Switchable voltage follower and bridge driver using the same |
摘要 |
A switchable voltage follower and a bridge driver that utilizes the voltage follower. The voltage follower has an output transistor pair, three switching devices and an operational amplifier. Each of the switching devices is controlled by a polarity terminal for switching the circuit to be a pull-up voltage follower or a pull-down voltage follower. The bridge driver is formed by two switchable voltage followers to provide a bridge push-pull driving capability by driving the two switchable voltage followers alternately.
