TDA1010A
The TDA1010A is a monolithic integrated class-B audio amplifier circuit in a 9-lead single in-line (SIL) plastic package.
The device is primarily developed as a 6 W car radio amplifier for use with 4
W
and 2
W
load impedances. The wide supply
voltage range and the flexibility of the IC make it an attractive proposition for record players and tape recorders with
output powers up to 10 W.
Special features are:
·
single in-line (SIL) construction for easy mounting
·
separated preamplifier and power amplifier
·
high output power
·
low-cost external components
·
good ripple rejection
·
thermal protection
