INTEGRATED CIRCUITS DATA SHEET UDA1330ATS Low-cost stereo filter DAC Product specification 2001 Feb 02 Supersedes data of 2000 April 18NXP Semiconductors Product specification Low-cost stereo filter DAC UDA1330ATS FEATURES General Low power consumption Power supply voltage from 2.7 to 5.5 V Selectable control via L3 microcontroller interface or via static pin control System clock frequencies of 256f , 384f and 512f s s s selectable via L3 interface or 256f and 384f via static s s pin control APPLICATIONS Supports sampling frequencies (f ) from 8to55kHz s PC audio applications Integrated digital filter plus non inverting Car radio applications. Digital-to-Analog Converter (DAC) No analog post filtering required for DAC GENERAL DESCRIPTION Slave mode only applications The UDA1330ATS is a single-chip stereo DAC employing Easy application bitstream conversion techniques. Small package size (SSOP16) 2 The UDA1330ATS supports the I S-bus data format with TTL tolerant input pads word lengths of up to 20 bits, the MSB-justified data format Pin and function compatible with the UDA1320ATS. with word lengths of up to 20 bits and the LSB-justified serial data format with word lengths of 16, 18 and 20 bits. Multiple format input interface The UDA1330ATS can be used in two modes: L3 mode or 2 L3 mode: I S-bus, MSB-justified or LSB-justified the static pin mode. 16, 18 and 20 bits format compatible In the L3 mode, all digital sound processing features must 2 Static pin mode: I S-bus and LSB-justified be controlled via the L3 interface, including the selection of 16, 18 and 20 bits format compatible the system clock setting. 1f input format data rate. s In the two static modes, the UDA1330ATS can be operated in the 256f and 384f system clock mode. s s DAC digital sound processing Muting, de-emphasis for 44.1 kHz and four digital input 2 Digital logarithmic volume control in L3 mode formats (I S-bus or LSB-justified 16, 18, and 20 bits) can be selected via static pins.
