Data Sheet ADM3260 SPECIFICATIONS ELECTRICAL CHARACTERISTICS—5 V PRIMARY INPUT SUPPLY/5 V SECONDARY ISOLATED SUPPLY
Al typical specifications are at TA = 25°C, VIN = VISO = 5 V, VSEL resistor network RBOTTOM = 10 kΩ, RTOP = 30.9 kΩ. Minimum/maximum specifications apply over the entire recommended operation range which is 4.5 V ≤ VIN, VISO ≤ 5.5 V, and −40°C ≤ TA ≤ +105°C, unless otherwise noted. Switching specifications are tested with CL = 15 pF and CMOS signal levels, unless otherwise noted.
