Notes
1.
All voltages are with respect to ground. Currents are positive into, negative out of specified terminal.
2.
All ground pins soldered onto a 20 cm2 PCB copper area with free air convection. T
a = +25°C.
3.
DIP package with external heatsink (Staver V7) and minimal copper area. Typical Rth
J-A = 27.5°C/W. Ta = +25°C.
4.
Not covered by final test program.
