T he OP250 and OP450 are dual and quad CMOS single-supply,
amplifiers featuring rail-to-rail inputs and outputs. Both are guar-
anteed to operate from a +2.7 V to +5 V single supply.
T hese amplifiers have very low input bias currents. Outputs are
capable of driving 100 mA loads and are stable with capacitive
loads. Supply current is less than 1 mA per amplifier.
Applications for these amplifiers include portable medical
equipment, safety and security, and interface to transducers
with high output impedance.
T he ability to swing rail-to-rail at both the input and output en-
ables designers to build multistage filters in single-supply sys-
tems and maintain high signal-to-noise ratios.
T he OP250 and OP450 are specified over the extended indus-
trial (–40
°
C to +125
°
C) temperature range. T he OP250, dual,
is available in 8-lead T SSOP and SO surface mount packages.
T he OP450, quad, is available in 14-lead thin shrink small out-
line (T SSOP) and narrow 14-lead SO packages.
