SM73302
August 16, 2011
88 MHz, Precision, Low Noise, 1.8V CMOS Input,
Decompensated Operational Amplifier
General Description
The SM73302 low noise, CMOS input operational amplifier
offers a low input voltage noise density of 5.8 nV/ while
consuming only 1.15 mA of quiescent current. The SM73302
is stable at a gain of 10 and has a gain bandwidth (GBW)
product of 88 MHz. The SM73302 has a supply voltage range
of 1.8V to 5.5V and can operate from a single supply. The
SM73302 features a rail-to-rail output stage, and is part of the
precision amplifier family and is ideal for a variety of instru-
mentation applications.
The SM73302 provides optimal performance in low voltage
and low noise systems. A CMOS input stage, with typical input
bias currents in the range of a few femtoamperes, and an in-
put common mode voltage range, which includes ground,
makes the SM73302 ideal for low power sensor applications
where high speeds are needed.
The SM73302 is manufactured using National’s advanced
VIP50 process. The SM73302 is offered in a 5-Pin SOT-23
package.
