CS5342

CS5342 105 dB, 192 kHz, Multi-Bit Audio A/D Converter Features General Description z Advanced multi-bit Delta-Sigma architecture z 24-bit conversion z Supports all audio sample rates including 192 kHz z 105 dB Dynamic Range at 5 V z -98 dB THD+N z High pass filter to remove DC offsets z Analog/digital core supplies from 3.3 V to 5 V z Supports logic levels between 1.8 V and 5 V z Linear phase digital anti-alias filtering z Auto mode selection z Pin-compatible with the CS5340 and CS5341 The CS5342 is a complete analog-to-digital (A/D) converter for digital audio systems. It performs sampling, A/D 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 CS5342 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 CS5342 is ideal for audio systems requiring wide dynamic range, negligible distortion, and low noise, such as set-top boxes, DVD-karaoke players, DVD recorders, A/V receivers, and automotive applications.
