Working Principle of the AD7228KPZ

The AD7228KPZ is a low-power, multi-output MDAC that functions by sampling and storing up to four digital inputs (i.e., DIN0 to DIN3). These digital inputs are fed into an analog signal-processing block, which contains a buck converter, a charge-pump filter, and a buffer amplifier. The analog signal-processing block functions by converting the digital signals into an analog voltage that is proportional to the digital signal.

The analog signal-processing block functions by converting the digital input signals into repetitive digital pulses and shifting these pulses through the charge-pump filter to generate an output voltage. The charge-pump filter functions by removing most of the pulsation noise and any DC offset. The buffer amplifier then functions to further condition and buffer the resulting analog signal, producing a low-noise and high-bandwidth output.

The interface logic of the AD7228KPZ enables the device to write up to four DAC outputs simultaneously. This enables it to generate an analog voltage that is proportional to multiple digital inputs, making it ideal for a variety of applications requiring simultaneous, precision linear control.

Conclusion

The AD7228KPZ is a low-cost, low-power, multi-output MDAC suitable for a variety of data acquisition applications where multiple DAC outputs need to be synchronized and updated simultaneously. Its fast settling times, low power consumption, and buffered outputs make it an ideal choice for simultaneous control and measurement functions, optical and electrical imaging and precision linear control.
