Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

From the millisecond-level noise reduction of true wireless earphones to the immersive surround sound of car audio systems, high-fidelity audio processing technology is becoming the "sensory soul" of consumer electronics and automotive intelligence. Texas Instruments (TI) continues to define the performance boundaries of audio processing chips with its Burr-Brown™ technology heritage, automotive-grade reliability and ultra-low power architecture. Shenzhen Mingjiada Electronics Co., LTD., relying on its direct supply channels from the original factory and a million-level inventory reserve, provides global customers with one-stop audio solutions from "signal collection to power output", allowing every sound wave to carry the ultimate emotional experience.

I. Technological High Ground: The Three Disruptive Genes of TI Audio Chips

1. High-fidelity sound quality: Burr-Brown™ 's "Right for Students with Excellent Vocal Performance

TI audio chips inherit the core technology of Burr-Brown™ and achieve industry-leading acoustic performance through an ultra-low distortion architecture and high dynamic range design

24-bit audio ADC (such as PCM6140QRGERQ1) : The signal-to-noise ratio (SNR) reaches 103dB, supporting a sampling rate of 768kHz, precisely capturing the minute sound field details that are difficult for the human ear to perceive.

32-bit Dacs (such as PCM5101) : With total harmonic distortion (THD) as low as -105dB, they reproduce the original sound density of a recording studio and become the "heart" of high-end Hi-Fi equipment.

2. Automotive-grade reliability: The "Survival Rule" in Extreme environments

AEC-Q100 certification: Resistant to a wide temperature range of -40 ° C to 125 ° C and 50G mechanical shock (such as PCM6140QRGERQ1), ensuring zero distortion of audio signals in engine compartment vibration environments.

Anti-interference enhancement: Integrated ±10kV ESD protection and power isolation technology to eliminate the interference of vehicle-mounted electromagnetic noise on the microphone array.

3. Intelligent Integration: The "Subtraction Art" of System Design

Single-chip multi-channel integration: For instance, TLV320AIC3254 integrates ADC/DAC/ codec/headphone amplifier, replacing traditional discrete solutions and reducing PCB area by 60%.

Programmable DSP core: Supports active noise cancellation (ANC) algorithms and 3D audio effect tuning, reducing the development cycle by 50%.

Ii. Mingjiada Supply Matrix: The "Golden Triangle" Covering the Entire Acoustic Chain

1. Audio codec: The "Vocal Cords and Hearing" of Smart Devices

Multi-scenario voice interaction: The TLV320AIC3104 supports dual-microphone beamforming, achieving 5-meter far-field sound pickup, making it the core of conference speakers and voice assistants.

Lossless Bluetooth transmission: The AIC3256 integrates aptX™ HD codec, with a wireless transmission bit rate of up to 576kbps, surpassing the CD audio quality standard.

2. High-precision ADC: The "Digital Catcher" of Sound Signals

Vehicle-mounted microphone array: PCM6140QRGERQ1 supports four-channel PDM microphone synchronous sampling and is compatible with the intelligent cabin noise cancellation system.

Medical auscultation equipment: ADS131M08 offers 24-bit microvolt-level acquisition accuracy, and the accuracy of pathological murmur recognition has been increased by 40%.

3. High-performance DAC: The "Analog Translator" of the Digital World

Professional audio system: The PCM1794A has a dynamic range of up to 132dB, meeting the mastering level playback requirements of recording studios.

Battery-free TWS headphones: The DAC3110 has A standby power consumption as low as 0.1μA and is equipped with energy harvesting technology to achieve permanent battery life.

Iii. Four Major Supply Advantages of Mingjiada: Solving Industry pain Points

1. The iron law of traceability for genuine products from the original factory

Ensure that all components are purchased from original factory channels or authorized channels to eliminate the risks of refurbishment and counterfeiting.

2. Global dual-warehouse lightning-fast delivery

Shenzhen Central Warehouse + Hong Kong constant Temperature Warehouse: The regular inventory of main models (such as PCM5101, TLV320AIC3254) is over 5,000 pieces, and emergency orders can be responded to within 24 hours.

Cross-border DDP door-to-door: Orders from Europe, America and Southeast Asia will be delivered within 72 hours. Anti-static cold chain logistics ensures zero damage to the chips.

3. Flexible procurement strategies

R&d support: Some products support a minimum order of 1 piece and are supplied in split plates. For specific details, please contact the customer service staff of Mingjiada for consultation.

Mass production support: The price for orders of tens of thousands of pieces is 12% lower than the market price, and VMI consignment is supported to reduce inventory pressure.

With the original factory's resource penetration power, the resilience of a supply chain worth tens of millions, and the empowerment of acoustic technology, Mingjiada Electronics transforms the "performance parameters" of Burr-Brown™ into the "sensory barriers" of customers' products - allowing every decibel to carry emotions and every Hertz to penetrate the soul.
