  • Page 3 The headers J2 and P2 are the connectors provided to allow the control signals and data required to interface a host processor or waveform generator to the DAC8801/11EVM using a custom built cable. The MDAC output can be monitored through the J4 header connector. In addition, the MDAC output (via U5) can be connected to the output operational amplifier, U4A, by using a jumper across pins 5 and 6 or pins 7 and 8 of J4 header.
  • Page 4: Pcb Design And Performance

    PCB Layout The DAC8801/11EVM is designed to demonstrate the performance quality of the installed MDAC device under test, as specified in the data sheet. Careful analysis of the EVM physical restrictions and factors that contributes to the EVM performance degradation is the key to a successful design implementation.
