NJW1350
LOW VOLTAGE VIDEO AMPLIFIER WITH LPF
sGENERAL DESCRIPTION
The NJW1350 is a Low Voltage Video Amplifier with LPF circuit.
By the internal charge pump circuit, output capacitor is unnecessary.
The NJW1350 features low power and small package, and is
suitable for low power design on downsizing of portable video
system and system with video output.
Moreover, the following voltage gain variations are arranged.
- NJW1351(Gain=6dB)
- NJW1352(Gain=9dB)
- NJW1353(Gain=16dB)
