Overview
The UDA1341TS/N1,512 is a stereo audio CODEC designed for MiniDisc and portable applications. It integrates two ADCs and two DACs with bitstream conversion techniques. The device supports 20-bit resolution and operates at sample rates up to 48 kHz. Power supply ranges from 2.4 V to 3.6 V with typical operating currents of 12.5 mA for the ADC section. It features an L3-interface for microcontroller control and includes digital sound processing such as volume, tone control, and AGC. The component is housed in a 28-lead SSOP package.
Feature Summary
- Integrates fully analog front end with programmable gain amplifier and digital automatic gain control
- Supports multiple serial data formats including I2S-bus, MSB-justified, and LSB-justified configurations
- Includes digital sound processing features like dB-linear volume control, bass boost, treble, and de-emphasis
- Features hardware quick mute via static pin input and digital peak level detection
Applications
- MiniDisc home stereo systems
- Portable MD/CD boomboxes
- Notebook PCs with audio capabilities
- Digital video cameras requiring audio recording
Procurement Notes
This component is discontinued and no longer manufactured by NXP Semiconductors. Verification of availability requires checking distributor archives or secondary market sources. Designers should confirm lead compatibility if replacing on existing boards due to partial pin compatibility with UDA1340M and UDA1344TS.
Selection Notes
Select this part for low-power stereo audio conversion where digital signal processing is required within the codec. Ensure the system provides the necessary system clock frequencies (256fs, 384fs, or 512fs) as the device operates in slave mode only. Verify that the application supports the L3-interface protocol for configuration.
Part Context
The UDA1341TS belongs to the UDA134 family of economy audio CODECs. It shares partial pin compatibility with the UDA1340M and UDA1344TS, facilitating board upgrades. Unlike the UDA1340M, it adds digital mixing capabilities and a dedicated PGA with digital AGC for microphone inputs.

FAQ
Does the UDA1341TS support master clock generation?
No, the device supports slave mode only. System devices must provide the system clock.
What is the maximum word length supported by the data interface?
The interface supports word lengths up to 20 bits for I2S-bus and MSB-justified formats, and 16, 18, or 20 bits for LSB-justified formats.
How is the digital automatic gain control configured?
The digital AGC is controlled via the L3-interface, allowing users to set attack time, decay time, and output level parameters.
