Analog Output Configurations
Information on hardware-control stereo audio DAC
The new generation iSAudioPlayer 2.0 contains a TAD5242 hardware-control stereo audio DAC with 120dB dynamic range, and headphone and line driver.
The device supports playback of two channels using the high-performance stereo DAC. The device consists of two pairs of analog output pins (OUTxP and OUTxM) which can be configured in single-ended or differential input mode by setting MD4 and MD5 pins. The input source for these channels is from TDM/I2S/LJ interface. The table below shows the analog output configuration modes available with MD4 and MD5 pins.
| MD5 | MD4 | ANALOG OUTPUT CONFIGURATION |
|---|---|---|
| Low | Low | Differential Output; Line-out only |
| Low | High | Differential Output; Receiver/Headphone load or Line-out |
| High | Low | Single-ended output; Line-out only |
| High | High | Pseudo differential output with external common-mode sense; Headphone load only |
