8MHz 5th Order Video Driver with 6dB Gain 8MHz single channel video driver
Features
Product Name: 8MHz 5th Order Video Driver with 6dB Gain 8MHz Single Channel Video Driver
Product model: SGM9121
Product Description:
The SGM9121 is single rail-to-rail 5th order output reconstruction filter with a -3dB bandwidth of 8MHz and a slew rate of 34.8V/μs. Operating from single power supply ranging from 3.0V to 5.5V and sinking an ultra-low 7mA quiescent current, the SGM9121 is ideally suited for low power, battery-operated applications.
SGM9121 employsan internal level shift circuit that avoids sync-pulse clipping and allows DC-coupled output. If AC-coupling is preferred, the SGM9121 offers a sag-correction feature that significantly reduces the size of the output coupling capacitor.
SGM9121 has a power-down disable feature that reduces the supply current to 0.72μA, dramatically reducing power consumption and prolonging battery life.
It is specified over the extended -40°С to +85°С temperature range
In order to make the output light load current of 50mA work in CCM mode with low noise, according to calculation, (12V-3.3V)*12V/3.3V/650000Hz/0.1A=0.00048H=480uH. How come it is dozens of uH?...
