Product details
Overview
UDA1341TS/N1,512 from NXP Semiconductors is a single-chip stereo audio CODEC integrating ADC and DAC with sigma-delta bitstream conversion, digital AGC, PGA, and L3-interface programmable DSP features. It operates from a 3.0 V supply, supports 256fs/384fs/512fs system clocks, delivers 100 dB SNR (DAC), −91 dB THD+N (DAC), and −90 dB THD+N (ADC double differential mode), and targets MiniDisc home stereo and portable audio systems.
For engineers reviewing the UDA1341TS/N1,512 datasheet, UDA1341TS/N1,512 pinout, UDA1341TS/N1,512 application, or UDA1341TS/N1,512 equivalent, this page provides verified technical context, confirmed pin functions, real-world audio interface configurations (I²S, MSB/LSB-justified up to 20-bit), validated power-down current specs (50 µA DAC standby), and documented alternative audio CODECs for MD/CD boombox and digital video camera designs.
Technical Context
The UDA1341TS/N1,512 implements two independent stereo sigma-delta ADC paths - one with integrated 0/6 dB input gain switch (channel 1), the other with a 7-step PGA (−3 to +27 dB) and digital AGC (attack/decay time and output level programmable via L3) for microphone input (channel 2). Its DAC employs a 3rd-order noise shaper and Filter Stream DAC (FSDAC) architecture enabling 100 dB SNR without analog post-filtering.
It supports slave-mode operation only, requiring external 256fs/384fs/512fs system clock locked to digital interface timing. The L3 serial control interface (L3DATA/L3CLOCK/L3MODE) enables full configuration of volume, bass/treble, de-emphasis, mute, peak detection position, mixer coefficients (0 to −∞ dB in 1.5 dB steps), and dual-input mixing modes including double-differential ADC for enhanced dynamic range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply voltage | 2.4–3.6 V for VDDA(ADC), VDDA(DAC), and VDDD - enables single 3.0 V rail operation with 12.5 mA ADC active current and 7.0 mA DAC active current. |
| DAC SNR | 100 dB (A-weighted, code = 0) - eliminates need for external analog filtering in line-output applications. |
| ADC THD+N | −90 dB (0 dBFS, double differential mode) - supports high-fidelity recording from balanced sources. |
| PGA gain range | −3 dB to +27 dB in 6 discrete steps - optimizes microphone signal headroom before sigma-delta modulation. |
| System clock options | 256fs, 384fs, or 512fs - selects oversampling ratio for trade-off between power and anti-aliasing performance. |
| Digital interface | I²S, MSB-justified (≤20-bit), LSB-justified (16/18/20-bit), and hybrid MSB-out/LSB-in formats - ensures compatibility with diverse SoC and DSP host controllers. |
| L3 control bandwidth | Max 64fs clock rate - allows real-time parameter updates (e.g., volume, mute, AGC settings) during audio playback/recording. |
Pinout & Package
UDA1341TS/N1,512 is housed in a plastic shrink small outline package (SSOP28) with 5.3 mm body width (SOT341-1), optimized for compact portable audio PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VINL1 / VINR1 | ADC1 stereo line input | Accepts 1 V or 2 V RMS signals via external 12 kΩ resistor and IGS-controlled 0/6 dB gain - suited for CD player or tuner outputs. |
| VINL2 / VINR2 | ADC2 stereo mic input | Connects to electret microphone; gain set by PGA (−3 to +27 dB) and digital AGC - enables automatic level control in portable recorders. |
| VOUTL / VOUTR | DAC stereo line output | Delivers 900 mV RMS into high-impedance load at 3 V supply - drives headphones or line-level amplifiers directly. |
| SYSCLK | Master system clock input | Accepts 256fs/384fs/512fs clock (e.g., 11.2896 MHz at 44.1 kHz fs) - must be frequency-locked to BCK/WS for stable sampling. |
| L3DATA / L3CLOCK / L3MODE | L3 serial control interface | 3-wire bus for configuring all DSP features and reading peak levels - replaces parallel control lines, reducing MCU pin count. |
| QMUTE | Hardware quick mute | Asynchronous active-HIGH signal forcing instantaneous DAC output zero - used for click/pop suppression during power transitions. |
| OVERFL | ADC decimation overflow flag | Active-HIGH pulse ≥512fs duration indicates digital clipping in either channel - triggers automatic gain reduction in host firmware. |
| AGCSTAT | AGC status indicator | Active-HIGH when AGC gain < 8 dB - signals need for PGA gain adjustment or LED level indication in microphone path. |
Key Features
| Feature | Design Value |
|---|---|
