The circuit uses OPA2662 internal dual OTA to constitute two-channel current output driver circuit, and input signals VIN1 and VIN2 are amplified by OPA2662 to output current IOUT1 and IOUT2 ​​for driving current to drive 75Ω cable and load. EN1, EN2 can control turning on or off of channels, when EN is in high level, the channel is turned on; when EN is in low level, the channel is turned off.
