LM7121 - Texas Instruments

LM7121 235-MHz Tiny Low Power Voltage Feedback Amplifier

The LM7121 is a high performance operational amplifier which addresses the increasing AC performance needs of video and imaging applications, and the size and power constraints of portable applications. The LM7121 can operate over a wide dynamic range of supply voltages, from 5 V (single supply) up to ±15V (see Application and Implementation for more details.
