Part Number: DRV8306
The following two signals are the control signal PWM and the A-phase voltage waveform. As shown in the figure, the yellow signal refers to the A-phase voltage waveform, which is A trapezoidal wave. The other green signal represents…
Part Number: OPA187 Other Parts Discussed in Thread: DAC80501 , , ADS1220 , OPA191 , OPA192 您好:
目前通过DAC80501输出DAC到OPA187(6倍放大)输出1-28V,测量1-28V纹波为4.8mV-7.0m,OPA电源为 LM2 7 3 3 X M F升压30V供电(测量纹波7.8mV),使用ADS1220采集1-28V电压,请问有什么办法可以让OPA输出纹波降到1mV左右吗?
LM2733XMF升压30V在增加一级LDO给OPA供电是不是会更好…
