4 ELECTRICAL CHARACTERISTICS
Test conditions: Vpos = 6.0V, AGND = BGND, Normal Polarity, Tamb = 25°C.
External components as listed in the "Typical Values" column of EXTERNAL COMPONENTS Table.
Note: Testing of all parameter is performed at 25°C. Characterisation as well as design rules used allow
correlation of tested performances at other temperatures. All parameters listed here are met in the oper-
ating range: -40 to +85°C.
