Texas Instruments TPA2001D1 1-W Mono Class-D Audio Amplifier TPA2001D1PWG4

The TPA2001D1 is a 1-W mono Class-D audio amplifier designed for driving an 8-,Ѷ speaker. It features a filterless design that allows direct connection to the speaker, enhancing efficiency and reducing electromagnetic interference. The amplifier operates with a low supply current of 4 mA without a filter and 7.5 mA with a filter, while achieving a maximum efficiency of 75-85%. It has a total harmonic distortion plus noise (THD+N) of less than 0.2% at 1 W output, ensuring high audio quality. The device includes integrated depop circuitry to minimize turn-on noise and offers short-circuit protection. Gain can be adjusted through two input terminals, allowing configurations of 6, 12, 18, and 23.5 dB. The TPA2001D1 operates over a temperature range of -40¬8C to 85¬8C and is housed in a 16-pin TSSOP package, making it suitable for various applications where space and efficiency are critical.
