【选型】TI低失真运放OPA2350与国产低噪声运放TP230X在通用伺服和机器臂伺服性能优势对比
在工业伺服、电梯、机械人手臂等需要电机高精度信号采样领域，一般会需要更低失真、更高增益带宽、更高转换速率的单电源轨至轨运算放大器做采样信号放大，以保证电流环能够快速且正确的工作。目前有很多公司选用了TI-低失真运放-OPA2350系列。现在，国产3PEAK公司研发的低噪声TP230X系列运放可以在通用伺服和机器臂伺服上较好的替换该产品。
两者主要性能参数对比如下：
PN | OPA2350UA | TP2302-SR |
Vendor | TI | 3PEAK |
测试环境 | Vs=+5V,T=+25℃ | Vs=+5V,T=+25℃ |
输入失调电压（TYP） | 150uV | 7uV |
失调电压温飘 | 4uV/℃ | 1uV/℃ |
增益带宽积 | 38MHz | 20MHz |
压摆率 | 22V/us | 25V/us |
电源抑制比 | 130dB | 100dB |
共模抑制比 | 84dB | 100dB |
等效输入噪声 | 7nV/√hz（f=10khz） | 7.3nV/√hz（f=1khz） |
最大电流输出 | 80mA | 130mA |
参数对比分析：
1. 输入失调电压：TP2303-SR有着较为明显的优势，尤其是在放大增益较大时，将会有较大的差异，但如果只是作为跟随，两者都完全满足工程需求；
2. 失调电压温飘：TP2303-SR有较高的温度稳定性，更适合高低温环境和高可靠性要求；
3. 增益带宽积：OPA2350UA更有优势，这个优势主要体现在高频段，实际伺服和机器人的检测应用中，采样频率不会超过20khz。往往还会增加RC滤波限制高频信号。所以二者都符合设计需求。
4. 电源抑制比：两者的电源抑制比都很高，在5V单电源供电的设计中，没有什么差异；
5. 共模抑制比：TP2303-SR可能会在热地方案中有一些优势，可以屏蔽一些高压母线共模干扰；
6. 等效输入噪声：两者表现都非常优异，完全满足需求；
7. 电流输出能力：TP2303-SR有一定优势，目前MCU内自带的ADC输入阻抗不是很稳定，所以运放的电流输出能力越高则测量精度越高。
PS：在使用这类高精度运放时，建议反馈电阻选用1/1000精度甚至更高等级，才能较好的发挥出高精度运放的性能。

【产品】失调电压仅15μV的高电源电压放大器TPA186x系列，支持4.5V至36V供电，增益带宽积6MHz
TPA1861/TPA1862/TPA1864系列是思瑞浦推出的最新高电源电压放大器，分别为单通道、双通道和四通道，具有15μV的低失调电压、低噪声和稳定的高频响应，采用了思瑞浦的专有技术和专利设计技术，在单放大器仅消耗2000μA静态电流情况下，可获得12MHz的带宽。
项目中需要找一颗低噪声运放，替换AD8646ARZ，之前找过一颗国产的，但测试中出现电机停顿，估计是电机启动时电压电流跳变时响应不够快，原来的AD8646ARZ是没问题的，麻烦推荐一下合适的替换料吗？
这边给您推荐思瑞浦的TP2302-SR，带宽为20Mhz 转换效率为25v/us,而ADI的AD8646ARZ 带宽24Mhz 转换效率11v/us，参数性能上相符，应该能解决您电机停顿的问题，数据手册为https://www.sekorm.com/doc/3318493.html。可申请样品测试一下
【产品】180V/μs转换率的国产高速运放TPH250X系列，增益带宽250MHz
思瑞普微电子推出的高速运放TPH250X系列，250MHz增益带宽，180V/μs转换率，6.5nv/√hz的低噪声电压。高带宽、高转换率、低功耗和低噪声是低电压高速信号系统的理想选择。
