General Description

The MAX4265–MAX4270 single-supply, 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 or better at frequencies below 5MHz and

-60dBc at a 100MHz frequency. 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 signal­processing applications that require low distortion and
wide bandwidth.

The MAX4265 single and MAX4268 dual unity-gain-stable
amplifiers have up to a 300MHz gain-bandwidth product.
The MAX4266 single and MAX4269 dual amplifiers have
up to a 350MHz bandwidth at a minimum stable gain of
+2V/V. The MAX4267 single and MAX4270 dual amplifiers
have a 200MHz bandwidth at a minimum stable gain of
+5V/V.

For additional power savings, these amplifiers feature a
low-power disable mode that reduces supply current to

1.6mA and places the outputs in a high-impedance state.
The MAX4265/MAX4266/MAX4267 are available in a
space-saving 8-pin µMAX package, and the MAX4268/
MAX4269/MAX4270 are available in a 16-pin QSOP pack­age.
