Visão Geral
Description
- Output Power: Up to 3W (at 5V, 4Ω load)
- Efficiency: >85% (Class D topology)
- Low Quiescent Current: ~3mA (shutdown mode: <1μA)
- Wide Voltage Range: 2.5V–5.5V (ideal for Li-ion/AA batteries)
- Built-in Protection: Short-circuit, over-temperature, and under-voltage lockout (UVLO)
It requires minimal external components, supports differential inputs, and offers excellent noise suppression. The HT6872 is commonly used in space-constrained designs due to its compact package (e.g., SOP-8).
For detailed specs, refer to the datasheet.
Equivalent
- TPA2016 (Texas Instruments)
- PAM8403 (Diodes Incorporated)
- MAX98357 (Maxim Integrated)
- NS4150 (Nuvoton)
These chips offer similar power output (2-3W) and efficiency for small speakers. Check datasheets for exact voltage, THD, and package compatibility.
Features
- Output Power: Up to 7W (4Ω, 5V) or 5W (8Ω, 5V).
- Efficiency: >90% (Class D operation).
- Low Noise: Improved PWM modulation reduces switching noise.
- Wide Voltage Range: 2.5V–5.5V (single supply).
- Low THD+N: <1% (1W, 4Ω).
- Standby Mode: Ultra-low quiescent current (<1μA).
- Protections: Over-current, thermal shutdown, and under-voltage lockout (UVLO).
- Small Package: Available in SOP-8 or ESOP-8.
Ideal for portable devices, Bluetooth speakers, and battery-powered audio applications.
Pinout
- Power Supply (VDD, PVDD, GND): Operates at 2.5V–5.5V (VDD) and 2.5V–7V (PVDD).
- Audio Input (INP, INN): Differential input for audio signal.
- Output (OUTP, OUTN): Bridge-tied load (BTL) output for driving speakers.
- Shutdown (SD): Active-low control to enable/disable the chip.
- Gain Setting (GAIN0, GAIN1): Configures gain (6dB, 12dB, 18dB, or 24dB).
- Bypass (BYP): Connects to a decoupling capacitor for internal reference.
Designed for low EMI and high efficiency, it delivers up to 3W output (at 5V, 4Ω load).
