ABSTRACT:
A method (701-717) and apparatus for providing a driver system requiring a reduced number of amplifier circuits. Load driving circuitry (205) is configured to include a single loop amplifier (401) for sequentially receiving multiplexed signals representative of the parameter values and effecting the output of such signals to corresponding loads. Sample-and-hold circuitry is coupled between the output of the loop amplifier (401) and load circuitry within the driver circuits (409, 429, 435) in an arrangement such that only one loop amplifier (401) is required in a multiplexed multi-input system.
