LM6104 Quad Gray Scale Current Feedback Amplifier
June 1994
LM6104
Quad Gray Scale Current Feedback Amplifier
General Description
The LM6104 quad amplifier meets the requirements of battery operated liquid crystal displays by providing high speed
while maintaining low power consumption.
Combining this high speed with high integration, the
LM6104 conserves valuable board space in portable systems with a cost effective, surface mount quad package.
Built on National’s advanced high speed VIP
TM
(Vertically
Integrated PNP) process, the LM6104 current feedback architecture is easily compensated for speed and loading conditions. These features make the LM6104 ideal for buffering
grey levels in liquid crystal displays.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. DC and AC electrical specifications do not apply when operating
the device beyond its rated operating conditions. Operating ratings indicate conditions the device is intended to be functional, but device parameter specifications
may not be guaranteed under the conditions.
