General Description

The PA5240 is a low cost stereo analog to digital converter.

The PA5240 can accept I2S or Left Justified serial audio data format up to 24-bit word length.

The device uses advanced multi-bit ∆-∑ modulation technique to convert signals from analog to digital.

The multi-bit ∆-∑ modulator makes the device with very low sensitivity to clock jitter and very low out of band noise.
