描述 Description

OT8000 is a highly-integrated USB digital audio bridging controller with flexible features for Apple/Android digital audio docking systems. It has 2 channel DAC/ADC outputs with headphone amplifier that supports 16-bit resolution and 96KHz, 48 KHz, 44.1 KHz, 32 KHz, 22.05 KHz, 16 KHz, 11.025 KHz, 8 KHz sampling rates. In addition, it also supports digital audio input and output via I2S interface.\r
\r
The OT8000 contains many GPIOs, rich bus/interfaces, RTC, SAR ADC, UART, I2C, SPI. Only a 32.768 KHz crystal is needed in the system and the PLLs of OT8000 can generate clocks for various applications.\r
\r
OT8000 is available for 80 pins LQFP (10x10mm) and 128 pins LQFP (14x14mm) package.
