Description

The UPC339 is a quad comparator which is designed to operate from a single power supply over a wide range of voltage. Operation from split power supplies, is also possible and the power supply current drain is very low. Further advantage, the input common-mode voltage includes ground, even though operated from a single power supply voltage.

Part Number: LM2903D

Function: Dual Differential Comparator

Package: SOIC 8 Pin type

Manufacturer: Texas Instruments

Pinouts:

Description

These devices consist of two independent voltage comparators that are designed to operate from a single power supply over a wide range of voltages. Operation from dual supplies also is possible as long as the difference between the two supplies is 2 V to
36 V, and VCC is at least 1.5 V more positive than the input common-mode voltage. Current drain is independent of the supply voltage. The outputs can be connected to other open-collector outputs to achieve wired-AND relationships.

The LM193 is characterized for operation from −55°C to 125°C. The LM293 and LM293A are characterized for operation from −25°C to 85°C. The LM393 and LM393A are characterized for operation from 0°C to 70°C. The LM2903 is characterized for operation
from −40°C to 125°C.

Features

1. Single Supply or Dual Supplies

2. Wide Range of Supply Voltage
(1) Max Rating: 2 V to 36 V
(2) Tested to 30 V: Non-V Devices
(3) Tested to 32 V: V-Suffix Devices

3. Low Supply-Current Drain Independent of Supply Voltage: 0.4 mA (Typ) Per Comparator

4. Low Input Bias Current: 25 nA (Typ)

5. Low Input Offset Current: 3 nA (Typ) (LM139)

6. Low Input Offset Voltage: 2 mV (Typ)

7. Common-Mode Input Voltage Range Includes Ground
