LM2902/ LM2902A/ LM2904/ LM2904A
DUAL AND QUAD OPERATIONAL AMPLIFIERS
Description
The LM2902/2904 series amplifiers consist of four and two
independent high-gain operational amplifiers with very low input offset
voltage specification. They have been designed to operate from a
single power supply over a wide range of voltages; however operation
from split power supplies is also possible. They offer low power
supply current independent of the magnitude of the power supply
voltage.
The LM2902/2904 series are characterized for operation from
-40℃ to +125℃ and the dual devices are available in SO-8, MSOP-8,
TSSOP-8 and the quad devices available in SO-14 and TSSOP-14
with industry standard pin-outs. Both use green mold compound as
standard.
