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 µ V RMS .
