The AD7890BNZ-4 is an Integrated Circuit (IC) component that offers high-precision and high-speed analog-to-digital conversion. It is a 12-bit successive approximation Analog-to-Digital Converter (ADC) designed by Analog Devices Inc.
Key features of the AD7890BNZ-4 include:
1. Resolution: The ADC offers a resolution of 12 bits, meaning it can convert analog signals into digital values with 2^12 (4096) distinct steps.
2. Sampling Rate: It provides a fast conversion rate of up to 400 kilosamples per second (ksps), allowing for rapid and accurate analog signal sampling.
3. Input Range: The AD7890BNZ-4 has a wide input voltage range of -10V to +10V, enabling it to convert signals that span across a wide range of voltages.
4. Analog Inputs: It features an analog input multiplexer with up to 8 single-ended inputs or 4 differential inputs. This enables the ADC to handle multiple analog signals simultaneously or process differential signals for better noise rejection.
5. Power Supply: The IC operates with a single power supply voltage ranging from +2.7V to +5.25V, offering flexibility in various system designs.
6. Serial Interface: It includes a Serial Peripheral Interface (SPI) that allows for easy communication with microcontrollers and other digital devices. The SPI interface provides straightforward control and configuration of the ADC
