LM7121
- (Typical Unless Otherwise Noted).
VS = ±15 V - Easy to use Voltage Feedback Topology
- Stable with Unlimited Capacitive Loads
- Tiny SOT23-5 Package — Typical
Circuit Layout Takes Half the
Space Of SO-8 Designs - Unity Gain Frequency: 175 MHz
- Bandwidth (−3 dB, AV = +1, RL
= 100Ω): 235 MHz - Slew Rate: 1300V/µs
- Supply Voltages:
- SO-8: 5 V to ±15 V
- SOT23-5: 5 V to ±5 V
- Characterized for: +5 V, ±5 V, ±15 V
- Low Supply Current: 5.3 mA
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). It offers an excellent speed-power product delivering 1300 V/µs and 235 MHz Bandwidth (−3 dB, AV = +1). Another key feature of this operational amplifier is stability while driving unlimited capacitive loads.
Due to its tiny SOT23-5 package, the LM7121 is ideal for designs where space and weight are the critical parameters. The benefits of the tiny package are evident in small portable electronic devices, such as cameras, and PC video cards. Tiny amplifiers are so small that they can be placed anywhere on a board close to the signal source or near the input to an A/D converter.
