Realizing large-scale ion-trap quantum computers requires independent and precise control of trap DC electrodes, whose number reaches roughly ten times the number of qubits, making high-density control systems a key challenge. In this work, we developed a DAC board with 50 channels of 16-bit, 3-MSPS, ±10-V arbitrary waveform output on a 170×100 mm board. By assembling these boards in a slot-insertion configuration, we aim to house 1000 channels in a 6U EIA 19-inch rack. In this talk, we report the performance evaluation of the prototype, including noise characteristics, slew rate, inter-channel jitter, and crosstalk, along with a comparison with conventional products.
