Overview
The TPA8001-SOAR is a precision isolated amplifier from the 3PEAK TPA800X series, utilizing capacitive silicon dioxide insulation to separate input and output circuits. It features a fixed gain of 8.2 and an input voltage range of ±250 mV. The device achieves a common-mode transient immunity (CMTI) of 100 kV/µs and maintains a maximum gain error of 0.3% at 25°C. It operates within a temperature range of -40°C to +125°C and includes system-level diagnostic capabilities.
Feature Summary
- Capacitive SiO2 insulation barrier provides high reliability and enhanced common-mode transient immunity
- Integrated system-level diagnostics including fail-safe outputs for supply loss or overvoltage detection
- Optimized input design compatible with shunt resistors and low-voltage signal sources
Applications
- Industrial automation
- Motor control current sensing
- Power supplies
Procurement Notes
Verify the specific package type WSOP8 matches the required footprint. Confirm that the fixed gain of 8.2 aligns with the system's signal conditioning requirements. Ensure the operating environment stays within the specified -40°C to +125°C range. Check for any ongoing safety certifications if specific regulatory compliance is mandated for the final product integration.
Selection Notes
Select this component when a fixed gain of 8.2 is required for isolating signals from shunt resistors. It is suitable for applications demanding high CMTI in noisy environments like motor drives. Consider alternative models in the TPA800X series if different gain values or input ranges are needed. Verify that the differential output interface integrates correctly with downstream ADCs or gate drivers.
Part Context
The TPA8001-SOAR belongs to the TPA800X family of precision isolated amplifiers manufactured by 3PEAK. This series employs innovative circuit designs to optimize structure and significantly improve common-mode transient immunity. The devices are designed to connect directly to low-voltage level signal sources, supporting precise current control in industrial and automotive applications.
Replacement Considerations
TPA8000-SOAR offers a similar isolation architecture but with a fixed gain of 8.0 instead of 8.2. TPA8002-SOAR provides a higher fixed gain of 41 with a narrower ±50 mV input range. These alternatives share the same WSOP8 package and operational characteristics.
