ADVANCE INFORMATION for pre-production products; subject to change without notice.
The channels of the ADS7028 can be configured as digital push-pull outputs supporting an output voltage up to AVDD. As shown in Figure 140, a push-pull output consists of two mirrored opposite bipolar transistors, Q1 and Q2. The device can both source and sink current because only one transistor is on at a time (either Q2 is on and pulls the output low, or Q1 is on and sets the output high). A push-pull configuration always drives the line opposed to an open-drain output where the line is left floating.
