General Description

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 or with a single supply of +4.5V to

+11V. These op amps provide a unity-gain bandwidth

of 5MHz with only 770µA of quiescent current 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

= 100kΩ) of either rail.

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.
