Q & A
- What is the operating supply voltage range of the NCV2561SQT1G?
The operating supply voltage range is from 2.7 V to 3.3 V.
- What is the quiescent current when the device is enabled?
The quiescent current when enabled is typically 6.0 mA to 9.0 mA.
- How much current can the NCV2561SQT1G output?
The device can output up to ±50 mA.
- What is the purpose of the SAG correction circuit?
The SAG correction circuit reduces the need for large coupling capacitors, helping to minimize field tilt effects on the video signal.
- Is the NCV2561SQT1G suitable for automotive applications?
- What is the maximum junction temperature of the NCV2561SQT1G?
The maximum junction temperature is 150°C.
- How does the integrated level shifter function?
The integrated level shifter avoids clipping of the sync signal at the output by shifting up the video signal by about 60 mV, ensuring the output signal is not clipped due to the lower rail limit.
- Can the NCV2561SQT1G be used in DC-coupled configurations?
- What is the ESD protection level of the NCV2561SQT1G?
The device has ESD protection up to 2 kV HBM.
- How does the enable pin function?
The enable pin allows the device to be enabled or disabled, with a high state enabling the device and a low state disabling it. When left open, the default state is high.
