Sleep Mode
The DAC5674 features a power-down mode that turns off the output current and reduces the supply current
to less than 5 mA over the supply range of 3 V to 3.6 V and temperature range. The power-down mode is
activated by applying a logic level 1 to the SLEEP pin (e.g., by connecting pin SLEEP to AVDD). An internal
pulldown circuit at node SLEEP ensures that the DAC5674 is enabled if the input is left disconnected. Power-up
and power-down activation times depend on the value of external capacitor at node EXTIO. For a nominal
capacitor value of 0.1-
F power-down takes less than 5 s, and power-up takes approximately 3 ms. With
external reference, power up takes 10
s; power down remains the same.
DAC5674 Evaluation Board
A combo EVM board is available for the DAC5674 digital-to-analog converter for evaluation. This board allows
the user the flexibility to operate the DAC5674 in various configurations. Possible output configurations include
transformer coupled, resistor terminated, inverting/noninverting and differential amplifier outputs. The digital
inputs are designed to interface with a TMS320 DSP SDK or to be driven directly from various pattern
generators with the onboard option to add a resistor network for proper load termination. See the DAC5674 EVM
User’s Guide (SWRU007) for more information.
