YDA168B

YDA168B D-4H3B MONO 3.3W Non-Clip DIGITAL AUDIO POWER AMPLIFIER „ General Description YDA168B (D-4H3B) is an integrated circuit with Max.3.3W (RL=4Ω)×1ch Class-D speaker amplifier. This speaker amplifier uses the filter-less method allowing a speaker to be directly connected to the output and features low-level distortion and noise characteristics. The speaker amplifier, having Yamaha original Power Limit Interlock Non-Clip function, controls Gain automatically and prevents output signals from being clipped at the supply voltage. In addition, this power limit function permits the maximum output to be arbitrarily specified to 100mW to 1000mW according to a speaker to use. Furthermore, this amplifier has the following functions: overcurrent and overtemperature protection functions, DC output protection function, under-voltage malfunction prevention function, as well as EMI noise and the pop noise reduction functions and High PSRR function. 2.5V～5.25V YDA168B (D-4H3B) 3.3W at 5V MONO Differential CTRL PL +8dB PWM Output Buffer +10dB Non-Clip + Power Limit Power-Down Control Circuit Protection BTL 4Ω～ YDA168B Simplified Diagram YDA168B CATALOG CATALOG No.: LSI-4DA168B20 2010.9 „ Features ・Supply Voltage ・Input ・Output VDD 2.5V to 5.25V Mono (Differential)×1 Speaker ( Class-D, BTL) YDA168B ・Maximum Output 3.3 W×1ch 0.93 W×1ch 1.00 W×1ch 0.75 W×1ch ・Maximum Output 2.4 W×1ch (Non-Clip) 0.70W×1ch ・Distortion (THD+N) 0.045 % (VDD = 5.0 V, RL = 4 Ω, THD+N = 10 %,...
