aSC7621
DC Electrical Characteristics5
The following specifications apply for VDD = 3.0V to 3.6V, and all analog input source impedance Rs = 50Ω unless
otherwise specified in conditions. Boldface limits apply for TA = TJ over TMIN to TMAX; all other limits TA = TJ = 25°C. TA
is the ambient temperature of the aSC7621; TJ is the junction temperature of aSC7621; TD is the remote thermal diode
junction temperature. Specifications subject to change without notice
