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, 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 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
VCC or ground.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of Texas Instruments
standard warranty. Production processing does not necessarily include
testing of all parameters.
