Globaltech GS321
Low Power Single Operational Amplifiers
Product Description
The GS321 brings performance and economy to
low power systems.
With a high unity gain frequency and a guaranteed
0.4V/μs slew rate, the quiescent current is only
430μA/amplifier (5V).
The input common mode range includes ground
and therefore the device is able to operate in
single supply applications as well as in dual supply
applications. It is also capable of comfortably
driving large capacitive loads.
The GS321 is available in the SOT-23-5L
package. Overall the GS321 is a low power, wide
supply range performance op amp that can be
designed into a wide range of applications at an
economical price without sacrificing valuable board
space.

Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.
Operating Ratings indicate conditions for which the device is intended to be functional, but specific
performance is not guaranteed. For guaranteed specifications and the test conditions, see the
Electrical Characteristics.
