Key Features

  • Incorporates a two-channel microphone amp with auto level control (ALC), AD/DA converter, delay memory, and electronic volume controllers. Incorporates a 32-kHz sampling, 12-bit successive comparison AD/DA converter. Incorporates a delay memory (16-Kbit DRAM) which enables 128-ms (typ. ) delay. Microphone and echo levels are controlled by built-in volume controllers. They are controlled either by DC voltage or controlled in serial by the MCU. TC9455F/N: Supports I2C bus interface TC9488F/N:.
