AK5522VN

The AK5522VN is a 32-bit A / D converter supporting sampling frequencies from 8kHz to 192kHz, developed for line and microphone digital audio equipment. 108dB of dynamic range and 98dB S / (N + D) is achieved with low power consumption. There are four types of digital filters that can be selected according to the application.
 The AK5522VN has excellent power supply rejection ratio (PSRR), and high input common mode rejections (CMRR). Excellent performance can be achieved even with USB bus power or a DC-DC converter outputs directly connected to the power supply. The AK5522VN is suitable for a USB audio interface, wireless speakers, automotive audio equipment, etc. in severe power supply environments.

The AK5522VN has a built-in voltage regulator output with high PSRR. It can be used for a DAC such as the AK4432VT or AK4452VN, which makes it is possible to maximize DAC performance with poor quality power supplies. In addition, an internal low jitter PLL generates a master clock output for the DAC and other system components from LRCK or BICK. Thus, low EMI solutions can be achieved by the reduction of unnecessary high frequency master clock traces on the printed circuit board.
