ABSTRACT:
The A-to-D converter 300 has an output buffer 320 with fourteen drivers each the same as driver 4100. Driver 4100 includes bipolar pull up pull down transistors 4102, 4103. Those transistors are both coupled to an output. Pull up transistor 4102 is coupled to a first reference voltage VDD; pull down transistor 4103 is coupled to a second or ground reference potential. A base drive circuit comprising a series connection between a resistor and a transistor 4121 to provide additional current to saturate the pull down transistor 4103 and thereby lower the collector-to-emitter voltage drop of transistor 4103 when transistor 4103 is turned on.
