| NJM2730 Low Supply Voltage Single Operational Amplifier with Full Swing Input and Output s GENERAL DESCRIPTION NJM2730 is a single supply single operational amplifier with full swing input and output, operates from 1.8V. Input and Output Full Swing 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 MTP-5. s PACKAGE OUTLINE NJM2730F s FEATURES q Single Supply q Operating Voltage q Input Full-Swing q Output Full-Swing q Load Drivability q Offset Voltage q Slew Rate q Low Input Voltage Noise q Adequate phase margin q Bipolar Technology q Package Outline s PIN CONFIGURATION 1.8 to 5.0V + VICM= 0 to 5.0V at V =5V + VOH 4.9V/ VOL 0.1V at V =5V,RL=20k + VOH 4.75V/ VOL 0.25V at V =5V,RL=2k 5mV max 0.4V/s typ. 10nV/Hz typ.
