Cautions
1. Do not short-circuit two or more output pins simultaneously.
2. If even one of the above parameters exceeds the absolute maximum ratings even momentarily, the quality of the product may be degraded. The absolute maximum ratings,therefore, specify the value exceeding which the product may be physically damaged. Use the product well within these ratings.
The specifications and conditions shown in DC Characteristics and AC characteristics are the ranges for normal operation and quality assurance of the product.
The ATJ2073 is a single-chip highly-integrated digital music system solution for devices such as dedicated audio players, PDAs, and cell phones. It includes an audio decoder with a high performance DSP with embedded RAM, ADPCM/AG record capabilities and USB interface for downloading music and uploading voice recordings. ATJ 2073 also provides an interface to S/PDIF audio data input, flash memory, LED/LCD, button and switch inputs, headphone, and microphone, and FM radio control. The ATJ2073's programmable architecture supports the MP3 and other digital audio standards. For devices like USB Flash Disk, the ATJ 2073 can act as a USB mass storage slave device to personal computer system. The ATJ 2073 has low power consumption to allow long battery life and an efficient flexible on-chip DC-DC converter that allows many different battery configurations, including 1xAA, 1xAAA, 2xAA,2xAAA.
