General Description

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

outputs. The MAX4213/

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.

Miniature, 300MHz, Single-Supply, Rail-to-Rail Op Amps with Enable • Use surface-mount instead of through-hole components for better high-frequency performance. • Use a PC board with at least two layers; it should be as free from voids as possible. • Keep signal lines as short and as straight as possible. Do not make 90° turns; round all corners. Rail-to-Rail Outputs, Ground-Sensing Input The input common-mode range extends from (VEE - 200mV) to (VCC - 2.25V) with excellent commonmode rejection.
