ELECTRICAL CHARACTERISTICS (Test Condition, unless otherwise specified: VCC = 5V, VDD = 3.3V,

VB- = -48V, AGND = BGND, Tamb = 25°C).

Note: the limits below listed are guaranteed with the specified test condition and in the 0 to 70°C tem-

perature range. Performance over -40 to +85°C range are guaranteed by product characterisation.
