NJM2737 Low Noise, Rail-to-Rail Input/Output Dual Operational Amplifier GENERAL DESCRIPTION PACKAGE OUTLINE The NJM2737 is a Rail-to-Rail Input/Output single supply dual operational amplifier featuring low voltage operation, low power and low noise. It is designed to offer a low voltage operating from 1.8V with a 5nV/ Hz low noise of the conventional low noise operational NJM2737D NJM2737M amplifiers such as the NJM4580 and NJM 5532. (DIP8) (DMP8) The Combination of Rail-to-Rail Input/Output, low voltage operation and low noise makes the NJM2737 well-suited for single supply low voltage operation applications such as PC audio, portable audio and others. The NJM2737 is available in a wide variety NJM2737V NJM2737RB1 packages 8-lead DIP, and 8-lead surface-mount (SSOP8) (MSOP8 (TVSP8)) packages of SOP (DMP), SSOP and MSOP (TVSP).
