Analog-to-digital converters (ADC) are essential elements in data acquisition. They convert analog signals into digital signals with high accuracy. The ADS8345NB/1K is an integrated analog-to-digital converter with 8-bit resolution and 200 Ksps sampling rate. It is widely used in industrial applications.

The ADS8345NB/1K combines an 8-bit A/D converter with a 1.8 V to 5.25 V voltage reference in a single package. In addition, the device has a high-impedance analog input with a programmable input range of ±2.5 V, ±5 V, ±10 V, and ±20 V ranges. It also has a 32-step external voltage reference allowing users to adapt the converter to their system requirements. For this precision ADC, its basic specifications include maximum sampling rate, error handling, overvoltage protection, analog input channels and It has higher EMI immunity and provides power supply noise rejection.

In terms of the working principle of the ADS8345NB/1K, this ADC is extremely flexible and offers a wide range of features to support various applications. It starts integrating the input signal after receiving a single convert command from the system. After the integration period, it converts the integrated value into digital code. The conversion time is controlled by an external clock between 33 MHz and 0.63 MHz and the internal clock is used during the conversion process.

The ADS8345NB/1K is a fast, low-power, and high-accuracy ADC which is suitable for various applications. It’s often used in sensors, actuators, and other data acquisition applications, such as medical instrumentation, industrial process control, automotive and avionics systems. With its low-power operation and high accuracy, it is the most suitable ADC for power-sensitive applications and it can easily convert low-frequency signals without any additional components or external circuitry.

As an example, this ADC can be used in accelerometer applications. Acceleration is usually measured by a capacitive sensing element that is connected to the ADC. The voltage output of the accelerometer is proportional to the acceleration, and the ADC will process it accordingly. The ADC integrates the signal and converts it into digital code with 8-bit resolution. This can be monitored and used to measure acceleration in both directions. In addition, this ADC can also be used in load cell applications for precise weight measurement.

The ADS8345NB/1K has low power consumption and a high degree of accuracy and repeatability. Its wide input range, low EMI and noise immunity, and high-accuracy conversion make it a great choice for many different industrial applications. This integrated ADC is an ideal solution that provides accuracy and control with a cost-effective design, allowing application designers to meet their requirements with a flexible, low-power solution.
