TDA1541A-MK4 DAC module

TDA1541A-MK4 DAC module. Twin crystal, balanced ultra low jitter masterclock. Ultra high speed synchronous I2S reclockers. Diode-resistor I2S attenuators. Balanced, DC-coupled DEM clock synchronizer. On-board voltage regulators and power supply filters. 12th order LC power supply filter for masterclock and bit reclocker. Passive I/V conversion with dual JFET current buffer and wirewound bias resistor driving a wirewound Mobius Honeycomb passive I/V resistor. Hybrid output coupling caps. Module accepts Philips I2S and can run in both, NOS and OS mode depending on digital audio source specs. The TDA1541A-MK4 is primarily intended for use with the SD-transport as this combination maintains extreme low jitter and interference levels at both, DAC and digital audio source. Output impedance equals 500 Ohms, output amplitude 2Vpp / 0.707V rms. Minimum load resistance equals 10K, wirewound potentiometer is advised in order to maintain lowest possible noise levels. Failing to observe load specifications can lead to severe sound quality degradation. In order to achieve maximum performance, linear power amplifiers with fewest possible semiconductors or tubes in the signal path are recommended. Digital power amplifiers are not recommended for use with the TDA1541A-MK4 module.
