AK5720
96kHz 24-Bit  ADC
1. General Description
The AK5720 is a low voltage 24-bit A/D converter for digital audio systems. The AK5720 includes an
Input Gain Amplifier, making it suitable for microphone applications. The analog signal input of the
AK5720 is single-ended, eliminating the need for external filters. The AK5720 is housed in a
space-saving 16-pin TSSOP package.
