Ultra-Low-Distortion, +5V,

400MHz Op Amps with Disable

General Description

The MAX4265–MAX4270 ultra-low distortion, voltage-feed­back op amps are capable of driving a 100Ω load while
maintaining ultra-low distortion over a wide bandwidth.
They offer superior spurious-free dynamic range (SFDR)
performance: -90dBc at 5MHz and -59dBc at 100MHz
(MAX4269). Additionally, input voltage noise density is
8nV/√Hz while operating from a single +4.5V to +8.0V sup­ply or from dual ±2.25V to ±4.0V supplies. These features
make the MAX4265–MAX4270 ideal for use in high-perfor­mance communications and signal-processing applica­tions that require low distortion and wide bandwidth.

The MAX4265 single and MAX4268 dual amplifiers are
unity-gain stable. The MAX4266 single and MAX4269 dual
amplifiers are compensated for a minimum stable gain of
+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
and places the outputs in a high-impedance state. The
MAX4265/MAX4266/MAX4267 are available in a space­saving 8-pin µMAX®package, and the MAX4268/
MAX4269/MAX4270 are available in a 16-pin QSOP
package.
