Linear Technology LT1993-4
The LT1993-4 has been designed for ease of use, with minimal support circuitry required. The output common mode voltage is easily set via the VOCM pin, eliminating either an output transformer or AC-coupling capacitors in many applications. The LT1993-4 is designed to meet the demanding requirements of communications transceiver applications.FEATURES
