We developed an eight-channel low-noise analog front-end application specific integrated circuit (ASIC), designated "KW01", for solid-state radiation detectors. Each channel consists of a charge-sensitive amplifier, band-pass filters, a comparator, and a sample-and-hold circuit. To evaluate its noise performance, we designed a front-end carrier board for mounting the ASIC. By injecting test pulses, we confirmed that the equivalent noise level reaches $110\pm 1.0$ e- (rms) at $-20$ °C. The ASIC was also combined with a Schottky CdTe diode detector for spectral evaluation. As a result, a gamma-ray spectrum of the radioactive source 241Am was obtained with good energy resolutions of 2.43 keV (FWHM) for 59.5 keV gamma rays and 2.26 keV (FWHM) for 17.5 keV gamma rays at $-20$ °C.
