Working principle:

The working principle of the KAD5512P-21Q48 is based on a single-ended 12-bit Sigma-Delta ADC topology. The device uses a 14-bit 1.5 MS/s sigma-delta modulator to convert the analog input signal into a digital signal with a high signal to noise ratio (SNR). The modulator uses an asymmetric switch to control the current in a digitally programmable feedback loop. The modulator then uses the feedback loop to generate an oversampled output to the A/D converter. The A/D converter feeds the output into a 5-bit pipeline register to reduce the sampling ripple and the continuous time integration circuit (CIC) to reduce the amount of time it takes to process the input signal. The KAD5512P-21Q48 then quantizes the signal and outputs the 12-bit digital result.

The KAD5512P-21Q48 enables engineers to make precise measurements with a high signal to noise ratio (SNR) and wide dynamic range. It has low power consumption and a wide temperature operating range, making it suitable for a variety of applications. The device can be operated from a single 3.3V power supply and has a parallel output mode for easy data access. It is also compatible with many popular digital bus standards such as SPI, I2C and Serial Peripheral Interface to allow for easy system integration.

The KAD5512P-21Q48 analog-to-digital converter offers a robust, highly integrated solution for applications such as low-noise signal acquisition, instrumentation, process control, data acquisition and data collection. It provides excellent dynamic performance and signal-to-noise ratio, and is suitable for use in harsh environments. In addition, it is easy to program and configure, making it ideal for a variety of applications.
