STLD1 Datasheet Power-line communication dual line driver Features Dual line driver suitable for differential or single-ended configuration Up to 18 V p-p single-ended, 36 V p-p differential output range Very high linearity for EMC compliance Externally configurable power amplifier topology QFN24 (4x4 mm) Up to 1.5 A max. current RMS Embedded overtemperature protection Suitable for any narrow-band power-line communication (PLC) applications Available in QFN24 (4x4x1 mm) package -40 C to +105 C temperature range Applications Smart metering, smart grid and Internet of Things applications Suitable for application designs compliant with CENELEC, FCC and ARIB regulations 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 Product status link 1.5 A and an output voltage swing-up to 18 V peak-to-peak single-ended / 36 V RMS STLD1 peak-to-peak differential. Order code Package Packing The STLD1 features a very low output impedance (down to 0.1 in the typical STLD1 Tray configuration) to ensure efficient transfer of power to very low impedance loads, QFN24 (4x4 typically between 5 and 100 . Tape and x1 mm) STLD1TR reel 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.
