描述
The ISL59833 is a revolutionary device that allows true singlesupply operation of video amplifiers. Designed for systems requiring output swing below ground but lacking a negative power supply, the ISL59833 generates the required negative rail internally from a +3. 3V power supply. This allows for DC-accurate coupling of video onto a 75Ω double-terminated line. The buffers have an integrated 6dB, eliminating the need for external gain-setting resistors. An external reference voltage can be applied to the REF pin to shift the analog video level down by the desired amount.

- 50MHz 0.1dB bandwidth
- Fixed gain of 2 output buffer
- Amplifier enable/disable function control
- Outputs are high impedance in power-down mode
- Pb-free plus anneal available (RoHS compliant)
