Features
- Precision Input Range and Fixed Gain:
- This circuit offers a ±250-mV input voltage range specifically optimized for current measurements using shunt resistors. This device's fixed gain of 8.2 V/V guarantees steady and dependable input signal amplification, which makes it perfect for accurate current sensing applications.
- Low DC Errors:
- Designed with minimal DC errors, it features an offset error of ±0.2 mV (max), offset drift of ±3 μV/°C (max), gain error of ±0.3% (max), gain drift of ±50 ppm/°C (max), and nonlinearity of 0.03% (max). The dependability of the measurements is increased by these criteria, which ensure excellent accuracy and stability under a variety of operating situations.
- Robust Isolation and Safety:
- This amplifier provides robust system-level diagnostic capabilities, including 5000-VRMS isolation for 1 minute as per UL1577 standards. High-level isolation like this guarantees dependability and safety, particularly in harsh industrial settings where electrical isolation is essential.
- Wide Operational Range:
- This circuit operates on a 3.3-V supply for both the high-side and low-side, making it versatile for various system configurations. Additionally, it is fully specified to function over an extended industrial temperature range from –40°C to +125°C, ensuring dependable performance in extreme conditions.
Application
- AC Motor Drives:
- It is typically used in AC motor drives to monitor the load current. An external shunt resistor (RSHUNT) senses the current, and the AMC1301DWVR detects the voltage drop across this resistor. It then digitizes the analog input signal on the high-side and transfers the data across the isolation barrier. On the low-side, the signal is reconstructed and presented as a differential voltage on the output pins.
- High-Noise Environments:
- It is designed for reliable and accurate operation in high-noise environments. Its differential input and output, combined with high common-mode transient immunity (CMTI), ensure stable performance even under significant electrical noise.
- Shunt-Resistor-Based Current Sensing:
-
Applications using shunt-resistor-based current sensing are best suited for this circuit. It is frequently utilized in:
– Motor drives
– Frequency inverters
–Uninterruptible Power Supplies (UPS)
And it is appropriate for these crucial applications due to its precision and isolation characteristics.
