Midas M8000 115 dB, 192 kHz, 8-Channel A/D Converter (LQFP-48L)

 Loading product data...

The M8000 is a complete 8-channel analog-to-digital converter for digital audio systems. It performs sampling, analog-to-digital conversion, and anti-alias filtering, generating 24-bit values for all channel inputs in serial format at sample rates up to 216 kHz per channel.

The M8000 is ideal for high-end and pro-audio systems requiring unrivaled sound quality, transparent conversion, wide dynamic range and negligible distortion, such as A/V receivers, digital mixing consoles, multi-channel recorders, outboard converters and digital effects processors.

This device is pin-for-pin compatible with the CS5368.

The M8000 uses a 5th-order, multi-bit delta sigma modulator followed by low latency digital filtering and decimation, which removes the need for an external anti-aliasing filter. The ADC uses a differential input architecture which provides excellent noise rejection.

Dedicated level translators for the Serial Port and Control Port allow seamless interfacing between the M8000 and other devices operating over a wide range of logic levels. In addition, an on-chip oscillator driver provides clocking flexibility and simplifies design.

The M8000 supports a high-speed TDM interface which provides a serial output of 8 channels of audio data with sample rates up to 216 kHz within a single data stream. This reduces layout complexity and relieves input/output constraints in digital signal processors.
