ABSTRACT:
A bit switch is provided for use in a digital-to-analog converter for providing a bit current to a summing bus. A first differential pair of switching devices are responsive to a digital input signal and provide first and second output signals to a second differential pair of switching devices that provide the bit current. First and second drive circuits are coupled between the first and second differential pair of switching devices for respectively slowing down the voltage transition of the first and second output signals for reducing glitches in the bit current.
