0,5 W audio power amplifier
TDA1015T
GENERAL DESCRIPTION
The TDA1015T is a low-cost audio amplifier which can deliver up to 0,5 W output power into a 16 W load impedance at
a supply voltage of 9 V. The amplifier is specially designed for portable applications such as radios and recorders.
The IC has a very low supply voltage requirement (3,6 V min.).
Features
·
High input impedance
·
Separated preamplifier and power amplifier
·
Limited noise behaviour at radio frequencies
·
Short-circuit protected
·
Miniature encapsulation.
