† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. Voltage values for maximum ratings are with respect to AGNDL and AGNDR respectively.
2. Voltage values for maximum ratings are with respect to DGND.
3. Voltage values for maximum ratings are with respect to XGND.
DescriptionThe TMS57014A is a stereo oversampled-sigma-delta digital-to-analog converter (DAC) designed for use in systems such as compact disks, digital audio tapes, multimedia, and video cassette recorders. 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 of the TMS57014A, 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.
