*Static-sensitive device. Unused devices must be stored in conductive
material. Protect devices from static discharge and static fields. Stresses
above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. These are stress ratings only and functional
operation of the device at these or any other conditions above those
indicated in the operational sections of the specifications is not implied.
Exposure to Absolute Maximum Rating Conditions for extended periods
may affect device reliability.
Notes:
1. Differential input voltage defined as (VIN+ – VIN–)
2. Resistance from INn+ to INn– or INn to GND.
DC ELECTRICAL CHARACTERISTICS: TA = 25°C and VDD = 2.7V, unless otherwise specified. Specifications
in Bold type apply over a temperature range of 0
°C to 85°C. VREF = 1.25V, Internal Clock Freq = 520kHz
