WM8737CLGEFL

The WM8737CLGEFL is a silicon-based very low-power and low-voltage integrated analog-to-digital converter. It is a single-supply converter with a wide range of operating voltage supply from 1.62 to 6 Volts, and is capable of high speed (630 kHz) and low power (single-ended 5mW) analog-to-digital conversion. It is designed for applications where low power consumption is necessary, such as medical and portable equipment. It is available with both an internal and external clock, allowing for very low power operation.

The main use of the WM8737CLGEFL is in data acquisition applications, where the analog input signal is converted to a digital output by the ADC. This digital output can then be used for data storage, analysis, or further processing. The ADC has a wide range of input voltage ranges from 0V to 3V, which means it can be used for both AC and DC signals. The various features of the WM8737CLGEFL include low power consumption, wide input voltage range, high conversion rate, and internal or external clock support.

Working Principle

The WM8737CLGEFL operates using a successive approximation register (SAR) architecture. This architecture is used due to its good linearity and low power consumption. The architecture works by turning on the internal comparator at the start of every conversion cycle. The output of the comparator is then used to decide whether an output should be set or reset. This is then repeated until the correct logic value has been set or reset. Once the correct logic value is determined, the conversion is complete.

The WM8737CLGEFL also supports an external clock, which reduces the power consumption even further. The external clock has to be of the same frequency or higher than the internal clock. In addition, the external clock can be used to control the start or stop of the ADC conversion cycle. This allows for low power consumption when the ADC is not being used.

Application Field

The WM8737CLGEFL can be used for a variety of applications including data acquisition of both AC and DC signals, process monitoring, security and surveillance, robotics, audio and video recording and playout, industrial and medical instrumentation, and energy management. The low-power feature makes it particularly suitable for battery-operated applications.

Data acquisition applications are one of the main uses for the WM8737CLGEFL, due to its low power consumption and wide range of input voltage. It can be used to convert analog input signals into digital output signals which can be stored, analysed or further processed. The external clock feature allows the ADC to be run at a very low power when not in use.

The WM8737CLGEFL can also be used for audio and video recording and playout. It can be used to capture analog audio and video signals by converting them to digital signals. This can then be used for high-quality recording and playback. The low power feature also makes it well-suited for this application.

The WM8737CLGEFL can also be used in medical and industrial instrumentation. Its low power consumption and low voltage supply make it a popular choice for medical devices such as heart monitors and other medical monitoring equipment. The wide voltage range also makes it suitable for industrial instruments like pressure gauge and current sensors.

Conclusion

The WM8737CLGEFL is a low-power, low-voltage integrated analog-to-digital converter with wide input voltage range and high conversion rate. Its main use is in data acquisition applications, but it can also be used for audio and video recording and playout, industrial instrumentation, and medical instrumentation. The internal and external clock support, along with its wide voltage range, makes it a popular choice for applications where low power consumption is necessary.
