摘要： A circuit and method provides a low distortion buffer by using a resistive divider stage (18, 20) and a gain stage (12) whose gain is equal to the inverse of the attenuation ratio of the resistive divider to provide unity gain. Multiple inputs (14, 42, 44, . . . 46) to the buffer circuit are accommodated by an input switching network (30, 38). The gain error introduced by the resistance of the switching network (30, 38) is canceled by placing an equivalent network (60) in a feedback path of the gain stage. The preferred circuit topology is well-suited to low-voltage applications and provides a low-distortion output. Circuits for reducing power consumption (68, 70) and minimizing undesirable transients (72) are also provided.

The pullup driver has a drive control input, and an output for providing a pullup drive signal in a push-pull mode in response to receiving a first drive control signal on the drive control input, and in a current limited mode in response to receiving a second drive control signal on said drive control input. The pulldown driver has a drive control input, and an output for providing a pulldown drive signal in the push-pull mode in response to receiving a third drive control signal on the drive control input, and in the current limited mode in response to receiving a fourth drive control signal on the drive control input. The output stage provides a voltage on an output terminal in response to the pullup and pulldown drive signals.
