MAX9617–MAX9620
Single/Dual SC70, Zero-Drift,
High-Efficiency, 1.5MHz Op Amps with RRIO
General Description
The MAX9617–MAX9620 are low-power, zero-drift oper-
ational amplifiers available in space-saving SC70 pack-
ages. They are designed for use in portable consumer,
medical, and industrial applications.
The MAX9617–MAX9620 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 reduces the high
1/f noise typically found in CMOS input operational ampli-
fiers, making it useful for a wide variety of low-frequency
measurement applications.
The MAX9617 and MAX9619 are available in a space-
saving, 2mm x 2mm, 6-pin SC70 package. The MAX9619
features a power-saving shutdown mode. The MAX9618
is available in a 2mm x 2mm, 8-pin SC70 package. The
MAX9620 is available in a 2mm x 2mm, 5-pin SC70
package. All devices are specified over the -40NC to
+125NC automotive operating temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
