Working Principle

The AS1541-BQFT is a low-to-medium speed analog-to-digital converter. It samples the input voltage using a sample and hold circuit, followed by a comparator. The comparator compares the input voltage with a reference voltage, which is then converted into a digital signal using a sigma-delta modulator. The output of the sigma-delta modulator is then converted into a digital value by a digital-to-analog converter (DAC). This output is then stored in a digital memory.

The ASIC\'s programmable control registers allow the user to configure various parameters such as the reference voltage, sampling rate and accuracy. The device also has low-power sleep mode and a built-in temperature-compensated oscillator (TCO) for power savings.
