The MAX4102/MAX4103 op amps combine high-speed performance and ultra-low differential gain and phase while drawing only 5mA of supply current. The MAX4102 is compensated for unity-gain stability, while the MAX4103 is compensated for a closed-loop gain (A_VCL) of 2V/V or greater.

The MAX4102/MAX4103 deliver a 250MHz -3dB bandwidth (MAX4102) or a 180MHz -3dB bandwidth (MAX4103). Differential gain and phase are an ultra-low 0.002%/0.002° (MAX4102) and 0.008%/0.003° (MAX4103), making these amplifiers ideal for composite video applications.

These high-speed op amps have a wide output voltage swing of ±3.4V (R_L = 100Ω) and 80mA current-drive capability.
