NJM2737
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 1.8V with a 5nV/√Hz
low noise of the conventional low noise operational
amplifiers such as the NJM4580 and NJM 5532.
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 (TVSP).
