Product Description
A wide range of audio ICs also Microelectronics Technology program of free design sound advantages of supply amplifier, radio, storage, boost, etc. ·
AC209 Series USB HOST program profiles
► sound quality is excellent
SNR up to 88-92dB, using the 24Bit DAC technology, the sound is soft and delicate, compared with
Several other speakers on the market program, the intensity and purity in the bass have increased dramatically,
Low dive and rebound velocity were increased, crossover design by careful tuning to achieve good frequency
Rate of reaction, each scale parsing is accurate, clear, sweet vocals, empty of sense.
Simple ► circuit (multiple circuit chip)
1 headphone amplifier directly promote the headphones, the output amplitude is close to 3V;
Internal integrated LED / LCD screen drive, no external resistor;
Internal integrated infrared decoder, using the infrared diodes replace the infrared receiver;
4 built-in Mute circuits, no external transistor;
5 built-in low power detection, reset circuit, the external is very simple;
Large current drive IO port, you can directly control the backlight brightness, without the transistor;
7 built-in crystal compensation, you can use 32 crystal;
8 built-effectiveness of RTC
9 eliminates the need for the 24C02
And so substantially reduce costs, improve the yield of the product line.
