Analog to digital converters (ADC) are an essential part of data acquisition and signal processing systems. AD7991YRJZ-0RL is a high-performance 8-bit analog to digital converter with integrated programmable gain amplifier (PGA) that is suitable for a wide range of applications. It provides high resolution, low noise, and wide dynamic range for biomedical, industrial process control, and measurement applications.

The AD7991YRJZ-0RL is capable of converting analog input signals from 0 to 4.096V into 8-bit resolution digital codes. The integrated PGA allows for signal conditioning of a wide range of input amplitudes and also provided a programmable gain setting from 1 to 8. The high sampling rate of up to 500ksps makes the device suitable for applications where fast acquisition and data conversion is required. The power consumption is also low, making it suitable for battery-powered systems.

The AD7991YRJZ-0RL supports single-ended analog input signals with a wide input voltage range up to 4.096V. It features an internal reference voltage of 2.048V, which is used to offset the incoming signal and ensure accurate conversion. The zero scale calibration provides exceptional accuracy even in the sub-LSB regions by compensating for any offset error and ensuring precise conversion of low input signals.

The device features an integrated 12-bit asynchronous serial peripheral interface (SPI) compatible master and slave interface. This makes the device suitable for communication with a wide range of microcontrollers. The multi-branch DAC and the integrated analog programmable gain amplifier (PGA) and voltage reference enable precise amplitude adjustment for precise measurements and detection of small changes in the input signal.

The AD7991YRJZ-0RL has an on-chip green, red, and blue (RGB) LED feedback system that allows the user to measure and control the input signal and provide status control, such as an over-range or under-range signal. The device also provides an adjustable sampling frequency capability that allows the user to select a suitable speed for the application.

The AD7991YRJZ-0RL is a monolithic integrated circuit (IC) that provides a high-precision, low-power, 8-bit resolution analog to digital conversion solution with integrated programmable gain amplifier (PGA) for a wide range of applications. Its high resolution, low noise, and wide dynamic range make it suitable for biomedical, industrial process control, and measurement applications. Its integrated 12-bit SPI compatible master and slave interface makes it easy to interface with a wide range of microcontrollers. Its integrated analog programmable gain amplifier (PGA) and programmable gain setting from 1 to 8 makes it very suitable for signal conditioning and accurate measurement of small changes in input signal. Finally, its green, red, and blue LED feedback system makes it suitable for on-the-spot debugging and external observation of system overloads and under-loads.
