The MAX402/MAX403/MAX438/MAX439 micropower op
amps combine high-speed performance with low-power
operation. The MAX402/MAX403 are compensated for
unity-gain stability, while the MAX438/MAX439 are com-
pensated for stability in applications with a closed-loop

gain (A ) of 5V/V or greater.
VCL
♦ 10MHz Unity-Gain Bandwidth
♦ 40V/µs Slew Rate
The MAX402/MAX438 require less than 75µA of supply
current while delivering 2MHz bandwidth with 6V/µs
slew rate (MAX402), and 6MHz gain bandwidth with
10V/µs slew rate (MAX438).
♦ 375µA Max Supply Current
MAX438
For a p p lic a tions re q uiring inc re a s e d s p e e d , the
MAX403/MAX439 consume less than 375µA of supply
current while delivering 10MHz gain bandwidth with
40V/µs slew rate (MAX403), and 25MHz gain bandwidth
with 48V/µs slew rate (MAX439).
