UNISONIC TECHNOLOGIES CO., LTD LV324 Preliminary CMOS IC GENERAL PURPOSE, LOW VOLTAGE, RAIL-TO-RAIL OUTPUT OPERATIONAL AMPLIFIERS 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.
