Power-line communication dual line driver

The STLD1 line driver is a low-distortion, high-current dual power amplifier specifically designed for power-line communication applications, where high output current drives the AC power-line loads.

Operating on a single 8-18 V supply, the STLD1 can deliver high output current up to 1.5 ARMS and an output voltage swing-up to 18 V peak-to-peak single-ended / 36 V peak-to-peak differential.

The STLD1 features a very low output impedance (down to 0.1 Ω in the typical configuration) to ensure efficient transfer of power to very low impedance loads, typically between 5 Ω and 100 Ω.

The device has very low in-band and out-of-band two-tone intermodulation distortion (IM3) as well as very high spurious-free dynamic range (SFDR) to guarantee and meet CENELEC, ARIB and FCC emission requirements.

It also features thermal shutdown as well as current sense output.
