The DACxx68 Evaluation Module is an evaluation board containing all the necessary components to
evaluate the eight-channel DAC7568, DAC8168, or DAC8568 series of high-performance digital-to-analog
converters from Texas Instruments. The EVM is designed so that a single printed-circuit board (PCB)
supports the entire family of high-speed, 12- to 16-bit serial DACs. The EVM is provided with Grade C
devices which reset to zero and have a full-scale output range of 0 V to 5 V.
The modular EVM form factor allows for direct evaluation of the DAC's performance and operating
characteristics. This EVM is compatible with the 5-6K Interface Board (SLAU104) from Texas Instruments
as well as the HPA-MCU Interface Board (SLAU106).

The analog output from the EVM is applied directly to J2 (top or bottom side) pins 2-16 (even). The DACxx68EVM does not provide any additional filtering or buffering of the output voltage, so that the user may evaluate the converter’s low-glitch output performance.

EVM is to place a shunt jumper between pins 1-2 of JP6. This allows the Timer Output (TOUT) signal from DSP host systems to be used as the LDAC input to the DAC. This signal originates from J1.17.
