CS5342_06中文资料凌云逻辑数据手册PDF规格书

General Description

The CS5342 is a complete analog-to-digital converter for digital audio systems. It performs 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 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 available in a 16-pin TSSOP package in Commercial grade (-10° to 70° C). The CDB5342 Customer Demonstration board is also available for device evaluation and implementation suggestions. Please refer to “Ordering Information” on page 21 for complete ordering information.

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.
