General Description
APA2120/APA2121 is a monolithic integrated circuit, which pro-
vides precise DC volume control, and a stereo bridged
audio power amplifiers is capable of producing 2.7W(2.
0W) into 3Ω with less than 10% (1.0%)THD+N. The at-
tenuator range of the volume control in APA2120/1 is from
20dB (DC_Vol=0V) to -80dB (DC_Vol=3.54V) with 32
steps. The advantage of internal gain setting can be less
components and PCB area. Both of the depop circuitry
and the thermal shutdown protection circuitry are inte-
grated in APA2120/1 and reduce pops and clicks noise
during power up or shutdown mode operation. It also
improves the power off pop noise and protects the chip
from being destroyed by over temperature and short cur-
rent failure. To simplify the audio system design, APA2120/
1 combines a stereo bridge-tied loads (BTL) mode for
speaker drive and a stereo single-end (SE) mode for head-
phone drive into a single chip , where both modes are
easily switched by the SE/BTL input control pin signal.
Besides, the multiple input selection is used for portable
audio system.
