All these comparators weredesigned specifically to operate from a singlepower supply over a wide range of voltages.Operation from split power supplies is alsopossible. These comparators also have a uniquecharacteristic in that the common-mhttp://doc.xuehai.net/b9bcc8a4eaeecbb1161a2b152.htmlodevoltage includes ground even thoughoperated from a single power supply voltage.

At output switch point, VO ≈ 1.4V, RS = 0 with VCC from 5V to 30V, and over the full input common-mode range (0V to VCC –1.5V).2.The direction of the input current is out of the IC due to the PNP input stage. This current is essentially constant, independent of the state of the output, so no loading charge exists on the reference of input lines3.The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is VCC or both inputs can go to –1.5V, but either 30V without damage.4.The response time specified is for a 100mV input step with 5mV overdrive. 5.Positive excursions of input voltage may exceed the power supply lhttp://doc.xuehai.net/b9bcc8a4eaeecbb1161a2b152.htmlevel. As long as the other voltage remains within the common-mode range, the comparator will provide a proper output state. The low input voltage state must not be less than –0.3V (or 0.3V bellow the negative power supply, if used)6.Maximum values are guaranteed by design. 4/7 LM2901H Electrical Characteristics 文档下载 免费文档下载 http://doc.xuehai.net/ Figure 5.
