NJM2737
Low Noise Low Supply Voltage Dual Operational Amplifier
with Full Swing Input and Output
s
GENERAL DESCRIPTION
NJM2737 is a single supply dual operational amplifier with
full swing input and output, operates from 1.8V.
Noise characteristic is designed low as conventional low
noise operational amplifiers, such as NJM5532 and NJM4580.
It is suitable for PC audio, portable audio and other low
voltage single supplied audio applications.
