The TPA2000D4 is a 2-W stereo bridge-tied-load (BTL) class-D amplifier from Texas Instruments, capable of driving speakers with impedances as low as 4 Ω. It utilizes TI’s second-generation modulation technique, enhancing efficiency and SNR, and allowing for filterless operation. This design is particularly suitable for notebook PCs, extending battery life through high efficiency, and for USB-powered speakers where it can deliver higher output power without tripping overcurrent protection.
In addition to the main class-D amplifier, the TPA2000D4 includes a stereo single-ended (SE) class-AB headphone amplifier. The gain for both amplifiers can be configured. The device operates over an ambient temperature range of -40°C to 85°C and features a low supply current of 9 mA typical at 5 V. Shutdown control is available, with a typical shutdown current of less than 0.05 µA.
The TPA2000D4 is available in a 32-pin thermally-enhanced TSSOP (DAP) package. This packaging allows for significant thermal performance, enabling stereo 2-W continuous output power levels into 4-Ω loads with proper PCB thermal design. The amplifier includes depop circuitry to minimize turn-on pops during power-up or mode switching.
The TPA2000D4 delivers 2W per channel into a 4Ω load from a 5V supply.
The typical supply current is 9mA at 5V.
The shutdown current is less than 0.05µA.
The operating temperature range is -40°C to 85°C.
The gain can be set to 6, 12, 18, or 23.5dB.
The headphone amplifier provides 90mW output.
The TPA2000D4 is available in a TSSOP (DAP) surface-mount package.
