The AD7945AN-B is an integrated circuit (IC) component manufactured by Analog Devices. This IC belongs to the AD7945 family of low-power, 12-bit analog-to-digital converters (ADCs) with a high-speed serial interface. It is designed to convert analog signals into digital data, making it suitable for various applications in industries such as industrial automation, instrumentation, and communication equipment.
Key features of the AD7945AN-B include:
1. Resolution: The AD7945AN-B is a 12-bit ADC, which allows it to provide 4096 possible digital output codes, resulting in excellent accuracy and precision in converting analog signals.
2. Sampling Rate: This IC offers a maximum sampling rate of 500 kilosamples per second (ksps), enabling fast conversion of analog inputs into digital data. The fast sampling rate is vital in applications that require real-time data processing.
3. Analog Inputs: The AD7945AN-B has four differential analog input channels, labeled AIN1, AIN2, AIN3, and AIN4. These channels can handle external analog signals in the range of 0 to VREF, where VREF refers to the reference voltage provided to the IC.
4. Reference Voltage: It requires an external reference voltage for accurate conversion. The AD7945AN-B supports both internal and external reference voltages. The internal reference voltage can be enabled by connecting the REF_SEL pin to the desired reference voltage terminal
