DATASHEET ISL4089 FN6192 Rev 1.00 DC-Restored Video Amplifier June 28, 2006 The ISL4089 is complete DC-restored monolithic video Features amplifier sub-system. It contains a high performance video Complete video level DC-restoration system amplifier and a nulling, sample-and-hold amplifier designed to establish a programmable DC output level. 0.03% differential gain and 0.05 differential phase accuracy When the HOLD logic input 0 is applied the DC restore 300MHz -3dB small signal bandwidth at A = 1 function is active. The sample-and-hold amplifier loop is V closed and used to null the DC offset of the video amplifier. 150MHz -3dB small signal bandwidth at A = 2 V This can occur during sync, or, at any time that a black level 300V/s Slew Rate is expected. When the HOLD input 1 is applied, the correcting voltage is stored on the video amplifiers input 0.1dB flatness to 80MHz coupling capacitor. This condition must be true during active +5V single supply operation video. The restored DC voltage level can be adjusted using an external reference voltage applied to the V pin. TTL/CMOS compatible hold signal REF Pb-free plus anneal available (RoHS compliant) The device operates from a single +5V supply and is ideal for +5V only systems when used with a sync separator, such Applications as the EL1883. Input amplifier in video equipment The ISL4089 is intended to directly replace the EL4089 only in certain applications. This direct replacement requires that DC-restoration amplifier in video mixers the single positive supply is no higher than +5.5V and that no part of the clamped output goes below ground. The NC on Related Documents pin 6 is not internally connected, so it can be connected to AN1261: ISL4089EVAL1 Users Guide the -5V pin in existing EL4089 applications. AN1089: EL4089 and EL4390 DC-Restored Video The ISL4089 is specified for operation over -40C to +85C Amplifier temperature range. Ordering Information Pinout PART TAPE & PKG.
