Dual CMOS Single-Supply Rail-to-Rail Input/Output Operational Amplifier

The OP250 and OP450 are dual and quad CMOS single-supply, amplifiers featuring rail-to-rail inputs and outputs. Both are guaranteed 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 enables designers to build multistage filters in single-supply systems and maintain high signal-to-noise ratios.

The OP250 and OP450 are specified over the extended indus-14- 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-–IN line (TSSOP) and narrow 14-lead SO packages.
