Abstract

The present invention provides improved techniques for controlling current flow in an amplifier circuit. Specific embodiments provide steering of analog outputs of digital to analog converters in order to drive columns of an LCD display. Embodiments can provide a full range of voltage output to drive an LCD display without necessitating a full range amplifier configuration. Further, many specific embodiments can be realized in smaller space on an IC chip than in conventional technologies.
