MAX4265MAX4270 19-1552 Rev 2 8/00 Ultra-Low-Distortion, +5V, 400MHz Op Amps with Disable General Description Features The MAX4265MAX4270 ultra-low distortion, voltage-feed- Operates from +4.5V to +8.0V back op amps are capable of driving a 100 load while Superior SFDR with 100 Load maintaining ultra-low distortion over a wide bandwidth. -90dBc (f = 5MHz) C They offer superior spurious-free dynamic range (SFDR) -59dBc (f = 100MHz) performance: -90dBc at 5MHz and -59dBc at 100MHz C (MAX4269). Additionally, input voltage noise density is 35dBm IP3 (f = 20MHz) C 8nV/Hz while operating from a single +4.5V to +8.0V sup- 8nV/Hz Voltage Noise Density ply or from dual 2.25V to 4.0V supplies. These features make the MAX4265MAX4270 ideal for use in high-perfor- 100MHz 0.1dB Gain Flatness (MAX4268) mance communications and signal-processing applica- 900V/s Slew Rate tions that require low distortion and wide bandwidth. 45mA Output Driving Capability The MAX4265 single and MAX4268 dual amplifiers are Disable Mode Places Outputs in High-Impedance unity-gain stable. The MAX4266 single and MAX4269 dual amplifiers are compensated for a minimum stable gain of State +2V/V, while the MAX4267 single and MAX4270 dual amplifiers are compensated for a minimum stable gain of +5V/V. For additional power savings, these amplifiers feature a low-power disable mode that reduces supply current Ordering Information and places the outputs in a high-impedance state. The MAX4265/MAX4266/MAX4267 are available in a space- PART TEMP.
