Key Features

The PCM1742KE/2K is a high-performance stereo DAC designed for premium audio applications. It uses an enhanced multilevel delta-sigma architecture to achieve outstanding dynamic performance and reduce clock jitter. This ensures accurate digital-to-analog conversion with minimal distortion. The device supports a wide range of sampling frequencies, from 5 kHz to 200 kHz, making it adaptable for many audio systems.

It accepts 16-, 18-, 20-, and 24-bit audio data in standard, I²S, and left-justified formats. Additionally, its user-programmable functions include digital attenuation, de-emphasis, filter rolloff selection, soft mute, and zero flag detection. These features allow for greater flexibility in system design. The DAC operates on a dual-supply voltage of 5 V for analog and 3.3 V for digital, with 5 V tolerant digital inputs. Its compact 16-lead SSOP package makes it easy to integrate into space-limited designs.

Applications

AV receivers
Movie players
DVD add-on cards for high-end PCs
DVD audio players
HDTV receivers
Car audio systems
Other applications requiring 24-bit audio
