ADC1113S125HN-C1 is a monolithic integrated circuit (IC) used for data acquisition. It belongs to the Analog to Digital Converters (ADC) family and is used to convert analog signals into digital signals. It is composed of a successive approximation register (SAR) ADC, a voltage reference and a voltage-to-time converter. It is usually operated within an ambient temperature of 0°C to 70°C.

The ADC1113S125HN-C1 is designed to provide an excellent signal to noise Ratio (SNR) and high dynamic performance, thus making it suitable in a variety of applications. Commonly, it is used for industrial sensing, computer communications, and automation, among many others. It is also one of the preferred choices for applications that require wide dynamic ranges, including dynamic range of up to 11-bits. In some cases, it is even used beyond 11-bits, such as providing a resolution of 12 bits.

When it comes to the working principle of ADC1113S125HN-C1, it uses the SAR method which employs successive approximation to determine the digital equivalent of an analog input voltage. The SAR method helps in achieving high resolution, conversion speed and low power consumption when compared to other methods. The detailed operation of the SAR method is described in the following.

The ADC1113S125HN-C1 starts by taking a sample of an incoming analog signal and stores it in the sample-and-hold circuit. After that, it starts the analog-to-digital conversion procedure by applying successive approximation to determine the digital value of the incoming analog signal. First, it applies a voltage slightly higher than the sample-and-hold reference voltage to measure the analog input. If the analog input is higher than the applied voltage, then it will toggle a bit to one in the SAR and apply a voltage lower than the reference voltage. If the analog input is lower than the applied voltage, then it will toggle the same bit to zero in the SAR and keep applying higher voltages until the analog input is matched with the voltage in the SAR register. This process is repeated for all the bits in the SAR, thus giving the digital value of the existing analog input.

In conclusion, ADC1113S125HN-C1 is a highly reliable monolithic IC used for data acquisition and is one of the many choices for applications that require wide dynamic ranges, including dynamic range of up to 11-bits. It is characterized by excellent SNR, high dynamic performance and uses the SAR method to achieve high resolution, conversion speed and low power consumption. The ADC1113S125HN-C1 is suitable in a variety of applications, such as industrial sensing, computer communications, and automation, among many others.
