6.1 Overview

The THS6212 is a differential line-driver amplifier with a current-feedback architecture. The device is targeted for use in line-driver applications (such as wide-band power-line communications) and is fast enough to support transmissions of 14.5-dBm line power up to 30 MHz.

The THS6212 is designed as a single-channel device that can be a drop-in replacement for dual-channel footprint packages. The package pinout is compatible with the pinout of the THS6214 dual, differential line driver, and provides an alternative for systems that only require a single-channel device.

The architecture of the THS6212 is designed to provide maximum flexibility with multiple bias settings that are selectable based on application performance requirements, and also provides an external current pin (IADJ) to further adjust the bias current to the device. The wide output swing (49VPP) and high current drive (650mA) of the THS6212 make the device an excellent choice for high-power, line-driving applications.

The THS6212 features thermal protection that typically triggers at a junction temperature of 175°C. The device behavior is similar to the bias off mode when thermal shutdown is activated. The device resumes normal operation when the die junction temperature reaches approximately 145°C. The device can go in and out of thermal shutdown until the overload conditions are removed because of the unpredictable behavior of the overload and thermal characteristics.
