DC630A

DC630A demonstration circuit is a gm amplifier circuit using the LT®3469ETS8 and can drive an output up to 34V at 25mA from 5V or 12V supply. An internal boost converter of the LT3469 generates a supply voltage of up to 36V for the GM amplifier. This regulator switches at 1.5MHz, allowing the use of a tiny external inductor and capacitor. The 36V output capability of the switching regulator along with the high supply voltage of the amplifier combine to allow the wide output voltage range needed to drive a piezoceramic micro actuator.
