The ADS8345E/2K5G4 is a high performance, low-power, 12-bit, low voltage analog to digital converter (ADC). It supports input voltage between 0.2 V to 5.6 V and output data rate up to 2.5 MSPS. It is ideal for applications in the field of data acquisition, such as position detection and power measurement, where high accuracy and resolution is required.

The ADS8345E/2K5G4 is based on SAR or successive approximation register architecture. This architecture converts the analog voltage from an analog source into a digital output code by successive approximations. The conversion starts with the full-scale range, which is divided into two halves and then into four quarters and so on. The result of each approximation step is compared with the input voltage, and the final output code is thus obtained. This process takes about 11 clock cycles and results in 12-bit resolution and accuracy.

The Features of this ADC include high sampling rate, low power consumption, low offset and high linearity. It is also capable of rejecting 50 Hz and 60 Hz power line interference and can operate on supply voltages as low as 3.3 V and 5 V. The power dissipation per conversion step is very low and is maintained at around 160 µW. This helps to achieve extended battery life and reduce system costs.

The ADS8345E/2K5G4 can be used in a variety of applications, ranging from position detection in industrial automation, to power measurement in consumer electronics and energy management. It is also suitable for medical and healthcare applications, for example, for monitoring electrocardiogram (ECG) signals. It is also widely used in test and measurement, automotive, and consumer products.

Due to its high resolution and accuracy, the ADS8345E/2K5G4 is suitable for applications that require precise digital signals for control and monitoring. It is designed to minimize power consumption and noise, which makes it ideal for battery powered systems. Its robust features, low power consumption and digital output which can be interfaced to most electronic systems, makes it a suitable choice for data acquisition.
