ISL59837

200MHz Single Supply Video Driver With Charge Pump and Power Down

Product Status: Mass Production

OVERVIEW

The ISL59837 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 ISL59837 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. The charge pump and amplifiers can be placed in a power down mode, consuming less than 1mA of current.

KEY FEATURES

  • Triple single-supply buffer
  • Generates negative rail from from single +3.3V supply
  • No output DC blocking capacitor needed

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