OP490GP Micro-power Quad Op-Amp

Contents hide

OP490 is a Micropower quad op-amp IC. OP490 is a high-performance micropower quad op-amp that operates from a single supply of +1.6 V to +36 V or from dual supplies of ±0.8 V to ±18 V. Input voltage range includes the negative rail allowing the OP490 to accommodate input signals down to the ground in single-supply operation. The OP490’s output swing also includes ground when operating from a single supply, enabling “zero-in, zero-out” operation.

Operational Amplifier

An operational amplifier or op-amp is simply an electronic linear Integrated Circuit or IC that has multiple terminals. An op-amp is a voltage amplifying device that is meant to be work with external feedback components such as resistors and capacitors. Operational amplifiers are considered to be one of the most vastly used electronic component, with applications ranging from small scale consumer electronic components such as smartphones, tablets, PCs, to large scale industrial instrumentation tools such as poisonous gas sensors and transducers for impurity detection.

Application

BATTERY-POWERED APPLICATIONS

The OP490 can be operated on a minimum supply voltage of +1.6 V, or with dual supplies of ±0.8 V, and draws only 60 µA of supply current. In many battery-powered circuits, the OP490 can be continuously operated for hundreds of hours before requiring battery replacement, reducing equipment downtime and operating costs.
