MAX9617–MAX9620

EVALUATION KIT AVAILABLE

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.

MAX9617–MAX9620 Single/Dual SC70, Zero-Drift, High-Efficiency, 1.5MHz Op Amps with RRIO Power Supplies and Layout The MAX9617–MAX9620 operate either with a single supply from +1.6V to +5.5V with respect to ground or with dual supplies from Q0.8V to Q2.75V. When used with dual supplies, bypass both supplies with their own 0.1FF capacitor to ground. When used with a single supply, bypass VDD with a 0.1FF capacitor to ground.
