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 operating range: -40 to +85 °C.
