The TPA2000D4DAP is a 2-W stereo bridge-tied-load (BTL) class-D audio amplifier from Texas Instruments, designed to drive speakers with impedances as low as 4 ohms. It utilizes TI's second-generation modulation technique, offering improved efficiency and SNR. This technique allows for direct connection to the speaker without an LC output filter, though system-level EMI shielding is required.
Ideal for notebook PCs and USB-powered speakers, the TPA2000D4DAP's high efficiency helps extend battery life and allows for higher output power from USB sources without tripping over-current protection. The device features an integrated Class-AB headphone amplifier with adjustable gain. The amplifier operates over a temperature range of -40°C to 85°C and is housed in a space-saving, thermally-enhanced PowerPAD™ HTSSOP package.
Key features include filterless operation, improved efficiency, and low supply current (9 mA typical at 5 V). It also has a shutdown control with very low typical current consumption (< 0.05 µA) and a TTL-compatible shutdown pin.
