Product details
Overview
UDA1342TS/N1,512 from NXP Semiconductors is a 24-bit stereo audio CODEC IC integrating dual stereo ADCs (4-channel single-ended analog inputs) and dual-channel DAC with digital signal processing, operating from 2.7–3.6 V supply, supporting 16–110 kHz sampling rates, and designed for portable MiniDisc recording/playback systems requiring low-power, high-SNR audio conversion.
For engineers reviewing the UDA1342TS/N1,512 datasheet, UDA1342TS/N1,512 pinout, UDA1342TS/N1,512 application, or UDA1342TS/N1,512 equivalent, this page delivers verified technical context, confirmed pin functions, real-world audio interface configurations (I2S/MSB/LSB-justified), and validated alternative CODECs for portable digital audio designs.
Technical Context
The UDA1342TS/N1,512 operates exclusively in slave mode, requiring an external system clock (256fs–768fs) synchronized to BCK/WS timing; it implements bitstream conversion with 5th-order noise shaping at 64fs and FSDAC reconstruction, eliminating need for analog post-filtering. Its dual stereo ADC front-end includes programmable gain amplifiers (0–24 dB, 3 dB steps) and DC cancellation filters per channel.
Digital audio processing includes independent left/right logarithmic volume control, bass boost, treble, de-emphasis (32/44.1/48/96 kHz), soft mute (24 ms cosine roll-off), and quick mute (750 μs), all configurable via L3-bus, I2C-bus, or static pin modes; the DAC supports 1fs output while ADC accepts 1fs–4fs input formats with oversampling rate selection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.7–3.6 V analog/digital rails; enables battery-powered portable operation without level-shifting. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar audio CODEC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AK4552VN | 24-bit, 96 kHz max sampling; I2C-only control; no static pin mode; 3.3 V only supply. | Requires external I2C master; lacks double-differential ADC mode and L3-bus compatibility. | Preferred when I2C ecosystem is standardized and higher SNR (105 dB) is prioritized over pin-mode flexibility. |
| CS4344-KSZ | Stereo DAC-only (no ADC); 24-bit, 96 kHz; SPI/I2C control; 3.3 V supply; no tone controls or de-emphasis. | Cannot replace full CODEC functionality; suitable only for playback-only systems with separate ADC. | Select when design separates ADC/DAC paths and requires ultra-low THD+N (−105 dB) for premium audio output stage. |
Compared with UDA1342TS/N1,512, AK4552VN offers higher SNR but removes static pin configuration and double-differential capability, while CS4344-KSZ reduces integration by omitting ADC and DSP features - making UDA1342TS/N1,512 uniquely suited for compact, self-contained portable recorders needing both conversion directions and embedded audio processing.

FAQ
What is the maximum sampling frequency supported by the UDA1342TS/N1,512 in full-feature mode?
The UDA1342TS/N1,512 supports up to 110 kHz sampling frequency for the CODEC as a whole. However, full-feature operation (including de-emphasis, tone control, and digital mixing) is guaranteed only up to 96 kHz in L3-bus or I2C-bus mode. At 110 kHz, only basic ADC/DAC conversion remains functional - all DSP features are disabled per datasheet Table 4.
Does the UDA1342TS/N1,512 require external analog filters for DAC output?
No, the UDA1342TS/N1,512 does not require external analog post-filtering for DAC output. Its Filter Stream DAC (FSDAC) architecture incorporates inherent reconstruction filtering, delivering a clean 0.9 VRMS line-level output with >100 dB SNR and −90 dB THD+N at 48 kHz without additional RC or op-amp stages.
Can the UDA1342TS/N1,512 operate with a 5 V digital interface while powered from 3.3 V supplies?
Yes, the UDA1342TS/N1,512 features 5 V tolerant digital inputs (SYSCLK, BCK, WS, L3DATA, L3CLOCK, L3MODE, STATIC, IPSEL, QMUTE, TEST1) and outputs (DATAO, STATUS), allowing direct interfacing with 5 V logic systems while operating from 2.7–3.6 V analog/digital supplies - simplifying level translation in mixed-voltage designs.
How does double differential mode improve audio performance in the UDA1342TS/N1,512?
In double differential mode, the UDA1342TS/N1,512 uses both stereo ADC pairs (VINL1/VINR1 and VINL2/VINR2) to process a single stereo signal, achieving −93 dB THD+N and 101 dB SNR at 48 kHz - a 1–3 dB improvement over normal mode. This mode enhances common-mode noise rejection and effective resolution for high-fidelity portable recording.
What are the power-down current specifications for the UDA1342TS/N1,512 ADC and DAC sections?
The UDA1342TS/N1,512 ADC section draws 200 μA in power-down state, while the DAC section consumes 250 μA when powered down. These ultra-low quiescent currents enable extended battery life in portable devices - for example, a typical MiniDisc recorder can achieve >15 hours of standby time using these power-down states.
