ECM P/N 5181 uses TI TLV320AIC23 high resolution audio codecs to provide two channels of Audio input and two channels of Audio output.

Each input channel consists of two inputs a left and a right, and each output channel consists of two outputs left and right. The outputs are muteable. 

ECM P/N 5181 uses TI TLV320AIC23 high resolution audio codecs to provide two channels of Audio input and two channels of Audio output. Each input channel consists of two inputs a left and a right, and each output channel consists of two outputs left and right. The outputs are muteable.

The inputs are capacitor coupled and band pass filtered with cutoff frequencies at 2.6Hz and 1.36Mhz. The input voltage range is 2Vrms and input gain is adjustable from -34.5db to 12db in 1.5db steps, with mute. The Analog to digital converters are specified at 90-dB SNR (A-weighted at 48 kHz).

The outputs are capacitor coupled and band pass filtered with a cutoff frequencies at 4Hz and 1.36MHz. The output voltage range is 1Vrms and drives 10K with 50pF loads. The output SNR is specified at 100-dB SNR (A-weighted at 48 kHz).

Sample rate of 48KHz or 96KHz for the input or output channels, with over-sampling rates of 256fs and 384fs. Eight grounds corresponding to the inputs and outputs ease wiring. A serial identification circuit prevents use with incorrect FPGA IP.

Applications include audio input recording, audio frequency AD and DA conversion and audio outputs.
