THS6222IRGTR

Overview

The THS6222IRGTR is a differential line-driver amplifier manufactured using Texas Instruments' silicon-germanium process. It operates on an 8V to 32V supply range and features a current-feedback architecture. The device includes an integrated midsupply common-mode buffer, adjustable power modes, and overtemperature protection. It provides a large-signal bandwidth of 195MHz at 16VPP output swing and a slew rate of 5500V/µs. The component supports up to 338mA output current and offers low harmonic distortion characteristics suitable for demanding communication applications.

Feature Summary

• Integrated midsupply common-mode buffer eliminates external components
• Adjustable bias modes including full-bias, mid-bias, low-bias, and shutdown states
• High linearity with low harmonic distortion for heavy line loads
• Built-in overtemperature protection for system reliability

Applications

• SGCC HPLC line drivers and IEEE 1901.1 standards
• Power line communications gateways and smart meters
• Home networking PLC and data concentrators
• Differential DSL line drivers

Procurement Notes

Verify the specific package configuration matches the design requirements, as the THS6222 series includes both 16-pin and 24-pin VQFN options. Confirm that the ordering suffix corresponds to the intended reel or tape packaging format. Ensure compatibility with the required operating temperature range and verify that the IADJ pin connections align with the desired quiescent current settings for the application.

Selection Notes

Select this component when high linearity and wide dynamic range are required for driving heavy loads in broadband power line communications. The adjustable bias control allows optimization between performance and power consumption. Consider the thermal management requirements associated with the exposed thermal pad in the VQFN package to ensure reliable operation under maximum load conditions.

Part Context

This part belongs to the THS6222 family of differential line drivers designed for high-speed power line communications. It serves as a high-performance upgrade to previous generations like the THS6212. The device is specifically engineered to meet the stringent linearity and drive requirements of modern PLC standards such as G.hn, PRIME, and ISO 15118.

Replacement Considerations

The THS6222 is documented as a high-performance upgrade to the THS6212. Verify pinout compatibility and electrical specifications before substituting other devices in existing designs.
