UDA1342TS/N1,518 stereo audio CODEC IC
The UDA1342TS/N1,518 is a highly integrated 24-bit stereo audio CODEC IC designed for portable and consumer audio applications requiring both recording and playback functionality. Housed in a compact 28-pin SSOP package, this single-chip solution integrates a 4-channel ADC (2 stereo inputs) and a 2-channel DAC (1 stereo output) using bitstream conversion techniques. It operates from a low 2.7V to 3.6V supply, making it ideal for battery-powered devices. The chip supports multiple serial data formats (I²S, LSB/MSB-justified) with sample rates from 16 kHz to 110 kHz and offers flexible control via I²C, L3 bus, or static pins, providing a complete analog front-end solution for digital audio systems.
Key Features & Benefits
The UDA1342TS stands out with its high integration and audio processing capabilities. It features Programmable Gain Amplifiers (PGA) on the ADC inputs and an integrated high-pass filter for DC offset cancellation, simplifying microphone input design. On the playback side, it includes built-in digital sound processing such as bass boost, treble control, de-emphasis (32/44.1/48/96 kHz), and digital volume/mute control, reducing the need for external components. The DAC output does not require external analog post-filtering, thanks to its integrated digital filter. With 5V-tolerant digital inputs and separate power control for ADC and DAC sections, it enables efficient power management in portable designs, extending battery life.
Alternative audio CODEC ICs
● UDA1341TS (NXP): An earlier-generation stereo audio CODEC with similar functionality but potentially lower resolution and fewer integrated DSP features, suitable for direct drop-in replacements in legacy designs.
● PCM3060 (Texas Instruments): A high-performance 24-bit stereo audio codec featuring a 106dB SNR and separate ADC/DAC power supplies, ideal for professional and high-fidelity audio equipment.
● WM8960 (Wolfson/Cirrus Logic): A popular low-power stereo codec with integrated headphone driver and Class D speaker amp, optimized for portable multimedia devices like smartphones and tablets.
● TDA7419 (STMicroelectronics): An audio processor with integrated 4-channel ADC and advanced DSP for car audio applications, offering more extensive equalization and filtering options.
