11 / 19 page  ±5V Typical Performance Characteristics (A V = +2, RL = 100Ω,VCC = ±5V; Unless Specified) (Continued) Application Division CLC5632 Operation The CLC5632 is a current feedback buffer fabricated in an advanced complementary bipolar process. The CLC5632 operates from a single 5V supply or dual ±5V supplies. Operating from a single 5V supply, the CLC5632 has the following features: • Gains of ±1, −1, and 2V/V are achievable without exter- nal resistors • Provides 100mA of output current while consuming only 15mW of power • Offers low −79/−81dBc 2nd & 3rd harmonic distortion • Provides BW80MHz and 1MHz distortion <−75dBc at V O =2V PP The CLC5632 performance is further enhanced in ±5V sup- ply applications as indicated in the ±5V Electrical Charac- teristics table and the ±5V Typical Performance plots. If gains other than +1, −1, or +2V/V are required, then the CLC5602 can be used. The CLC5602 is a current feedback amplifier with near identical performance and allows for ex- ternal feedback and gain setting resistors. Current Feedback Amplifiers Some of the key features of current feedback technology are: • Independence of AC bandwidth and voltage gain • Inherently stable at unit gain • Adjustable frequency response with feedback resistor • High slew rate • Fast Settling Current feedback operation can be described using a simple equation. The voltage gain for non-inverting or inverting current feedback amplifier is approximated by Equation 1.
