Hi Richard, Richard and Dave, at the risk of seeming obsessed with op amps I've dug up another two Natsemi devices: the LM7171 designed for ADSL and high definition TV line driver apps with a slew rate of 4.1 KV per uSec, unity gain bandwidth of 220 MHz and 100 mA output current. The next device is the LMH6672 which for similar apps to the LM7171 but lower slew rate at 170 V uSec ,lower noise, lower bandwidth (130 MHz 3 db down) and able to output 19 volts pk-pk into a 50 ohm load. Are these doovahs getting close to the ballpark performance required or should I start boning up on emitter followers?.
