The AD7482AST is an integrated circuit (IC) component developed by Analog Devices. It is a high-speed, dual-channel, 12-bit analog-to-digital converter (ADC) that offers high performance and versatility for various applications.
One of the key features of the AD7482AST is its high-speed sampling rate of up to 3 megasamples per second (MSPS). This allows for accurate and fast conversion of analog signals into digital data, making it suitable for applications that require real-time signal processing.
The ADC supports a wide input voltage range of 0V to VREF, where VREF can be anywhere between 2.5V and 5V. This flexibility in input voltage range enables compatibility with a variety of sensor types and signal sources.
The AD7482AST utilizes a successive-approximation register (SAR) architecture, which ensures reliable and precise data conversion. It has two analog input channels, which can be independently configured as single-ended or differential inputs. This dual-channel capability makes it ideal for applications such as data acquisition systems, multi-channel sensors, and industrial process control.
Another notable feature of the AD7482AST is its built-in voltage reference. This on-chip reference eliminates the need for an external reference source, simplifying the design and reducing component count. The ADC also provides a separate reference input pin that allows for the use of an external reference if desired
