The AD7899ARS-3 is an integrated circuit (IC) component manufactured by Analog Devices Inc. It is a high-performance, low-power, 12-bit analog-to-digital converter (ADC) designed for use in various applications that require accurate conversion of analog signals into digital data. This overview will discuss the key features and capabilities of the AD7899ARS-3.
The AD7899ARS-3 operates with a supply voltage ranging from 2.7V to 5.25V, making it suitable for both battery-powered and industrial applications. It has a maximum sampling rate of 100 kilosamples per second (ksps) and provides a 12-bit resolution, enabling precise conversion of analog signals. The IC employs a successive approximation register (SAR) architecture for achieving accurate and reliable conversions.
One of the crucial features of AD7899ARS-3 is its excellent linearity, offering a maximum integral non-linearity (INL) and differential non-linearity (DNL) of ±1 LSB (Least Significant Bit). This ensures minimal distortion and precise representation of the analog input. Furthermore, the IC supports a wide input voltage range of ±2.5V, allowing for flexible interfacing with different signal sources.
The AD7899ARS-3 provides a built-in reference voltage generator, which eliminates the need for external voltage references. It offers two selectable reference voltages, namely, VREF+ and VREF-
