General DesCMiption
The SC2038 is a dual bridge-connected audio
power amplifier which, when connected to a 5V
supply, will deliver 2.2W to a 4Ω load (Note 1) or
2.5W to a 3Ω load (Note 2) with less than 1.0%
THD+N. In addition, the headphone input pin allows
the amplifiers to operate in single-ended mode
when driving stereo headphones. To simplify audio
system design, the SC2038 combines dual bridge
speaker amplifiers and stereo headphone amplifiers
on one chip. The SC2038 features an externally
controlled, low-power consumption shutdown mode,
a stereo headphone amplifier mode, and thermal
shutdown protection. It also utilizes circuitry to
reduce clicks and popsduring device turn-on.
