DC2443A

DC2443A demonstration circuit is a configurable high voltage amplifier featuring the LT®6375. This demo board translates a high common mode signal to an output related to a low voltage reference level. The demo circuit is equipped with jumpers to facilitate setting the pin-strapped internal divider ratio configuration. The LT6375 is unique in that it may be powered from a low voltage (down to 3.3V) while it accepts signals well outside the supply range. This device is also unusual in that it can operate with high supply voltages (up to 50V). Connection points are provided to wire the amplifier in other configurations besides the simple translator.
