CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
NOTE:
1.
θJA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. θJC, the
“case temp” is measured at the center of the exposed metal pad on the package underside. See Tech Brief TB379.
2. For
θJC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications - 5V Supply
Test Conditions: VDD = +5V, GND = 0V, VINH = 2.4V, VINL = 0.8V, SD = MIX = INS = HD =
VINL, CREF = 1F, RL is terminated between SPK+ and SPK- for BTL driver and between
Hp_ and GND for SE drivers, Unless Otherwise Specified (Note 3).
