Single Low Voltage Rail- to-Rail Output Operational Amplifier
Product Description
Features
The GSV321 is the single-amplifier version, the
most cost-effective solutions for applications
where low-voltage operation, space saving, and
low price are needed. And offer specifications that
meet or exceed. It is devices have rail-to-rail
output-swing
capability,
and
the
input
common-mode voltage range includes ground.
It is exhibit excellent speed-to-power ratios,
achieving 1MHz of bandwidth at 1V/ms slew rate
with low supply current.
This package saves space on printed circuit
boards and enables the design of small portable
electronic devices. It also allows the designer to
place the device closer to the signal source to
reduce noise pickup and increase signal integrity.
The GSV321 devices characterized for operation
from –40°C to 85°C.

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 under “recommended
operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device
reliability.
All voltage values(except differential voltages and VCC specified for the measurement of IOS) are with respect to the
Note 1:
network GND.
Note 2:
Differential voltages are at IN+ with respect to IN-.
Note 3:
Short circuits from outputs to VCC can cause excessive heating and eventual destruction.
Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any
Note 4:
allowable ambient temperature is PD = (TJ(max) - TA) / θJA. Selecting the maximum of 150ºC can impact reliability.
The package thermal impedance is calculated in accordance with JESD51.
