Abstract
A latch includes a current source, an input amplifier, and a latch output circuit. The current source is configured to output a current based on a voltage source. The input amplifier is configured to receive a differential analog input signal including a first differential input and a second differential input and selectively provide the current based on the first differential input and the second differential input. A latch output circuit is configured to selectively output a differential digital output signal including a first differential output and a second differential output. The latch output circuit includes an over voltage protection circuit configured to receive the current output from the input amplifier, receive the voltage source limit, and output a modified differential digital output signal based on a comparison between a voltage corresponding to each of the first differential output and the second differential output and the voltage source limit.
