The MS7125 is a low cost 20-pin analog-to-digital converter for digital audio systems. MS7125 can sampling, analog-to-digital conversion, and anti-alias filtering, generating 24-bit values for both left and right inputs in serial form at sample rates up to 200 kHz per channel. The MS7125 uses a 5th-order, multi-bit Delta-Sigma modulator followed by digital filtering and decimation, which removes the need for an external anti-alias filter. The MS7125 is ideal for audio systems requiring wide dynamic range, negligible distortion and low noise.
