双路、10MHz、CMOS、零漂移、零交叉、真 RRIO 精密运算放大器

OPAx388（OPA388、OPA2388 和 OPA4388）系列精密运算放大器是超低噪声、快速稳定、零漂移、零交叉器件，可实现轨至轨输入和输出运行。这些特性及出色的交流性能与仅为 0.25µV 的失调电压以及 0.005µV/°C 的温漂相结合，使得 OPAx388 成为驱动高精密模数转换器 (ADC) 或缓冲高分辨率数模转换器 (DAC) 输出的理想选择。该设计在驱动模数转换器 (ADC) 时具有出色的性能，而不会降低线性度。OPA388（单通道版本）提供 VSSOP-8、SOT23-5 和 SOIC-8 三种封装。OPA2388（双通道版本）提供 VSSOP-8 和 SO-8 两种封 • 超低失调电压：±0.25µV\n• 零交叉：140dB CMRR 真正 RRIO\n• 无 1/f 噪声：140nVPP（0.1Hz 至 10Hz）\n• 增益带宽：10MHz\n• 双电源：±1.25V 至 ±2.75V\n• EMI/RFI 滤波输入\n• 单通道电源版本采用 SOIC-8、SOT-23-5 和 VSSOP-8 封装\n• 四通道电源版本采用 SOIC-14 和 TSSOP-14 封装;
