SOIC-28, øJA = 58.6ºC/W
SSOP-28, øJA = 67.1ºC/W
TSSOP-28, øJA = 83.6ºC/W
QFN-32, øJA = 22.4ºC/W
These are stress ratings only and functional
operation of the device at these ratings or
any other above those indicated in the opera-
tion sections of the specifications below is not
implied. Exposure to absolute maximum rating
conditions for extended periods of time may
affect reliability.
NOTE 1: V+ and V- can have maximum
magnitudes of 7V, but their absolute difference
cannot exceed 13V.
ELECTRICAL CHARACTERISTICS
Unless otherwise noted VCC = +3.0V to +5.5V, TAMB = TMIN to TMAX, C1–C4 = 0.1μF.
Typical values are at TAMB = +25°C, VCC = 3.3V.
