GENERAL DESCRIPTION

The 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.

These 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.

The 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.

The OP250 and OP450 are specified over the extended indus-

trial (–40

°C to +125°C) temperature range. The OP250, dual,

is available in 8-lead TSSOP and SO surface mount packages.

The OP450, quad, is available in 14-lead thin shrink small out-

line (TSSOP) and narrow 14-lead SO packages.
