Working Principle

The ADS7852Y/2KG4 is an 8-bit, dual-channel ADC that uses a successive approximation technique to convert analog input signals into digital values. The successive approximations process involves rapidly changing the comparator’s reference voltages until the resulting digital output matches the analog input.When an input signal is fed into the amplifier, the output of the amplifier is compared to a reference voltage and the result is sent to a successive approximation register (SAR). The SAR then compares the input and reference voltages and the result is sent back to the comparator. From here, the conversion process begins.The ADS7852Y/2KG4 also features a precision temperature sensor which monitors the ambient temperature during conversion. The ADC sample signal is compared to the reference voltage level and a corresponding 8 bit binary signal is output depending on the comparison.

Conclusion

The ADS7852Y/2KG4 is a dual-channel, low-power, 8-bit ADC that is suitable for a variety of applications including those in the automotive, medical and industrial sectors. It features a precision temperature sensor and a programmable 8-bit register that allows users to adjust the device’s configuration parameters. Additionally, it has a low power consumption and a maximum conversion rate of 36kHz.
