The device provides high-resolution signal conversion. This device consists of two identical synchronous conversion paths for left and right audio channels. Other overhead functions provide on-chip timing and control. Additional features include muting, attenuation, de-emphasis, and zero-data detection. Control words (16-bit) from a host controller or processor implement these functions. The TMS57014A is characterized for operation from 0°C to 70°C. AVAILABLE OPTION† PACKAGE TA SMALL OUTLINE (DWB)...