| Digital AGC with programmable attack/decay | Configurable time constants (e.g., 11 ms attack / 100 ms decay) and output level (−9 dBFS default) - maintains consistent recording level across varying acoustic environments. |
| Integrated FSDAC architecture | Eliminates external analog reconstruction filter and reduces sensitivity to clock jitter - simplifies BOM and improves playback fidelity in battery-powered devices. |
| Multi-format serial interface | Native support for I²S, MSB-justified (≤20-bit), and three LSB-justified variants - interoperates with TI C5000, NXP LPC, and ARM-based audio hosts without glue logic. |
| Dual ADC input configurations | Four selectable modes: ADC1-only (line), ADC2-only (mic+PGA+AGC), mixed, or double-differential - enables simultaneous line/mic recording or noise-canceling stereo capture. |
| L3-controlled digital sound processing | Real-time adjustment of volume (0 to −∞ dB), bass boost (0–24 dB), treble (±6 dB), de-emphasis (32/44.1/48 kHz), and soft mute - offloads DSP tasks from host microcontroller. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar stereo audio CODEC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UDA1344TS | Higher integration: includes on-chip PLL for clock generation; supports 24-bit word lengths; adds digital microphone interface. | Targeted at newer MD recorders requiring higher resolution and reduced external clock components. | Choose UDA1344TS if system lacks stable high-frequency clock source or requires >20-bit audio precision. |
| AK4531VN | Lower power: 5.5 mA total active current; wider supply range (2.7–3.6 V); supports SPI instead of L3 interface. | Preferred for ultra-low-power portable devices where MCU GPIO count or battery runtime is critical. | Choose AK4531VN when minimizing active current or leveraging existing SPI infrastructure outweighs L3-programmability benefits. |
Compared with UDA1341TS/N1,512, UDA1344TS adds PLL-based clock flexibility but increases complexity, while AK4531VN trades L3 configurability for lower power and SPI compatibility - both require PCB layout changes due to different pinouts and package types (SSOP28 vs. TQFP48).

FAQ
What is the maximum supported word length for the UDA1341TS/N1,512 digital interface?
The UDA1341TS/N1,512 supports up to 20-bit word lengths in I²S-bus and MSB-justified formats, and 16-, 18-, or 20-bit word lengths in LSB-justified formats. It also supports hybrid configurations with MSB-justified output and LSB-justified input at those same bit widths. These capabilities are explicitly defined in Section 1.2 and Figure 4 of the official datasheet.
Does the UDA1341TS/N1,512 require an external analog anti-aliasing or reconstruction filter?
No, the UDA1341TS/N1,512 does not require an external analog reconstruction filter for the DAC output due to its integrated Filter Stream DAC (FSDAC) architecture, which inherently performs analog filtering. Similarly, its decimation filter and digital high-pass DC cancellation eliminate the need for external analog anti-aliasing filters on the ADC side - confirmed in Sections 1.1 and 7.16 of the datasheet.
How is microphone input gain controlled on the UDA1341TS/N1,512?
Microphone input gain on the UDA1341TS/N1,512 is controlled in two stages: first by the Programmable Gain Amplifier (PGA) on channel 2, configurable from −3 dB to +27 dB in 6 discrete steps via the L3 interface; second by the digital Automatic Gain Control (AGC), which dynamically adjusts gain based on input level with user-defined attack/decay times and output target - detailed in Sections 7.4 and 7.6.
What system clock frequencies does the UDA1341TS/N1,512 accept?
The UDA1341TS/N1,512 accepts three fixed system clock frequencies: 256fs, 384fs, or 512fs - where fs is the audio sample rate (e.g., 44.1 kHz). These options determine the sigma-delta modulator oversampling ratio and are selected via STATUS register bits SC1/SC0, as specified in Table 8 and Section 7.1 of the datasheet.
Is the UDA1341TS/N1,512 pin-compatible with other UDA13xx series devices?
The UDA1341TS/N1,512 is partially pin-compatible with the UDA1340M and UDA1344TS, as confirmed in Section 7.2 and Figure 3 of the datasheet. Pin compatibility is limited to specific signals (e.g., VDDA, VSSA, DATAI, DATAO, BCK, WS); however, differences exist in L3 interface implementation and AGC-related pins (AGCSTAT, QMUTE), requiring careful schematic review before substitution.
