Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The LMH32404QWRHFRQ1 is a four-channel, single-ended input-to-differential output transimpetry amplifier (TIA), suitable for light detection and ranging (LIDAR) applications and laser ranging systems. Its main features include:

• Comply with the EC-Q100 standard for automotive applications:

-Temperature grade 1: -40 °C to +125°C, TA

• Gain: 20kΩ

• Performance, CPD = 1pF:

-Bandwidth: 350 MHz

- Input reference noise: 56nARMS

- Rise and fall time: 1.25ns

• Static current: 28 mA per channel

• Standby mode: 10 mA/ channel

• Low power mode: 2.5mA (4 channels)

• Channel switching time: 10ns

• Integrated ambient light cancellation

• Integrated 100mA protection clamp

• 4 input channels and 4 differential output channels

• Integrated multiplexers enable flexible configuration between optical sensors and ADC/TDC

• Multiple LMH32404s can be combined in parallel to achieve a wider FoV

The LMH32404QWRHFRQ1 integrates a 100mA clamp on each channel, which can provide protection for the amplifier and allow the device to quickly recover from overload input conditions. In addition, the LMH32404QWRHFRQ1 also provides an integrated ambient light elimination (ALC) circuit on each channel, which can replace the AC coupling between the photodiode and the amplifier, thereby saving board layout space and system costs. When measuring direct current and low frequencies, ALC circuits should be prohibited.

• 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.
