OLE
The OP150, OP250 and OP450 are single, dual and quad
CMOS single-supply, 4 MHz bandwidth amplifiers featuring
rail-to-rail inputs and outputs. All are guaranteed to operate from
a 3 volt single supply as well as a +5 volt supply.
The OP150 family of amplifiers have very low input bias currents. The outputs are capable of driving 250 mA loads and are
stable with capacitive loads as high as 500 pF.
Applications for these amplifiers include portable medical
equipment, safety and security, and interface for transducers
with high output impedances.
Supply current is only 600 µA per amplifier.
The ability to swing rail-to-rail at both the input and output enables designers to build multistage filters in single-supply systems and maintain high signal-to-noise ratios.
The OP150/OP250/OP450 are specified over the extended industrial (-40°C to +125°C) temperature range. The OP150
single amplifiers are available in 8-pin SO surface mount and
the 5-pin SOT23-5 packages. The OP250 dual is available in 8pin plastic DIPs and SO surface mount packages. The OP450
quad is available in 14-pin DIPs, TSSOP and narrow 14-pin SO
packages. Consult factory for TSSOP availability.
