The OP290 is a high performance micropower dual operational amplifier that operates from a single or dual power supply. It has features such as low power consumption, high output drive, low input offset voltage, and high open-loop gain.
The OP290 dual operational amplifier operates from a single supply of 1.6 V to 36 V or dual supplies of ±0.8 V to ±18 V. It features low quiescent current (<20 µA per amplifier), high output drive (>5 mA), low input offset voltage (<200 µV) and high open‑loop gain (>400 V/mV). The device is suited for battery‑powered and portable applications.
The datasheet provides detailed specifications, pin connections for the 8‑lead PDIP package, absolute maximum ratings, typical performance curves, and application circuits such as temperature‑to‑current transmitters, variable slew‑rate filters, and low‑overhead voltage references.
