TPA2028D1

SLOS660C –JANUARY 2010–REVISED OCTOBER 2015
TPA2028D1 3-W Mono Class-D Audio Amplifier With Fast Gain Ramp SmartGain™
AGC/DRC Features 3 Description

The TPA2028D1 deviceisa mono, filter-free Class-D Fast AGC Start-up Time:5 ms audio power amplifier with volume control, fast gain• Pinout Compatible with TPA2018D1 ramp SmartGain™, dynamic range compression• Filter-Free Class-D Architecture (DRC), and automatic gain control (AGC).It is
availableina 1.63 mm× 1.63 mm wafer chip-scale• 3W Into4Ωat5V (10% THD+N) package (DSBGA).• 880 mW Into8Ωat 3.6V (10% THD+N)
The DRC/AGC functionin the TPA2028D1 deviceis• Power Supply Range: 2.5Vto 5.5V programmable througha digitalI2C interface. The• Flexible Operation With/WithoutI2 C™ DRC/AGC function canbe configuredto automatically• Programmable DRC/AGC Parameters prevent distortionof the audio signal and enhance
quiet passages that are normally not heard. The• DigitalI2 C™ Volume Control
DRC/AGC can also be configured to protect the• Selectable Gain from –28 dBto 30 dBin 1-dB speaker from damage at high power levels andSteps (when compressionis used) compress the dynamic rangeof musictofit within the• Selectable Attack, Release and Hold Times dynamic range of the speaker. The gain can be
selected from –28 dBto +30 dBin 1-dB steps. The• 4 Selectable Compression Ratios
TPA2028D1is capableof driving3Wat5V intoa• Low Supply Current: 1.8 mA 4-Ω loador 880 mWat 3.6V into an 8-Ω load. The• Low Shutdown Current: 0.2 μA device features hardware and software shutdown High PSRR:80 dB controls and also provides thermal and short-circuit
protection. The TPA2028D1 hasa faster AGC gain• AGC Enable/Disable Function ramp during start-up than TPA2018D1.• Limiter Enable/Disable Function additionto these features,a fast start-up time and• Short-Circuit and Thermal Protection small package size make the TPA2028D1 an ideal• Space-Saving Package choice for cellular handsets, PDAs and other portable– 1.63 mm× 1.63 mm Nano-Free™ DSBGA applications.
