NJM2737. Low Noise, Rail-to-Rail Input/Output Dual Operational Amplifier

Transcription

1 Low Noise, Rail-to-Rail Input/Output Dual Operational Amplifier GENERAL DESCRIPTION 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 1.8 with a 5n/ Hz low noise of the conventional low noise operational amplifiers such as the NJM458 and NJM 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 packages 8-lead DIP, and 8-lead surface-mount packages of SOP (DMP), SSOP and MSOP (TSP).
