Data acquisition is a technique used in many modern engineering, scientific, and commercial applications to provide precise information on the electrical, physical, and biological characteristics of the external environment. ADCs and DACs are the two main components used in data acquisition systems, and the CDK3404ATQ48X is a special purpose ADC/DAC that has a range of applications and a unique working principle.

The CDK3404ATQ48X is a low power, high accuracy, quad analog-to-digital converter. It is ideal for applications in consumer, industrial, medical, and automotive markets, as well as for military/aerospace applications. It is capable of converting signals from external sources such as microphones and sensors into digital values that can then be further processed by the system. The CDK3404ATQ48X is designed to operate at a low power consumption, even when performing a high sampling rate. It is also designed to provide a high dynamic range, increased resolution, better signal-to-noise ratio, and low self-biasing offset voltage.

The CDK3404ATQ48X converts analog signals into digital values using a two-stage conversion process. In the first stage, the analog signal is sampled using an internal high-speed or external sample-and-hold circuit. The sampled analog signal is then digitized using a high-resolution successive approximation register (SAR) ADC. The SAR architecture consists of an analog comparator and a five-bit current-mode DAC to generate the reference voltage. The analog comparator compares the reference voltage with the input signal, and the result of the comparison is sent to a latch. The information in the latch is then converted into digital form by the SAR ADC converter.

The output data from the CDK3404ATQ48X is in the form of a single-ended, twos complement digital value. Furthermore, the device features an analog watchdog circuit, which is constantly monitoring the analog input signals and compares them with the programmed alarm level. If the alarm level is exceeded, the device will send out a programmed digital output. This is useful for fault detection and protection applications.

The CDK3404ATQ48X also provides digital-controlled gain control, which increases or decreases the conversion output range. This is beneficial for range selecting and offset level control, and is useful for applications where the input signal range is dynamically changing. In addition, the device has an on-chip temperature sensor that can measure the die temperature with a resolution of ±1°C.

The CDK3404ATQ48X is a versatile quad ADC/DAC that is suited for a wide variety of applications. Its low power requirements, high accuracy and robust features make it an ideal device for use in a wide range of applications, including medical and automotive, military and aerospace, industrial, and consumer markets.
