Working Principle

The working principle of the AD7829BRUZ-REEL7 is based on a single-slope integrating architecture. The ADC contains an integrating capacitor, reference voltage and multiplexed inputs. When a voltage is applied to the input, the voltage across the integrating capacitor increases until the output is equal to the reference voltage. The output of the ADC is then converted to a digital output by a digital-to-analog converter (DAC).The AD7829BRUZ-REEL7 uses a cyclic succession of the analog-to-digital conversion process. This process is then used to calculate the output digital value.The ADC operates in the 3V single-supply environment and provides 12-bit resolution. The reference voltage is internally generated from the 8 μA quiescent current. The converter also has a wide analog input range from 0 - 3V and an operating temperature range of -40 °C to +85 °C.

Conclusion

The AD7829BRUZ-REEL7 is a low cost, low power ADC for 12-bit resolution applications. This ADC is designed to operate from a single 3V supply and supports a variety of analog input ranges. It has several key features and benefits, including high throughput, high accuracy, low power consumption, wide input range, and robust design. The ADC is suitable for applications such as analog-to-digital conversion for video systems, industrial system control, instrumentation, scientific data acquisition, and medical applications.
