Differential amplifier for 50 MHz signal paths
Its 50 MHz -3dB bandwidth covers standard-definition analog video (NTSC/PAL) and many baseband communication links, while the differential output type simplifies driving twisted-pair or balanced lines. The part operates from either a single supply (6V to 8V) or dual supplies (±3V to ±8V), giving flexibility in mixed-signal systems where ±5V analog rails are already present. Supply current is 18 mA, moderate for this bandwidth class, and each channel can deliver 4 mA output current into a load.
The ±3V to 8V supply range means the TL592B-8D can be dropped into a ±5V analog section without an extra regulator, or run from a single 5V rail if the system uses that. The 4 mA output per channel is enough to drive a 75 Ω video load (with external termination) or feed the input of a subsequent amplifier stage. For a 50 MHz part, the 18 mA supply current is reasonable — expect to budget about 90 mW from a ±5V supply.
