Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ADA4937-1YCPZ is a low-noise, ultra-low distortion, high-speed differential amplifier. It is ideal for driving high-performance ADCs with resolutions up to 16 bits and a DC to 100 MHz bandwidth. The adjustable output common-mode level allows the ADA4937-1YCPZ to match the ADC's input. The internal common-mode feedback loop also provides excellent output balance and suppresses even-order harmonic distortion products.

For the ADA4937-1YCPZ, a simple external feedback network composed of four resistors can be easily used to configure the differential gain, with the feedback network determining the amplifier's closed-loop gain.

The ADA4937-1YCPZ is manufactured using ADI's proprietary silicon-germanium (SiGe) complementary bipolar process, enabling extremely low distortion levels with input voltage noise as low as 2.2 nV/√Hz. Low DC offset and excellent dynamic performance make the ADA4937-1/ADA4937-2 particularly suitable for various data acquisition and signal processing applications.

The ADA4937-1YCPZ is available in a 3 mm × 3 mm, 16-pin lead-free LFCSP package (ADA4937-1YCPZ, single-channel). The pin layout is optimised to facilitate PCB layout and minimise distortion. The ADA4937-1YCPZ is rated for an operating temperature range of -40°C to +105°C, suitable for automotive applications, with a power supply voltage range of 3.3 V to 5 V.

• 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.
