Philips Semiconductors Product speciﬁcation

1 to 4 W audio power ampliﬁer TDA1015

RATINGS

Limiting values in accordance with Absolute Maximum System (IEC 134)

HEATSINK DESIGN

Assume VP = 12 V; RL = 4 Ω; Tamb = 45 °C maximum.

The maximum sine-wave dissipation is 1,8 W.

Rth j-a =R

th j-tab +R

th tab-h +R

th h-a = = 58 K/W.

Where Rth j-a of the package is 45 K/W, so no external heatsink is required.

Supply voltage VPmax. 18 V

Peak output current IOM max. 2,5 A

Total power dissipation see derating curve Fig.2

Storage temperature Tstg −55 to + 150 °C

Operating ambient temperature Tamb −25 to + 150 °C

A.C. short-circuit duration of load

during sine-wave drive; VP = 12 V tsc max. 100 hours
