概述

Description

LM393EDR2G is TI’s dual voltage comparator in an 8-pin package with open-collector outputs. It compares two input voltages on each channel and sinks current on the corresponding output when the non-inverting input exceeds the inverting input (and vice versa). Outputs require pull-up resistors to a positive supply. Key points:
- Wide supply range: roughly 2–36 V
- Input common-mode includes ground but does not reach Vcc (typically up to Vcc−1.5 V)
- Open-collector outputs: both channels can be used independently
- Pinout (typical SOIC/DIP layout): 1 Output A, 2 In− A, 3 In+ A, 4 GND, 5 In+ B, 6 In− B, 7 Output B, 8 Vcc
- Common uses: zero-cross/digital threshold sensing, level shifting, battery monitoring, PWM/threshold detectors
- EDR2G denotes a specific RoHS-compliant package variant (8‑pin)
Tip: add pull-ups and consider input bias currents and propagation delay in your design.

Features

Here are the main features of LM393EDR2G:
- Dual, independent voltage comparators
- Open-collector outputs (per channel) with external pull-up resistors
- Wide supply voltage range: typically 2 to 36 V
- Input common-mode range includes ground (0 V) up to about Vcc–1.5 V
- Outputs can sink significant current (pull-down capability via open-collector)
- Low-power operation
- Industrial temperature range: -40°C to +125°C
- 8-pin package (SOP/SOIC variants; EDR2G indicates specific packaging/reeling)
- Suitable for applications like zero-crossing, level shifting, window comparators, and general comparator tasks
Note: Always check the latest datasheet for exact electrical specs and packaging details.

Package

8-pin small‑outline package (SOIC-8), RoHS‑compliant (green).

Pinout

- Pin count: 8 pins (8-pin package)
- Function: Dual voltage comparator with open-collector outputs (two independent comparators; outputs require pull-up resistors).

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: An American multinational semiconductor company that designs and manufactures analog and embedded processing ICs; one of the world’s largest semiconductor makers.

Application

LM393EDR2G is a dual low-power comparator with open-collector outputs. Common applications:
- Battery and power-supply monitoring (undervoltage/overvoltage)
- Level detection and threshold switching
- Window comparators and zero-cross detectors
- Sensor conditioning (thermistors, photo sensors) with reference
- PWM control, motor feedback, and alarm circuits
- Hysteresis generation for clean switching in simple control circuits

Equivalent

Common equivalents to LM393EDR2G (dual, open-collector comparator) include:
- LM2903 (dual comparator)
- LM393N / LM393DR2G (same device in different packaging)
- LMV393 (low-voltage version)
Other vendors often offer cross-refs to TI’s LM393 (e.g., Onsemi LM393N). Always check input common‑mode range, supply voltage, and output sinking current to ensure a drop-in replacement.
