LP339N/NOPB 数据手册 - TI（德州仪器）
制造商:
TI（德州仪器）

比较器
封装:
PDIP-14
描述:
LP 系列低功耗比较器### 比较器，Texas InstrumentsTexas Instruments 系列电压比较器不仅包括传统单、双和四路比较器封装，还包括窗口比较器及过压和欠压监控器。 尽管比较器和运算放大器表面上是相似的设备，但它们在实用应用中的操作大大不同。 运算放大器适用于线性操作，附带适当反馈，而比较器定制用于快速切换且通常在开路模式中操作。 专用电压比较器具有明显较短的传播延迟，且可在饱和条件下具有更快的响应时间。 大多数比较器还更耐受高差分输入电压，且很多比较器具有开路集电极输出，从而可与其他设备并联操作。

Electrical Characteristics (Continued)
Note 9: Positive excursions of input voltage may exceed the power supply level.As long as the other voltage remains within the common-mode range, the compara-
tor will provide a proper output state. The low input voltage state must not be less than −0.3 V
DC
(or 0.3 V
DC
below the magnitude of the negative power supply, if
used) at T
A
=25˚C.
Note 10: At output switch point, V
O
=1.4V, R
S
=0Ω with V
+
from 5 V
DC
; and over the full input common-mode range (0 V
DC
to V
+
−1.5 V
DC
).
Note 11: For input signals that exceedV
+
, only the overdriven comparatoris affected. Witha 5V supply, V
IN
should be limited to 25Vmaximum, and a limiting resistor
should be used on all inputs that might exceed the positive supply.
Note 12: The output sink current is a function of the output voltage. The LP339 has a bi-modal output section which allows it to sink large currents via a Darlington
connection at output voltages greater than approximately 1.5 V
DC
and sink lower currents below this point. (See typical characteristics section and applications sec-
tion).
