Class D audio amplier
[8]
Machine Model (MM); Rs = 0 ; C = 200 pF; L = 0.75 H.
11. Thermal characteristics
[1]
Measured on a JEDEC high K-factor test board (standard EIA/JESO 51-7) in free air with natural convection.
[2]
Measured on a two-layer application board (55 mm
× 40 mm), 35 m copper, FR4 base material in free air with natural convection.
[3]
Measured on a three-layer application board (70 mm
× 50 mm), 35 m copper, FR4 base material in free air with natural convection.
[4]
Strongly dependent on where the measurement is taken on the package.
