 to 750 kilosamples per second (ksps). This versatility allows the device to accommodate a wide range of input signal frequencies and capture fast-changing signals with high accuracy.
To further improve accuracy, this IC offers an integrated reference buffer, ensuring stable and accurate voltage references during the conversion process. It also provides an internal voltage reference, eliminating the need for an external reference source and simplifying system integration.
The AD7872TQ also features an on-chip sequencer that enables automatic channel selection during conversions
