Electrical Characteristics (continued)

minimum and maximum specifications apply from TA = –50°C to +125°C; Typical specifications are at TA = 25°C;

all specifications are at AVDD = 2.7 V to 5.25 V, AVSS = 0 V, DVDD = IOVDD = 3.3 V, all gains, internal reference, internal

oscillator, all data rates, and global chop disabled (unless otherwise noted)
