AD5280BRU20 Frequently Asked Questions (FAQ)
-
The recommended power-up sequence is to apply VDD first, followed by VLOGIC, and then the digital inputs. This ensures proper device operation and prevents latch-up.
-
To ensure accurate voltage output, it is essential to use a high-precision voltage reference, such as the ADR421 or ADR4525, and to follow proper PCB layout and decoupling guidelines to minimize noise and voltage drops.
-
The AD5280BRU20 can drive up to 1000 pF of capacitive load. However, it is recommended to limit the capacitive load to 100 pF or less to ensure stable operation and minimize ringing.
-
Yes, the AD5280BRU20 can be used in a ratiometric configuration, where the output voltage is proportional to the supply voltage. This can be useful in applications where the supply voltage is variable or noisy.
-
The AD5280BRU20 can be programmed using a microcontroller through a 3-wire serial interface (SPI-compatible). The microcontroller sends a 16-bit command word to the AD5280BRU20, which then sets the output voltage accordingly.
