High-speed characteristics of slew rate(SR=9V/us) and bandwidth (GBW=5MHz), low input bias current (IB=1pA typ.) and wide temperature range(Ta=−40℃ to 125℃) makes NJU7046 especially suitable for sensors and filters application for industrial, buffers of input and output for ADC, DAC, ASIC and other wide output swing devices. In addition to the NJU7046F3 is available in the ultra-small SC88A package. This package saves space on print circuit boards and enables the design of Battery-powered instruments. ■PACKAGE OUTLINE PIN FUNCTION 1 5 2: VSS 3: +INPUT 2 3 1: OUTPUT 4 4: -INPUT NJU7046F (SOT−23−5) NJU7046F3 (SC88A) 5: VDD SOT−23−5 , SC88A (Top View) Ver 01 -1- NJU7046 ■ABSOLUTE MAXIMUM RATINGS(Ta=25℃ unless otherwise noted.)
