1 UNISONIC TECHNOLOGIES CO., LTD GENERAL PURPOSE, LOW VOLTAGE, RAIL-TO-RAIL OUTPUT OPERATIONAL AMPLIFIERS DESCRIPTION The UTC LV358 is a dual op amp with low supply current and low voltage ( V). It brings nice performance to low voltage and low power systems. With a 1MHz unity-gain frequency. The UTC LV358 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 LV358 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 * 21µA Low Supply Current * Rail-to-Rail Output Load V + -1mV V - +65mV * V CM From -.2V to V + -.8V ORDERING INFORMATION Ordering Number Package Packing LV358G-S8-R SOP-8 Tape Reel LV358G-SM1-R MSOP-8 Tape Reel LV358G-P8-R TSSOP-8 Tape Reel LV358G-K8-23-R DFN-8(2 3) Tape Reel 1 of 11 Copyright 215 Unisonic Technologies Co., Ltd
