APA2030/2031
Stereo 2.6W Audio Amplifier(With Gain Control)
Features
General Description
• Low operating current with 6mA
• Improved depop circuitry to eliminate turn-on
transients in outputs
• High PSRR
• Internal gain control, eliminate external components.
• 2.6W per channel output power into 3Ω load at 5V,
BTL mode
• Multiple input modes allowable selected by HP
/LINE pin (APA2030)
• Two output modes allowable with BTL and SE
modes selected by SE/BTL pin (for APA2030 only)
• Low current consumption in shutdown mode (50µ
A)
• Short Circuit Protection
• TSSOP-24-P (APA2030) and TSSOP-20-P
(APA2031) with thermal pad package.
Applications
• NoteBook PC
• LCD Monitor
APA2030/1 is a monolithic integrated circuit, which
provides internal gain control, and a stereo bridged
audio power amplifiers capable of producing 2.6W
(1.9W) into 3Ω with less than 10% (1.0%) THD+N.
By control the two gain setting pins, Gain0 and Gain1,
The amplifier can provide 6dB, 10dB, 15.6dB, and
21.6dB gain settings. The advantage of internal gain
setting can be less components and PCB area. Both
of the depop circuitry and the thermal shutdown pro-
tection circuitry are integrated in APA2030/1, that
reduces pops and clicks noise during power up or
shutdown mode operation. It also improved the power
off pop noise and protects the chip from being de-
stroyed by over temperature and short current failure.
To simplify the audio system design APA2030 com-
bines a stereo bridge-tied loads (BTL) mode for
speaker drive and a stereo single-end (SE) mode for
headphone drive into a single chip, where both modes
are easily switched by the SE/BTL input control pin
signal. Besides the multiple input selections is used
for portable audio system. APA2031 eliminates both
input selection and single-end (SE) mode function to
simplifying the design and save the PCB space.
