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 and the
quad devices available in SO-14 and TSSOP-14 with industry
standard pin-outs. Both use green mold compound as standard.
Features
 Wide power supply voltage range:
 Single supply: 3V to 36V
 Dual supplies: ±1.5V to ±18V
 Very low supply current drain
 LM2904 500µA – independent of supply voltage
 LM2902 700µA – independent of supply voltage
 Low input bias current: 20nA
 Low Input offset voltage:
 A Versions …1mV (Typ)
 Non-A Version…2mV(Typ.)
 Large DC voltage gain: 100dB
 Wide bandwidth (unity gain): 700KHz (temperature
compensated)
 Internally compensated with unity gain.
 Input common-mode voltage range includes ground
 Differential input voltage range equal to the power supply voltage
 Large output voltage swing: 0V to V
CC
-1.5V
 SO-8(duals) and SO-14/TSSOP-14(quads) packages available
 Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2)
 Halogen and Antimony Free. “Green” Device (Note 3)
