STMicroelectronics has introduced a pair of wideband op amps that provide the high-output current required to drive xDSL line interfaces and multiple video lines.

The TS615 and TS616 are dual current-feedback op amps that feature s slew rate of 410V/?s and a -3dB bandwidth of 40MHz, for an output current of 410mA. The high slew rate helps control harmonic distortion and intermodulation.

Both operate from 2.5V to 6V dual supply voltage, or from 5V to 12V on a single supply voltage. This capability allows the op amps the ability to drive a differential load of 50 ohms with a swing of 21V (from a 12V power supply) and a differential load of 25 ohms with a swing of 7.6V (from a 5V power supply).

Housed in a TSSOP14 EPAD package, the TS615 has a power down function with low output impedance to maintain line matching even when the part is in sleep mode. The TS616, on the other hand, is offered in an SO8 EPAD package.
