Miniature, 300MHz, Single-Supply, Rail-to-Rail Op Amps with Enable

The MAX4212/MAX4213 single, MAX4216 dual, MAX4218 triple, and MAX4220 quad op amps are unity-gain-stable devices that combine high-speed performance 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 systems that require wide bandwidth, such as video, communications, 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 package, 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.
