OPA317-Q1シリーズのCMOSオペアンプは、求めやすい価格でありながら高精度の性能を実現します。これらのデバイスは、ゼロドリフト・ファミリのアンプのメンバーで、専用の自動較正技術を使用して、低いオフセット電圧(最大90μV)、時間と温度に対してゼロに近いドリフト、わずか35μA (最大値)の静止電流を同時に実現しています。
OPA317-Q1ファミリは、レール・ツー・レールの入出力に加えて、フラットに近い1/fノイズが特長で、多くのアプリケーションに理想的なアンプであり、システムの設計に簡単に組み込めます。これらのデバイスは、最小1.8V (±0.9V)、最大5.5V (±2.75V)の低電圧での動作に最適化されています。
OPA317-Q1 (シングル・バージョン)はSOT23-5パッケージで利用可能です。OPA2317-Q1 (デュアル・バージョン)はVSSOP-8パッケージで利用可能です。OPA4317-Q1はTSSOP-14パッケージで利用可能です。どのバージョンも、-40℃~+125℃での動作が保証されています。
