The file contains one executable and one dll file when unzipped as shown below. Please use appropriate file for an evaluation of the AD185X family DAC's. -------> 1852.exe, msvcrt.dll

Unzip these files using a WINZIP utility. Notice that, when unzipping the zip file, it will extract the two files mentioned above and they should both be saved in the same folder or directory.

AD1852 executable files provide the Graphical User Interface (GUI) implemented in the LabView package. Using this software utility, one can evaluate the DAC's serial data port (SPI) control for Serial Mode, Number of Bits (16,20,24), Volume, Mute, De-emphasis and Power down. The detailed description of the supported features is given below.

Interface between PC and Evaluation board can be controlled through three different parallel port addresses (LPT1, LPT2 and LPT3) on the pc.

3-wire Serial Input Data Format(I2s, Left-Justified, Right-Justified etc.) control through serial port.

Volume control of DAC stereo input signals through serial port. Both right and left channel can be controlled either independently or simultaneously. Simultaneous control is provided by linking both channels through a "LINK" button on the Graphical Interface.

Unmute/mute, Power down and De-emphasis control through serial port.

For AD1852 only, interpolation ratio and different De-emphasis filter control.
