Description

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

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.
