Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The PCM5140QRGERQ1 device is an automotive-grade four-channel, 768kHz Burr-Brown™ audio analog-to-digital converter (ADC) with a 120dB SNR launched by (TI). The following are its key parameters

Type: Audio

Number of channels: 4

Resolution (bits) : 16 b, 20 b, 24 b, 32 b

Sampling rate (per second) : 768k

Data interfaces: I2C, I2S, TDM

Power supply voltage source: Single power supply

Voltage - Power supply: 1.7V - 1.9V, 3V - 3.6V, 1.65V - 1.95V, 3V - 3.6V

Operating temperature: -40°C to 125°C

Installation type: Surface mount type

Grade: Automotive grade

Qualification: AEC-Q100

Package/Housing: 24-VQFN (4x4)

In addition, the PCM5140QRGERQ1 integrates programmable channel gain, digital volume control, programmable microphone bias voltage, phase-locked loop (PLL), programmable high-pass filter (HPF), dual second-order filters, low-latency filter mode, and can achieve a sampling rate of up to 768kHz. And it can achieve a sampling rate as high as 192kHz. The PCM5140QRGERQ1 supports Time Division Multiplexing (TDM), I2S or Left Balanced (LJ) audio formats and can be controlled via I2C or SPI. These integrated high-performance features, along with the function of being powered by a single 3.3V or 1.8V supply, make the PCM5140QRGERQ1 device highly suitable for space-constrained audio systems in far-field microphone recording applications.

Application scenarios

The PCM5140QRGERQ1 is suitable for scenarios with high requirements for performance and stability, such as automotive audio systems and industrial-grade audio acquisition devices.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
