The BH7673G-TR is a Video IC (isolation amplifier) manufactured by ROHM. It is designed to isolate audio and video signals from digital noise. It features a wide operating voltage of 3.0V to 3.6V, low power consumption of only 130µA, and a low cut-off frequency of 20Hz. This amplifier has a signal-to-noise ratio (SNR) of -97dB, which allows it to filter and distinguish digital signals from noise. It also contains transistors, resistors, and capacitors that prevent electromagnetic interference (EMI) from degrading the quality of the audio and video signals. This IC is commonly used for HDMI, D-Sub, SCART, component video and composite video applications.
