Description

The AD1871 is a stereo audio ADC intended for digital audio applications requiring high performance analog-to-digital conversion. It features two 24-bit conversion channels each with programmable gain amplifier (PGA), multi-bit sigma-delta modulator and decimation filters. Each channel provides 97 dB of THD+N and 107 db of Dynamic Range making the AD1871 suitable for applications such as Digital Audio Recorders and Mixing Consoles.
