单路、低失调电压 (0.06mV)、低噪声、低偏置电流、成本优化型、RRIO、e-trim™ 运算放大器

OPAx397 系列运算放大器（OPA397、OPA2397 和 OPA4397）具有超低失调电压、温漂以及输入偏置电流，可提供轨至轨输入和输出操作。除了精密直流精度，交流性能经优化可实现低噪声和快速稳定的瞬态响应。得益于这些特性，OPAx397 成为驱动高精度模数转换器 (ADC) 或缓冲高分辨率数模转换器 (DAC) 输出的理想选择。\n\nOPAx397 采用 TI 的 e-trim™ 运算放大器技术，无需任何输入斩波或自动置零技术，即可实现超低失调电压以及失调电压温漂。此项技术可针对传感器输入或光电二极管电流至电压测量实现超低输入偏置电流，从而为光学模块或医疗仪表创建高性能跨阻级。 • 低失调电压：±60µV（最大值）\n• 低温漂：±0.18µV/°C\n• 低输入偏置电流：10fA\n• 低噪声：10kHz 时为 4.4 nV√Hz \n• 低 1/f 噪声：2µVPP（0.1Hz 至 10Hz）\n• 低电源电压运行范围：1.7 V 至 5.5 V\n• 低静态电流：1.22mA\n• 快速稳定：0.75µs（1V，0.1%）\n• 快速压摆率：4.5 V/µs\n• 高输出电流：+65/–55mA 短路\n• 增益带宽：13MHz\n• 轨至轨输入和输出\n• 额定温度范围：–40°C 至 +125°C\n• EMI/RFI 滤波输入;
