UDA1342TS/N1,512

Overview

The UDA1342TS is a single-chip audio codec integrating four analog-to-digital converters and two digital-to-analog converters. It operates on a 2.7 V to 3.6 V supply with 5 V tolerant digital inputs. The device features a 24-bit data path, supports sample frequencies from 16 kHz to 110 kHz, and includes programmable gain amplifiers for ADC inputs. Key performance metrics include a typical signal-to-noise ratio of 100 dB for both ADC and DAC at 48 kHz sampling rates. It offers multiple control interfaces including L3-bus, I2C-bus, and static pin modes.

Feature Summary

• Integrates dual stereo ADCs with programmable gain amplifiers and double differential input configuration for enhanced sound quality.
• Includes digital signal processing capabilities such as volume control, mute, bass boost, treble, and de-emphasis controllable via microcontroller interface.
• Supports flexible digital audio interfaces including I2S-bus, MSB-justified, and LSB-justified formats with word lengths up to 24 bits.
• Features integrated decimation and interpolation filters along with a noise shaper to achieve high linearity and low distortion without requiring external analog post-filtering.

Applications

• MiniDisc home and portable applications
• Low-voltage low-power portable digital audio equipment
• Digital audio recording and playback systems

Procurement Notes

Verify component authenticity through authorized NXP distributors or certified suppliers. Confirm the part number matches UDA1342TS/N1,512 exactly. Check for RoHS compliance status and ensure the package integrity is intact upon receipt. Review the latest product specification for any superseding documentation or handling requirements before integration.

Selection Notes

Select this component for designs requiring a single-chip solution for stereo audio conversion with advanced digital filtering. Ensure the system clock frequency aligns with the supported ranges of 256fs, 384fs, 512fs, or 768fs. Verify that the host controller supports the required control interface, whether L3-bus, I2C-bus, or static pin mode, for proper configuration of gain and format settings.
