TPA3001D 20瓦单声道D类音频功率放大器

FEATURES DESCRIPTION

23• 20 W Into 8-Ω Load From 18-V Supply (10% The TPA3001D1 (sometimes referred to as

THD+N) TPA3001) is a 20-W monaural bridge-tied load (BTL)

• Short-Circuit Protection (Short to VCC, Short to class-D audio power amplifier (class-D amp) with high

GND, Short Between Outputs) efficiency, eliminating the need for heat sinks. The

TPA3001D1 can drive 4-Ω or 8-Ω speakers with only

• Third-Generation Modulation Technique: a ferrite bead filter required to reduce EMI.

– Replaces Large LC Filter With Small,

Low-Cost Ferrite Bead Filter in Most The gain of the amplifier is controlled by two input

Applications terminals, GAIN1 and GAIN0. This allows the amplifier to be configured for a gain of 12, 18, 23.6,

– Improved Efficiency or 36 dB. The differential input stage provides high

– Improved SNR common-mode rejection and improved power-supply

• Low Supply Current: 8 mA Typ at 12 V rejection.

• Shutdown Control: < 1 mA Typ The amplifier also includes depop circuitry to reduce

• Space-Saving, Thermally-Enhanced the amount of pop at power-up and when cycling SHUTDOWN.

PowerPAD™ Packaging

The TPA3001D1 (TPA3001) is available in the 24-pin

APPLICATIONS thermally enhanced TSSOP package (PWP), which
