LM2903
Low-power dual voltage comparator
Related products
Description
This device consists of two independent low-power voltage comparators designed specifically to operate from a single supply over a wide range of voltages. Operation from split power supplies is also possible.
In addition, the device has a unique characteristic in that the input common-mode voltage range includes the negative rail even though operated from a single power supply voltage.

LM2903
低功耗雙通道電壓比較器
產品描述
LM2903 為雙通道低功耗電壓比較器，專為單一電源供應設計，可在寬範圍電壓下運作，亦可支援雙電源模式。其獨特特性使輸入共模電壓範圍包含負電源軌，即使在單電源供應下運作亦適用。
特性
- 寬範圍供應電壓：單電源 +2V 至 +36V，或雙電源 ±1V 至 ±18V
- 極低功耗：獨立於供應電壓，每通道僅 0.4mA（+5V 時每比較器功耗 1mW）
- 低輸入偏置電流：典型值 25nA
- 低輸入偏移電流：典型值 ±5nA
- 輸入共模電壓範圍 包含負電源軌
- 低輸出飽和電壓：典型值 250mV（IO = 4mA）
- 差動輸入電壓範圍 等於供應電壓
- 相容於多種邏輯電路（TTL、DTL、ECL、MOS、CMOS）
- 符合車規認證
