LM339N Texas Instruments 模拟比较器 Quad Differential

1 Features 3 Description

The LMx39x and the LM2901xx devices consist of

1• Wide Supply Ranges

four independent voltage comparators that are

– Single Supply: 2 V to 36 V designed to operate from a single power supply over

(Tested to 30 V for Non-V Devices and a wide range of voltages. Operation from dual

32 V for V-Suffix Devices) supplies also is possible, as long as the difference

– Dual Supplies: ±1 V to ±18 V between the two supplies is 2 V to 36 V, and VCC is

at least 1.5 V more positive than the input common- (Tested to ±15 V for Non-V Devices and

mode voltage. Current drain is independent of the ±16 V for V-Suffix Devices)

supply voltage. The outputs can be connected to

• Low Supply-Current Drain Independent of other open-collector outputs to achieve wired-AND Supply Voltage: 0.8 mA (Typical) relationships.

• Low Input Bias Current: 25 nA (Typical) The LM139 and LM139A devices are characterized

• Low Input Offset Current: 3 nA (Typical) (LM139) for operation over the full military temperature range

• Low Input Offset Voltage: 2 mV (Typical) of –55°C to 125°C. The LM239 and LM239A devices

are characterized for operation from –25°C to 125°C. • Common-Mode Input Voltage Range

The LM339 and LM339A devices are characterized Includes Ground for operation from 0°C to 70°C. The LM2901,

• Differential Input Voltage Range Equal to LM2901AV, and LM2901V devices are characterized

Maximum-Rated Supply Voltage: ±36 V for operation from –40°C to 125°C.
