REF5045IDR Frequently Asked Questions (FAQ)
-
The REF5045IDR should be placed close to the analog-to-digital converter (ADC) or digital-to-analog converter (DAC) it is supplying, and the input and output pins should be routed away from noisy digital signals. A ground plane under the device and a decoupling capacitor (e.g., 10nF) between the VIN pin and GND pin are also recommended.
-
To ensure stability and accuracy, the REF5045IDR should be operated within its specified temperature range (-40°C to 125°C). Additionally, the device should be soldered onto a PCB with a solid ground plane, and the input voltage should be well-regulated and within the recommended range (2.7V to 5.5V).
-
The typical start-up time for the REF5045IDR is around 10ms. This means that the device requires a minimum of 10ms to settle to its final output voltage after power-on. Engineers should ensure that their system's power-on sequence allows for this start-up time to ensure accurate voltage reference operation.
-
Yes, the REF5045IDR can be used as a voltage reference for multiple ADCs or DACs, but it's essential to ensure that the total output current drawn from the device does not exceed its maximum rating (10mA). Additionally, the output impedance of the REF5045IDR should be considered when designing the voltage reference distribution network.
-
During power-down or brownout conditions, the REF5045IDR's output voltage will decay to zero. When power is restored, the device will restart and settle to its final output voltage within the typical start-up time. Engineers should ensure that their system's power-down sequence does not cause the REF5045IDR to be in a state of rapid power cycling, which can affect its reliability.
