2.0 Quick Start
The diagram below shows how the
LM26LV is connected in a typical bench
test configuration.
Before applying power directly to the
LM26LV Evaluation Board, make sure that
the voltage is b1.6 VDC and +5.5
VDC. Also make sure that J3 and J4 are
jumpered for normal operation. Jumpering
J2 will put the LM26LV in TRIP TEST
mode, not for normal operation.
Apply power to the LM26LV evaluation
board. Measure the output voltage
connected between to output pin (J4) and
ground for the VTEMP Output voltage.
