Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The INA2134UA is a dual-channel differential line receiver designed specifically for high-performance audio systems. It features integrated precision laser-trimmed resistors and high-speed operational amplifiers with a fixed gain of 0 dB (1 V/V), enabling easy balanced-to-unbalanced conversion and significantly suppressing common-mode noise. The device is packaged in a 14-SOIC package and is suitable for professional audio, broadcasting equipment, and high-end consumer audio products.

INA2134UA Features

• Dual-channel independent differential amplifiers with extremely low channel crosstalk

• Fixed gain of 0 dB (1 V/V), eliminating the need for external gain resistors

• Ultra-low distortion: 0.0005% (typical at 1 kHz)

• High slew rate: 14 V/µs, ensuring fast dynamic response

• High common-mode rejection ratio: 90 dB (typical), effectively eliminating noise interference

• Wide supply voltage range: ±4 V to ±18 V (single supply 8 V to 36 V)

• Low quiescent current: 2.4 mA per channel (typical)

• Full temperature industrial grade: -40 °C to +85 °C

• 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.
