General Description
The APA2071 is a monolithic integrated circuit, which
provides precise DC volume control, and a stereo
bridged audio power amplifiers capable of producing
2.6W (2W) into 4Ω with less than 10% (1.0%) THD+N.
The attenuator range of the volume control in APA2071 is
from 18dB (V
VOLUME
=0V) to -80dB (V
VOLUME
=3.54V) with 32
steps. The advantage of internal gain setting can be less
components and PCB area. Both the depop circuitry and
the thermal shutdown protection circuitry are integrated
in the APA2071, that reduce pops and clicks noise dur-
ing power up or shutdown mode operation. It also im-
proves the power off pop noise and protects the chip be-
ing destroyed by over temperature and short current
failure. To simplify the audio system design, the APA2071
combines a stereo bridge-tied load (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.
Applications
