ADCS7476AIMFX/NOPB is an analog-to-digital converter (ADC) designed for high accuracy, low power dissipation, and excellent linearity. It is intended for use in a wide variety of application fields, including analog signal conditioning, data acquisition and control, digital signal processing, and measurement, monitoring and control. The ADCS7476AIMFX/NOPB is a single-channel 18-bit ADC with a serial digital input. It accepts analog inputs from 0.2V to 4.75V with a 1.2V reference voltage input. The full-scale dynamic range is 16.47V with a 17.85V analog input tolerance range. The ADC has a programmable data-input filter for unwarranted noise suppression. The sampling rate of the ADC is up to 500ksps and it is designed to provide an output data resolution of 0.05V. When it comes to accuracy and linearity, the ADCS7476AIMFX/NOPB is an excellent choice. It has an unmatched signal-to-noise ration of 79dB, and a total effective number of bits (ENOB) of 16.8. The full-scale offset error is ±0.5 LSB, while the gain accuracy is ±0.1 LSB (with 0.2V reference). The linearity error ranges from -3.3 LSB to 3.3 LSB. In terms of power consumption, the ADCS7476AIMFX/NOPB is a great solution. It has an integrated low drop-out linear regulator to regulate its supply voltage, so it can operate with a supply voltage range from 5V to 7.5V. The typical quiescent current of the ADC is 10mA, and the typical standby current is 11.5µA, providing an excellent balance between power efficiency and performance.In terms of its working principle, the ADCS7476AIMFX/NOPB adopts a single-slope delta-sigma modulator architecture. In this architecture, the input signal is sampled and converted by the modulator in a one-bit parallel data format. The output of the modulator is then sent to a decimation filter to reduce the sample rate and harmonic distortion before being sent back to the ADC for further processing and finally sent to an output register for storage before being read via the serial data output port. In conclusion, the ADCS7476AIMFX/NOPB is a great choice for analog-to-digital conversion. It offers excellent accuracy and linearity, low power dissipation, and a wide operating voltage range. Its single-slope delta-sigma modulator architecture ensures that its outputs are free from unnecessary noise and distortion.
