Working Principle of ICL7117CMH+D

The ICL7117CMH+D is a dual-channel ADC and DAC which uses a combination of voltage-to-frequency (V/F) and pulse-width modulation (PWM) techniques to convert analog signals to digital form and vice versa. It has a wide dynamic range, making it suitable for use in a variety of environments. By using a combination of these two techniques, the ICL7117CMH+D achieves extremely high accuracy and precision in data conversion.

The ICL7117CMH+D has a pair of on-chip voltage-controlled oscillators. These oscillators produce a square wave whose frequency is dependent on the voltage level of the analog signal being converted. This is known as the V/F method. The frequency of the output square wave is then converted to a digital signal using a PWM technique. This technique results in a digital signal that is a direct representation of the analog input.

The ICL7117CMH+D also has a 16-bit internal digital filter. This is used for noise reduction and for improving the accuracy and precision of data conversions. The ICL7117CMH+D is also capable of automatically calibrating itself, eliminating the need for manual adjustments and additional components.

Conclusion

The ICL7117CMH+D is a versatile ADC/DAC converter that is widely used in data acquisition applications. It is capable of quickly and accurately converting digital and analog signals thanks to its combined V/F and PWM techniques. The ICL7117CMH+D also has an on-chip digital filter and is capable of self-calibration, making it an ideal choice for a wide range of applications, including medical imaging, industrial robotics, automotive systems, telecommunications, and consumer electronics.
