The PCM1792ADBG4 is a highly efficient and powerful analogue-to-digital converter (ADC). It has an extremely low-noise level of 5mV (typical) and a high signal-to-noise ratio of 118dB. Its maximum dynamic range is 126dB, and it can operate from a single 3.3V supply. The DAC is highly integrated, featuring a low clock jitter of 1.5nV and 10MHz output current. It is designed for precise data acquisition, digital signal processing, and digital-to-analogue conversion.

The PCM1792ADBG4 has a range of applications in the fields of digital audio, automotive audio and video, and imaging. Its applications in digital audio can include amplifiers, sound systems, audio/video recorders, digital audio workstations, synthesizers and effects processors. With its low noise levels and high signal-to-noise ratio, the PCM1792ADBG4 is a great choice for automotive audio and video applications such as in-car entertainment systems, navigation systems and infotainment systems. Its imaging applications can include CCTV systems, medical imaging, industrial camera systems and surveillance systems.

The PCM1792ADBG4 ADC is a single-channel device that uses a two-stage architecture to achieve maximum dynamic range and low-noise performance. It is based on a 12-bit Delta-Sigma converter with a three-level or four-level delta-sigma modulator. It uses an 8kHz triangular wave as an input, which creates three (or four) fundamental frequency components of 1.5kHz, 3kHz, and 4.5kHz (or 6kHz). These components are used to actively update the sample-and-hold capacitors in the converter.

The first stage of the PCM1792ADBG4 is a low-noise amplifier and sample-and-hold circuit, which enables a high signal-to-noise ratio and wide dynamic range. The second stage is a delta-sigma modulator, which converts the analogue input signal into a digital bitstream. This digital bitstream is then passed through an adjustable third-order low-pass filter, which acts to reduce the effect of high-frequency noise on the signal output. The filtered signal is then output as a 12-bit resolution digital signal.

The PCM1792ADBG4 is an extremely accurate device, with a maximum total harmonic distortion (THD) of -116dB and signal-to- noise ratio of 118dB. It has a WLCSP package for easy handling and it features a range of power-saving features to help increase efficiency. Its automatic power-down feature allows the device to switch between full-power and low-power modes, reducing power consumption and minimizing heat dissipation when not in use. It also includes a power-on reset function and an adjustable clock oscillator.

In summary, the PCM1792ADBG4 is a low-noise, high-resolution ADC that is suitable for a wide range of applications, including digital audio, automotive audio and video, and imaging. Its two-stage architecture enables a maximum dynamic range and low noise performance, while its WLCSP package and power-saving features make it ideal for space conscious designs.
