Technical Specifications

The ADC 1002S020HL/C1 is a low-powered device with a maximum operating current of only 120mA. This converter has an integrated temperature-compensated oscillator, allowing it to achieve a sampling rate of 600 ksps while maintaining a low level of power consumption. The maximum power supply voltage rated for this converter is 5 VDC, and its flexible DC performance allows it to operate with a wide range of supply voltages, making it suitable for use in applications that require low-power draw and/or high levels of integration. The resolution of the ADC 1002S020HL/C1 is 10-bits, and it has a 120-Ohm differential input impedance. Additionally, the converter has a voltage reference accuracy of 0.5%, and it has a power-on reset feature to ensure the output is properly initialized.

Working Principle

The ADC 1002S020HL/C1 uses a successive approximation register (SAR) to convert an input analog signal into a digital code. The SAR works by successively comparing the analog signal to an internally generated reference voltage. Each comparison is done during successive clock cycles and the result is stored in an internal register (SAR register). When the number of comparisons it has completed matches the number of bits in the converter’s resolution, the converter outputs its digital code.

Conclusion

The ADC 1002S020HL/C1 is an analog-to-digital converter which is used in a wide range of applications in the medical, industrial, commercial, and audio/visual streams. It has a resolution of 10 bits, a sample rate of 600 ksps, and a differential input impedance of 120 Ohms. Additionally, it has a voltage reference accuracy of 0.5%, and its maximum operating current is only 120mA. The ADC 1002S020HL/C1 works using a SAR technique, wherein analog signals are compared to internally generated reference voltages in successive clock cycles in order to obtain a digital code.
