Introduction

The ADS7818EB/250G4 is an analog-to-digital converter from Texas Instruments. It is a 12-bit converter with voltage input ranges from 0 to 5 V. It provides high speed performance and low power consumption, making it ideal for applications requiring high speed, low power data acquisition.

Application Field

The ADS7818EB/250G4 is widely used in various applications such as audio and video recording and playback, medical imaging, and industrial process control. It is also used in automotive application such as automotive diagnostics, engine control, and emissions control. This device is also suitable for use in a wide range of communication and military applications, particularly those requiring low power consumption.

Working Principle

The ADS7818EB/250G4 is a 12-bit analog-to-digital converter. It converts an analog input signal into a digital output. The analog input signal is first digitized by a track and hold circuit. The resulting digital signal is then amplified, and converted into a 12-bit number. The output is a 12-bit two\'s complement binary number with a resolution of 0.4 mV. The conversion time is very fast, with a sampling rate up to 1MSPS.

Power Consumption

The ADS7818EB/250G4 is designed for low power consumption, making it ideal for low power applications. It operates on a 3.3V power supply, and has a very low power dissipation of only 0.34 mW when operating at 1MSPS. This makes it suitable for applications requiring both low power, and high speed performance.

Features

The ADS7818EB/250G4 features an on-chip Programmable Gain Amplifier (PGA), allowing for a wide range of input signals. It has a large input range, allowing for both low level and high level inputs. It also includes an internal temperature sensor, allowing for accurate temperature measurement.

Conclusion

The ADS7818EB/250G4 is a high performance, low power analog-to-digital converter. It offers fast conversion speeds and a wide range of input signals. Its low power consumption makes it particularly suitable for low power applications. In addition, its on-chip PGA, wide input range, and internal temperature sensor make it ideal for a range of applications such as audio, video, medical imaging, process control, and automotive diagnostics.
