More Information
Summary:A line driver circuit is configured to provide a high spurious free dynamic range output and includes first and second output transistors and a control circuit. The first output transistor is controllable to pull an output node to a logic high state, and the second output transistor is controllable to pull the output node to a logic low state. The first control circuit is connected to a control input of the first output transistor and configured to establish a control signal at the control input of the first output transistor while the second output transistor is in a low impedance operating state to reduce an imbalance in turn-on delay between the first output transistor and the second output transistor.
