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 powersupply current to 400A 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/s 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 MAX and SO packages. The MAX4218/MAX4220 are available in a space-saving 16-pin QSOP, as well as a 14-pin SO.
