The AD7890AN-2 is an Integrated Circuit (IC) component that is designed for precise analog-to-digital conversion. It is manufactured by Analog Devices, a renowned semiconductor company. The AD7890AN-2 is part of the AD7890 series of analog-to-digital converters (ADCs) and offers high conversion accuracy and speed.
One of the key features of the AD7890AN-2 is its 12-bit resolution, which allows it to convert analog signals into digital values with a high level of precision. This resolution enables it to provide accurate measurements in various applications such as industrial automation, data acquisition systems, and instrumentation.
Another notable feature of the AD7890AN-2 is its fast conversion rate. It is capable of performing conversions at a rate of up to 100 kilosamples per second (ksps). This faster conversion speed ensures that real-time data can be acquired and processed rapidly.
The AD7890AN-2 operates with a single analog input channel. It has a wide input voltage range, typically ranging from 0 to Vref, where Vref represents the reference voltage supplied to the ADC. The broad input voltage range accommodates a wide variety of analog signal sources.
Furthermore, the AD7890AN-2 incorporates a successive approximation register (SAR) architecture that aids in its accurate conversion performance. The SAR architecture uses a binary search algorithm to iteratively approximate the input signal, resulting in precise digital representation
