aSC7512
DC Electrical Characteristics
5
The following specifications apply for VDD = 3.3V, and all analog input source impedance Rs = 50Ω unless otherwise
specified in conditions. Boldface limits apply for TA = TJ over TMIN to 85°C; all other limits TA = TJ = 25°C. TA is the
ambient temperature of the aSC7512; TJ is the junction temperature of aSC7512; TD is the remote thermal diode junction
temperature. Specifications subject to change without notice
