7.2.1 Single Supply Operation

The LMH6572 uses mid-supply referenced circuits for the select and disable pins. In order to use the LMH6572 in single supply configuration, it is necessary to use a circuit similar to Figure 19. In this configuration the logical inputs are compatible with high breakdown open collector TTL, or open drain CMOS logic. In addition, the default logic state is reversed since there is a pull-up resistor on those pins. Single supply operation also requires the input to be biased to within the common mode input range of roughly ±2V from the mid-supply point.
