400MHz, Ultra-Low-Distortion Op Amps

The MAX4108/MAX4109/MAX4308/MAX4309 op amps combine ultra-high-speed performance with ultra-low-distortion operation. The MAX4108 is compensated for unity-gain stability; the MAX4109, MAX4308, and MAX4309 are compensated for minimum closed-loop gains (AVCL) of 2V/V, 5V/V, and 10V/V, respectively.

The MAX4108 delivers a 400MHz unity-gain bandwidth with a 1200V/µs slew rate. An ultra-low-distortion design provides an unprecedented spurious-free dynamic range of -93dBc (MAX4108) at 5MHz (VOUT = 2VP-P, RL = 100Ω), making these amplifiers ideal for high-performance RF signal processing.

These high-speed op amps feature a wide output voltage swing and a high-current output-drive capability of 90mA.
