The MAX4493/MAX4494/MAX4495 single/dual/quad

general-purpose operational amplifiers are designed

for use in systems powered with dual supplies from

±2.25V to ±5.5V. These op amps provide a unity-gain

bandwidth of 5MHz with only 770µA of quiescent cur-

rent per amplifier. The wide input common-mode range

extends from 200mV beyond the negative rail to within

1.5V of the positive supply rail while the output swings

within 10mV (R

These amplifiers have excellent (110dB) open-loop

gain with very low THD+N of 0.002% (f = 1kHz). The

single MAX4493 is available in a tiny 5-pin SC70 pack-

age and the dual MAX4494 is available in the space-

saving 8-pin SOT23. The quad MAX4495 is available in

both 14-pin TSSOP and 14-pin SO packages. All prod-

ucts are rated at the automotive temperature range of

-40°C to +125°C.
