Study of the Temperature Stability of the High-Voltage DAC AD5535 for Powering Silicon Photomultipiers
In this paper we present the results of a study of a high-voltage 32-channel DAC AD5535 for powering silicon photomultipliers. Built-in high-voltage buffer amplifiers allow output voltage regulation in the range of up to 200 V which provides application for a broad SiPM types including their serial connection. The significant output current of 500 μA/ch allows biasing the SiPM arrays and assemblies. The documentation indicates a significant temperature dependence of \(\sim ~200~\) ppm/C which limits the use of DAC for SiPM powering. This work demonstrates the excellent temperature stability of the chip. Still since the manufacturer does not guarantee this an express method of channel-by-channel measurement of temperature dependence has been developed for a mass use of the AD5535 DAC
