NJM2730 Rail-to-Rail Input/Output Single Operational Amplifier ■ GENERAL DESCRIPTION NJM2730 is a Rail-to-Rail Input/Output single operational amplifier featuring Low power, low noise and operation from 1.8V. Rail-to-Rail Input/Output provides wide dynamic range, is from ground to power supply level. In addition to ground sensing applications, NJM2730 enable to be applied to Hi-side sensing applications. The features are low noise and high phase margin for battery management, portable audio applications, and others. Furthermore NJM2730 is packaged with small size package SOT−23−5 ■ FEATURES ● Single Supply ● Operating Voltage ● Rail-to-Rail Input ● Rail-to-Rail Output ● Load Drivability ● Offset Voltage ● Slew Rate ● Low Input Voltage Noise ● Adequate phase margin ● Bipolar Technology ● Package Outline ■ PACKAGE OUTLINE NJM2730F 1.8 to 5.0V VICM= 0 to 5.0V at V+=5V VOH ≥ 4.9V/ VOL ≤ 0.1V at V+=5V,RL=20kΩ VOH ≥ 4.75V/ VOL ≤ 0.25V at V+=5V,RL=2kΩ 5mV max 0.4V/µs typ. 10nV/√Hz typ.
