The TPA2001D1PW from Texas Instruments is a 1-W mono, filterless Class-D audio power amplifier. It utilizes TI's third-generation modulation technique for improved efficiency and signal-to-noise ratio (SNR).
This amplifier is designed to drive an 8-Ω speaker and operates with analog input. Key electrical specifications include a power stage supply voltage range of 2.5V to 5.5V and an analog supply voltage range of 2.5V to 5.5V. It offers a typical supply current of 4mA (no filter) and a low shutdown current of 0.05 µA.
The TPA2001D1PW features a THD+N of less than 0.1% at 1 kHz and a maximum of 0.2% THD+N at 1W into an 8-Ω load. It provides internal gain settings ranging from 6 dB to 23.5 dB and has a PSRR of -77 dB. The device operates within an ambient temperature range of -40°C to 85°C.
Packaged in a 16-pin TSSOP, the TPA2001D1PW is optimized for applications requiring compact size and high efficiency. Its filterless design simplifies the external circuitry, though system-level EMI shielding may be required. Integrated depop circuitry and short-circuit protection enhance its robustness.
The power stage and analog supply voltage range is 2.5V to 5.5V.
The TPA2001D1PW is available in a TSSOP (PW) package with an area of 32 mm² (5 mm × 6.4 mm).
The operating temperature range is -40°C to 85°C.
The output power is 1W into an 8Ω load (typical and maximum with THD+N<1%).
The maximum THD+N is 0.2% at 1 kHz into 8Ω load; typical is 0.1%.
The efficiency into 8Ω load ranges from 75% to 85%.
The gain is adjustable from 6 dB to 23.5 dB via internal settings.
