AMC1200BDUBR - Precision Current Sense Basic Isolation Amplifier, SOP-8

Model: AMC1200BDUBR

Package: SOP-8

Type: Isolated Amplifier

Overview：AMC1200BDUBR is a high precision isolation amplifier that isolates the output and input circuits with a high magnetic field immunity silicon dioxide (SiO2) barrier. The device delivers excellent performance and supports precise current control to reduce system-level power consumption, especially in motor control applications, and torque ripple. The common mode voltage of the output signal is automatically regulated to the 3V or 5V low side supply voltage.

AMC1200BDUBR - Product Features:

±250mV input voltage range optimised for shunt resistors

Very low non-linearity: 0.075% maximum at 5V

Low offset error: 1.5mV maximum

Low noise: 3.1mVRMS (typical)

Low high-side supply current:

8mA at 5V maximum

Input bandwidth: 60kHz minimum

Fixed Gain: 8 (0.5% accuracy)

High common mode rejection ratio: 108dB

3.3V low-side operating voltage

Isolation voltage: 4250 VPEAK 

Operating voltage: 1200 VPEAK

Transient immunity: 10kV/µs (min)

AMC1200BDUBR - Applications:

Current sensing based on shunt resistors in the following applications:

Motor Control

Green energy

Frequency inverters

Uninterruptible Power Supplies

• 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.
