The MAX4245/MAX4246/MAX4247 family of low-cost
op amps offer rail-to-rail inputs and outputs, draw only
320µA of quiescent current, and operate from a single
+2.5V to +5.5V supply. For additional power conserva-
tion, the MAX4245/MAX4247 offer a low-power shutdown
mode that reduces supply current to 50nA, and puts the
amplifiers’ outputs in a high-impedance state. These
devices are unity-gain stable with a 1MHz gain-band-
width product driving capacitive loads up to 470pF.
The MAX4245/MAX4246/MAX4247 family is specified
from -40 C to +125°C, making them suitable for use in a
variety of harsh environments, such as automotive appli-
cations. The MAX4245 single amplifier is available in
ultra-small 6-pin SC70 and space-saving 6-pin SOT23
packages. The MAX4246 dual amplifier is available in
8-pin SOT23, SO, and µMAX
dual amplifier comes in a tiny 10-pin µMAX package.
