UDA1334ATS/N2,112

The UDA1334ATS/N2,112 is a low power audio Digital-to-Analogue Converter with PLL. The extremely low power consumption and low voltage requirements make the device eminently suitable for use in low-voltage low-power portable digital audio equipment which incorporates a playback function. The converter supports the I²S-bus data format with word lengths of up to 24-bit and the LSB-justified serial data format with word lengths of 16, 20 and 24 bits. The converter has basic features such as de-emphasis (44.1kHz sampling frequency, only supported in audio mode) and mute.

• On-board PLL to generate the internal system clock
• Operates as an asynchronous DAC, regenerating the internal clock from the WS signal
• Generates audio related system clock (output) based on 32, 48 or 96kHz sampling frequency
• Integrated digital filter plus
• Supports sample frequencies from 16 to 100kHz in asynchronous DAC mode
• No analogue post filtering required for DAC
