Input Slew-Rate Requirements
As with all high-speed comparators, the high gain-bandwidth product of the MAX9201/MAX9202/ MAX9203 can create oscillation problems when the input traverses the linear region. For clean output switching without oscillation or steps in the output waveform, the input must meet minimum slew-rate requirements (0.5V/s typ). Oscillation is largely a function of board layout and of coupled source impedance and stray input capacitance. Both poor layout and large source impedance will cause the part to oscillate and increase the minimum slew-rate requirement. In some applications, it may be helpful to apply some positive feedback between the output and positive input. This pushes the output through the transition region clearly, but applies a hysteresis in threshold seen at the input terminals.

输入信号斜率要求:
和其他所有高速比较器一样,MAX9201/MAX9202/ MAX9203的高 增益-带宽 乘积会导致当输入信号穿越线性区域时产生震荡问题.如果想要输出没有震荡,输入必须满足最小信号斜率要求(0.5V/s 典型值).震荡大概是电路板布局、耦合阻抗和寄生电容的函数.所以这三个东西会影响最小信号斜率值.在某些时候给电路一个正反馈可以消除震荡,但是可能会引入延迟.
大意就是这个东西是个比较器,有 IN+ 和 IN- 两个输入,IN+ > IN-的时候输出就是高电压;IN+ < IN-的时候输出就是0.IN+ = IN-是分界线,这个时候芯片处于sb状态,必须赶快穿过这里,要求穿过这条线的时候变化率要快于0.5V/s,也有可能要更快一些
