3.07 – Settings and Input wiring for current output DAC, stereo, single ended, 1mA full scale current, ~2.5V reference voltage

Known examples of a DAC’s requiring these settings is are Philips TDA1543A and TDA1545A (with modification as per Datasheet Note 5) and Burr Brown PCM67 & PCM69.


This type of DAC requires the following jumper settings:



The input connections should follow the Scheme shown underneath:



All Ground connections must be made to the DAC’s Analogue Ground Pin. All Vcom connections from the Universal Tube Output Stage must be made to the “Reference Voltage (Vref)” or “Common Mode Voltage (Vcom)” Pin(s) on the DAC.
