УМЗЧ TPA4861D

Усилитель звуковой мощности , 1 Вт, AB, 1 канал, 2.7В до 5.5В, SOIC, 8 вывод(-ов)

The TPA4861D is a bridge-tied load (BTL) Audio power Amplifier capable of delivering 1W of continuous average power into a 8R load at 0.2% THD+N from a 5V power supply in voiceband frequencies (f<5kHz). A BTL configuration eliminates the need for external coupling capacitors on the output in most applications. Gain is externally configured by means of two resistors and does not require compensation for settings of 2 to 20. Features of the amplifier are a shutdown function for power-sensitive applications as well as internal thermal and short-circuit protection. The TPA4861 works seamlessly with TI's TPA4860 in stereo applications.

• No output coupling capacitors required
• Shutdown control (IDD=0.6µA)
• Uncompensated gains of 2 to 20 (BTL mode)
• Thermal and short-circuit protection
• 1W BTL output (5V, 0.11% THD+N)
• 3.3 and 5V Operation voltage
• 75dB PSRR
• Green product and no Sb/Br
