DSD1792DBR Application Field and Working Principle

The DSD1792DBR chip is a digital-to-digital differential operational amplifier, which belongs to special purpose ADCs and DACs for data acquisition. It is characterized by low power consumption, high speed, wide bandwidth and excellent isolation characteristics.
The DSD1792DBR is a very cost-effective integrated circuit, and its wide application field won’t let people down. Firstly, it can be widely used in high-resolution data acquisition systems. The small size, low power consumption and high precision of the chip can help engineers to reduce the thermal effect and the cost of the design. Secondly, with the help of its wide bandwidth, high gain and low distortion, DSD1792DBR is able to drive a speaker directly, making itself a valuable medium for digital audio amplifier applications. Finally, DSD1792DBR is also suitable for many other audio applications such as professional microphones, power amplifiers and surround-sound processors.
As for its working principle, it is mainly based on the differential distortion cancellation circuit, which is capable of realizing the gain adjustment, lowering the distortion and hence making the audio signal much clearer. The chip works in the following steps: the signal is amplified by the differential amplifier, then goes through low-pass filtering to suppress high-frequency noise, and then is adjusted by the gain of the two differential input stages and fed back by the high and low feedback switches. With the help of this feedback loop, the distortion cancellation is realized and the output signal is generated in the end.
