ANC250

ANC250

ultra low noise scan voltage amplifier

The ANC250 is attocube’s high-end scan voltage amplifier for piezo scanning tubes and flexure scanners. All three input channels (-10 V…+10 V) generate differential scan voltages (x+, x-, y+, y-, z) up to 200 V. The ANC250 is notable for its ultra low noise specifications with an ouput noise of only 20 µV RMS.
