TPA2028D1's output power 43 percent higher than competition to improve
volume and clarity in portable devices
DALLAS, May 17 /PRNewswire/ -- Texas Instruments Incorporated (TI) (NYSE: TXN)
today introduced a 3.2-W per channel stereo Class-D amplifier and a 3-W, mono
Class-D amplifier, both with fast gain ramp SmartGain(TM) automatic gain control
(AGC) and programmable dynamic range compression (DRC). To achieve louder volume
from the speaker without increasing the peak voltage, the TPA2028D1 and
TPA2026D2 incorporate DRC to boost soft volumes automatically, allowing
designers to compress the dynamic range of the audio to match the dynamic range
of the speaker. Designers of cell phones, notebook PCs and portable DVD players
can benefit from this cost-effective, smaller amplifier that extends battery
life while improving volume and clarity. To order samples or for more
information, visit: www.ti.com/tpa2028d1-pr.
Key features and benefits of the TPA2028D1 and TPA2026D2
-- The devices have higher output power than the leading competition,
yielding louder volume.
o TPA2028D1 drives 3 W/channel into 4 Ohms at 5 V for 43 percent higher
output power.
o TPA2026D2 drives 3.2 W/channel into 4 Ohms at 5 V for 52 percent
higher output power 2x reduction in the quiescent current extends
battery life.
-- 10x reduction in offset voltage, significantly lowers pop-noise for
clearer audio.
-- Programmable SmartGain DRC with selectable compression ratios for up to
30-dB gain significantly enhances the loudness without increasing the
peak voltage.
Availability and pricing
The TPA2028D1 is available now in a 1.63-mm x 1.63-mm, 0.5-mm pitch, 9-ball WCSP
and is priced at $0.90 in 1,000-unit quantities. The TPA2026D2 is available now
in a 2.2-mm x 2.2-mm, 0.5-mm pitch, 16-ball WCSP and is priced at $1.30 in
1,000-unit quantities.
