DESCRIPTION
The UTC LV324 is a quad op amp with low supply current and
low voltage (2.7~5.5V). It brings nice performance to low voltage and
low power systems. With a 1MHz unity-gain frequency. The UTC
LV324 has a guaranteed 1V//μs slew rate and low supply current. It
provides heavy rail-to-rail (R-to-R) output swing loads and the input
common-mode voltage range including ground. Besides, it is also
capable for comfortably driving large capacitive loads.
The UTC LV324 has bipolar input and CMOS output for
improved noise performance and higher output current drive. It’s the
most cost effective solution for the applications where low voltage
operation, space saving and low price are required.


Notes: 4. The maximum power dissipation is a function of TJ(MAX), θJA. The maximum allowable power dissipation at
any ambient temperature is PD=(TJ(MAX)-TA)/ θJA. All numbers apply for packages soldered directly onto a
PC Board.
5. Typical values represent the most likely parametric norm as determined at the time of characterization.
Actual typical values may vary over time and will also depend on the application and configuration. The
typical values are not tested and are not guaranteed on shipped production material.
6. All limits are guaranteed by testing or statistical analysis.
7. RL is connected to V-. The output voltage is 0.5V≤VO≤4.5V.
8. Connected as voltage follower with 3V step input. Number specified is the slower of the positive and
negative slew rates.
