LOW VOLTAGE VIDEO AMPLIFIER WITH LPF
QGENERAL DESCRIPTION QPACKAGE OUTLINE
The NJW1352 is a Low Voltage Video Amplifier with LPF circuit.
By the internal charge pump circuit, output capacitor is unnecessary.
The NJW1352 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 volt age gain variations are arranged.
- NJW1350(Gain=12dB)
- NJW1351(Gain=6dB)
- NJW1353(Gain=16dB)
QFEATURES
O Operating Voltage 2.5 to 3.45V
O Output coupling capacitor-less
O 9dB amplifier
O Internal 75Ω Driver Circuit (2-system drive)
O 6th order LPF -38dB at 19MHz typ
O Power Save Circuit
O Bi-CMOS Technology
O Package Outline MSOP8(TVSP8)*, SON10
*MEET JEDEC MO-187-DA / THIN TYPE
