NF CA-261F2/CA-206L2 CA系列低噪声差分放大器

产品型号：CA-261F2/CA-206L2 原产地：日本

所属类别：精密差分放大器

产品简介：

CA-461F2 is a low noise differential amplifier which is realized input referred noise voltage density 1.5nV/√Hz and voltage gain 100 times. The CA-461F2 is not only realized low noise but also excellent DC characteristics (0.3µV/ºC) and frequency response (DC to 200kHz) by using low noise circuit of negative feedback technology. Low noise characteristics is performed low signal source impedance(less than 500 ohm). High precision signal processing and high density mounting are possible for using 20 pin single-inline package which has 6 surface strict shield
