Corrector Power Supplies with a DAC Resolution up to 24 Bits Based on 16 Bit DAC Devices {*}

At BESSY the standard 16 bit resolution of the corrector power supplies was insufficient for the continous orbit drift correction [1]. A new sophisticated design of the analog/digital I/O board [2] increases the resolution of the analog output up to 24 bits without suffering losses in the long term stability or the dynamic range of the correctors. This is achieved by a cost-efficient board design using standard 16 bit DAC devices in an range-overlapping fine/coarse architecture.
