The MAX4212/MAX4213 single, MAX4216 dual,
MAX4218 triple, and MAX4220 quad op amps are
unity-gain-stable devices that combine high-speed per-
formance with Rail-to-Rail
MAX4218 have a disable feature that reduces power-
supply current to 400µA and places the outputs into a
high-impedance state. These devices operate from a
3.3V to 10V single supply or from ±1.65V to ±5V dual
supplies. The common-mode input voltage range
extends beyond the negative power-supply rail (ground
in single-supply applications).
These devices require only 5.5mA of quiescent supply
current while achieving a 300MHz -3dB bandwidth and
a 600V/µs slew rate. Input-voltage noise is only
10nV/ Hz and input-current noise is only 1.3pA/ Hz for
either the inverting or noninverting input. These parts
are an excellent solution in low-power/low-voltage sys-
tems that require wide bandwidth, such as video, com-
munications, and instrumentation. In addition, when
disabled, their high-output impedance makes them
ideal for multiplexing applications.
The MAX4212 comes in a miniature 5-pin SOT23 pack-
age, while the MAX4213/MAX4216 come in 8-pin µMAX
and SO packages. The MAX4218/MAX4220 are available
in space-saving 16-pin QSOP and 14-pin SO packages.
