KLauS4 is a 7-channel mixed-mode Silicon-Photomultiplier (SiPM charge readout ASIC dedicated to imaging calorimetry at a possible future linear collider, where one key aspect is the ultra-low power consumption of the readout electronics. The ASIC is designed to read out the SiPM charge information with high precision and over large dynamic range. Each channel consists of a low-noise front-end with two gain branches to deal with a large input signal range, and a 10/12-bit ADC to digitize the charge information; a common digital part for data storage and transmission is also implemented into this chip. Design of the ASIC, characterization measurements and beam-test results will be presented.
