UNISONIC TECHNOLOGIES CO., LTD SINGLE GENERAL PURPOSE, LOW VOLTAGE, RAIL-TO-RAIL OUTPUT OPERATIONAL AMPLIFIER DESCRIPTION The UTC LV321 is a single op amp with low supply current. It brings good performance in low voltage, low power operating systems. The UTC LV321 has a guaranteed.8v/µs slew rate and a 1MHz unity-gain bandwidth, in 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. FEATURES * 2.7V and 5V Performance Guaranteed * No Crossover Distortion * 13µA Low Supply Current * Rail-to-Rail Output Swing @1kΩ Load: V + -25mV V - +15mV * V CM From -.2V to V + -.8V ORDERING INFORMATION Ordering Number Lead Free Halogen Free Package Packing LV321L-AF5-R LV321G-AF5-R SOT-25 Tape Reel LV321L-AF5-A-R LV321G-AF5-A-R SOT-25 Tape Reel LV321L-AL5-R LV321G-AL5-R SOT-353 Tape Reel 1of 1 Copyright 218 Unisonic Technologies Co., Ltd QW-R15-36.E
