6.1 Overview

The THS6232 is a differential line-driver amplifier with a current-feedback architecture. The device is targeted for use in line-driver applications such as narrow-band and broadband power-line communications (PLC) that are often found in smart-metering and home-networking applications.

The THS6232 is designed as a single-port differential line driver. The integrated common-mode buffer featured in the THS6232 reduces the number of external components required for level shifting the input common-mode voltage in PLC applications that are often ac coupled, resulting in space savings on the circuit board and reducing the overall system cost. The two current-feedback amplifiers (D1 and D2) can be used independently. However, as a result of the THS6232 architecture, ensure that the internal CM buffer and resistors between the noninverting inputs are taken into consideration for the application use case.

The architecture of the THS6232 is designed to provide maximum flexibility with adjustable power bias modes that are selectable based on application performance requirements. The device also provides an external current adjustment pin (IADJ) to further optimize the quiescent power of the device. The wide output swing (19VPP) into 50Ω differential loads with 12V power supplies and high current drive of the THS6232 make the device an excellent choice for high-power, line-driving applications. By using 40V power supplies with a good thermal design that keeps the device within the safe operating temperature range, the THS6232 is capable of swinging 70VPP into 100Ω loads.
