Description

The CAMAC 054 module is a six channel high resolution DAC. The DAC's used (Analog Devices DAC71-CSB-V) have 16 bits of resolution and are wired for unipolar operation. Each channel has a buffered out capable of driving a load capacitance of 300pf. Slew rate is limited to approximately .16V/uS. Zero and gain adjustments are provided for each channel. All outputs are set to zero upon power up or module clear.

Connection to this module is especially critical. Good cabling practices are mandatory - typically requiring shielded twisted pair cable. The signal from the 054 module should generally be received by a high quality differential amplifier. The module can source 10 mA at the Plus Full Scale Output.
