description

The 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, attenuation, deemphasis, 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.

^{^[dagger]} Available on tape and reel (LE) only.

This device contains circuits to protect its inputs and outputs against damage due to high static voltages or electrostatic fields; however, it is advised that precautions be taken to avoid application of any voltage higher than maximum-rated voltages to these high-impedance circuits. During storage or handling, the device leads should be shorted together or the device should be placed in conductive foam. In a circuit, unused inputs should always be connected to an appropriated logic voltage level, preferably either V_CC or ground.
