Product details
Overview
UDA1341TS/N1,518 from NXP Semiconductors is a single-chip stereo audio CODEC integrating ADC and DAC with digital sound processing, operating from a 3.0 V supply, supporting 256fs/384fs/512fs system clocks, and delivering 100 dB SNR in double-differential ADC mode for MiniDisc home stereo and portable applications.
For engineers reviewing the UDA1341TS/N1,518 datasheet, UDA1341TS/N1,518 pinout, UDA1341TS/N1,518 application, or UDA1341TS/N1,518 equivalent, key selection considerations include its L3-interface programmability, dual-input analog front end with PGA and digital AGC on channel 2, I²S/MSB/LSB data format flexibility, and FSDAC architecture eliminating need for external analog post-filtering.
Technical Context
The UDA1341TS/N1,518 implements sigma-delta conversion with 128× oversampling in both ADC and DAC paths, using a 3rd-order noise shaper (DAC) and 3rd-order Ritchie-coder modulators (ADC). Its decimation filter provides 108 dB dynamic range and ±0.05 dB passband ripple; interpolation filter delivers ±0.03 dB ripple and >50 dB stopband attenuation.
Digital signal processing includes programmable volume (−∞ to 0 dB in 1 dB steps), bass boost (0–24 dB), treble (0–12 dB), de-emphasis (32/44.1/48 kHz), soft mute, and peak detection with configurable position-fully controlled via 3-wire L3-interface (L3DATA/L3CLOCK/L3MODE) with address/data transfer modes and extended register access.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.4–3.6 V for ADC/DAC/digital supplies - enables single 3.0 V rail operation with 12.5 mA ADC and 7.0 mA DAC active current. |
| ADC SNR | 100 dB (A-weighted, double-differential mode) - supports high-fidelity microphone input capture without external preamp. |
| DAC SNR | 100 dB (A-weighted) - delivers line-level output (900 mV RMS) directly drivable by integrated FSDAC op-amps. |
| THD+N (DAC) | −91 dB (0 dBFS) - ensures low distortion playback even at full scale. |
| PGA Gain Range | −3 to +27 dB in 0.5 dB steps - allows precise microphone sensitivity matching via L3-interface. |
| AGC Control | Configurable attack/decay time and output level - enables automatic record-level optimization for portable MD recording. |

Pinout & Package
UDA1341TS/N1,518 is housed in a plastic shrink small outline package (SSOP28) with 28 leads and 5.3 mm body width (SOT341-1), optimized for compact audio subsystem layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VINL1 / VINR1 | ADC1 stereo line input | Supports 1–2 VRMS signals with selectable 0/6 dB gain; requires 12 kΩ series resistor for 2 VRMS operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar audio CODEC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| UDA1344TS | Partially pin-compatible SSOP28 successor with enhanced digital mixer and improved AGC algorithm; same 3.0 V supply and L3-interface. | Targets newer MD designs requiring higher integration density and lower THD+N (−93 dB vs −91 dB). | Select UDA1344TS when upgrading legacy UDA1341TS designs for improved dynamic range and mixer flexibility. |
| AK4531VN | 24-bit stereo CODEC in TSSOP28; supports I²S/PCM only (no LSB/MSB hybrid); requires separate 1.8 V digital supply. | Suitable for non-MD consumer audio where 24-bit resolution and lower power (8.5 mA total) outweigh format flexibility. | Choose AK4531VN for new designs prioritizing resolution and ultra-low power over L3-interface simplicity and multi-format compatibility. |
Compared with UDA1341TS/N1,518, UDA1344TS offers incremental improvements in AGC and mixer capability within identical footprint and control architecture, while AK4531VN trades L3 programmability and format versatility for higher resolution and lower power - making UDA1341TS/N1,518 optimal for cost-sensitive, L3-based MD and portable audio systems requiring proven reliability.

FAQ
What is the maximum supported word length for the UDA1341TS/N1,518 digital audio interface?
The UDA1341TS/N1,518 supports up to 20-bit word length in I²S-bus and MSB-justified formats, and 16/18/20-bit word lengths in LSB-justified and hybrid MSB-output/LSB-input configurations. This flexibility allows seamless integration with host processors offering varying data-width capabilities while maintaining compatibility with legacy 16-bit audio pipelines.
Does the UDA1341TS/N1,518 require external analog filtering on its DAC output?
No, the UDA1341TS/N1,518 does not require external analog post-filtering due to its Filter Stream Digital-to-Analog Converter (FSDAC) architecture. The integrated FSDAC inherently performs reconstruction filtering, delivering a clean 900 mV RMS line-level output directly suitable for driving headphones or line inputs without additional passive components.
How is microphone input gain controlled on the UDA1341TS/N1,518?
Microphone input gain on the UDA1341TS/N1,518 is controlled via the Programmable Gain Amplifier (PGA) on ADC channel 2, which is programmed through the L3-interface. The PGA offers seven discrete gain settings: −3, 0, 3, 9, 15, 21, and 27 dB, enabling precise matching to diverse microphone sensitivities without external amplification circuitry.
What system clock frequencies does the UDA1341TS/N1,518 support?
The UDA1341TS/N1,518 supports three selectable system clock frequencies: 256fs, 384fs, and 512fs - where fs is the audio sample rate (e.g., 44.1 kHz). These options are configured via the STATUS register's SC1/SC0 bits and must be locked in frequency to the digital interface signals (BCK/WS) for stable sigma-delta operation.
Can the UDA1341TS/N1,518 perform simultaneous line and microphone input recording?
Yes, the UDA1341TS/N1,518 supports simultaneous line and microphone input recording through its digital mixer function. In ADC1+ADC2 mixer mode, outputs from both stereo ADC channels (including PGA and digital AGC on channel 2) are mixed with programmable coefficients (0 to −∞ dB in 1.5 dB steps), enabling blended audio capture without external summing circuitry.
