TC7650 CMOS斩波稳定的运算放大器实际上从系统误差计算中消除了失调电压误差项。例如,最大VOS规格5uV代表比行业标准OP07E改进了15倍。 50 nV /°C的偏移漂移指标比OP07E低25倍以上。更高的性能消除了VOS调整程序,定期调节电位器以及因修剪器损坏而引起的可靠性问题。无需额外的制造复杂性和激光或“齐纳扎普” VOS修整技术所带来的成本,即可获得TC7650的性能优势。 TC7650归零方案会随温度校正DC VOS误差和VOS漂移误差。零位放大器交替校正其自身的VOS错误和主放大器的VOS错误。失调调零电压存储在两个用户提供的外部电容器上。电容器连接到内部放大器的VOS空点。主放大器的输入信号从不切换。 TC7650输出上没有开关尖峰。 14引脚双列直插式封装(DIP)具有外部振荡器输入,以驱动调零电路以实现最佳噪声性能。 8引脚和14引脚DIP均具有输出电压钳位电路,以最大程度地减少过载恢复时间。
