Additional Details

Given Champion Microelectronic Corp's focus, this codec likely supports standard audio sampling rates (e.g., 44.1kHz, 48kHz) and bit depths (e.g., 16-bit, 24-bit). It probably includes features such as headphone amplification, line-in/line-out support, and microphone input. The specific features and performance characteristics would depend on the particular implementation and configuration. The 'TR' suffix suggests a tape and reel packaging for automated assembly. Unfortunately, due to the scarcity of publicly available information, more specific details remain inaccessible.
