Working Principle

The ADC121S051EVAL evaluation board uses the Texas Instruments ADC121S005 ADC for analog-to-digital conversion. The ADC121S005 ADC is a low-power, wide-range, 12-bit converter with a sampling rate of up to 3.3 Msps. The board supports single-ended and differential analog inputs. It is based on the successive-approximation (SAR) architecture and uses a dual-slope integration (DSI) technique for error correction.

When an analog signal is applied at the analog input of the ADC121S051EVAL, the ADC121S005 ADC converts the analog signal into a digital signal and sends it to the digital output. The ADC121S005 ADC employs a succession of comparators and a sequencer which compares the analog input signal to a succession of reference voltages. The comparator determines the analog signal’s step size and sends it to the succeeding comparator. The process is repeated until the analog signal is fully converted to a digital signal.

The ADC121S005 ADC supports simultaneous sampling of multiple analog inputs. Each of the analog inputs is multiplexed with the internal voltage reference. The ADC121S005 ADC has a programmable internal reference voltage which ensures a low-noise, low-offset, and high-accuracy conversion performance. It also features power-down and power-save modes for power saving.

Conclusion

The ADC121S051EVAL evaluation board is a powerful tool for rapid and accurate analog-to-digital conversion of analog signals. The board incorporates a Texas Instruments ADC121S005 ADC which uses a low-power, wide-range, 12-bit, 3.3Msps ADC. The board supports single-ended and differential analog inputs and is capable of achieving high-fidelity measurement results.
