UNISONIC TECHNOLOGIES CO., LTD LV321 LINEAR INTEGRATED CIRCUIT SINGLE GENERAL PURPOSE, LOW VOLTAGE, RAIL-TO-RAIL OUTPUT OPERATIONAL AMPLIFIER DESCRIPTION The UTC LV321 is a single op amp with low supply current and low voltage (2.7-5.5V) well economic consideration. It brings nice performance and to low voltage, low power systems. With a 1MHz unity-gain frequency, The UTC LV321 has a guaranteed 1 V/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 LV321 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.
