High-Efficiency, 1.5MHz
Op Amps with RRIO
MAX9617/MAX9618
General Description
The MAX9617/MAX9618 are low-power, zero-drift opera-
tional amplifiers, designed for use in portable consumer,
medical, and industrial applications.
The MAX9617/MAX9618 feature rail-to-rail CMOS inputs
and outputs, a 1.5MHz GBW at just 59FA supply current
and 10FV (max) zero-drift input offset voltage over time
and temperature. The zero-drift feature of the MAX9617/
MAX9618 reduces the high 1/f noise typically found in
CMOS input operational amplifiers, making it useful for a
wide variety of low-frequency measurement applications.
The MAX9617 is available in a space-saving, 2mm x
2mm, 6-pin SC70 package. The MAX9618 is available
in a 2mm x 2mm, 8-pin SC70 package. All devices are
specified over the -40NC to +125NC automotive operating
temperature range.
