NJW1350 LOW VOLTAGE VIDEO AMPLIFIER WITH LPF QGENERAL 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) QPACKAGE OUTLINE NJW1350RB1 MSOP8(TVSP8) NJW1350KK1 QFEATURES O Operating Voltage 2.5 to 3.45V O Output coupling capacitor-less O 12dB amplifier O Internal 75Ω Driver Circuit (2-system drive) -38dB at 19MHz typ O 6th order LPF O Power Save Circuit O Bi-CMOS Technology O Package Outline MSOP8(TVSP8)*, SON10 *MEET JEDEC MO-187-DA / THIN TYPE QPIN CONFIGURATION NJW1350RB1(TVSP8) 1 8 2 7 3 6 4 5 1: CP1 2: V+ 3: VIN 4: Power Save 5: VOUT 6: GND 7: V8: CP2 NJW1350KK1(SON10) 1 10 2 9 3 8 4 7 5 6 QBLOCK DIAGRAM 1: CP1 2: V+2 3: V+1 4: VIN 5: Power Save 6: VOUT 7 GND1 8: GND2 9: V10: CP2 V+1 V+2 12dB 6th LPF VIN V- 75Ω Driver VOUT POWER SAVE Charge Pump CP1 CP2 GND1 GND2 (NOTE) TVSP8: V+1 and V+2 are the same pins, and GND1 and GND2 are the same pins.
