Overview
The LM293DMR2G is a dual independent precision voltage comparator manufactured by onsemi, housed in an 8-lead Micro8 surface-mount package. It supports single supply operation from 2.0 Vdc to 36 Vdc or split supplies of ±1.0 Vdc to ±18 Vdc. The device features a low input bias current of 25 nA and a maximum input offset voltage of 5.0 mV. It operates within a temperature range of -25°C to +85°C with a typical power supply current of 0.4 mA.
Feature Summary
- Dual independent precision comparators designed for consumer, automotive, and industrial electronics
- Wide operating voltage range compatible with single or split supply configurations
- Low power consumption with current drain independent of supply voltage
- Open-collector outputs compatible with DTL, ECL, TTL, MOS, and CMOS logic levels
Applications
- Voltage monitoring systems
- Battery management circuits
- Motor control applications
- Power supply regulation
- Industrial automation sensors
Procurement Notes
Verify the specific ordering suffix 'DMR2G' corresponds to the Micro8 package and tape-and-reel shipping configuration. Confirm that the component meets RoHS compliance standards and lead-free requirements as specified in the manufacturer's documentation before finalizing procurement orders.
Selection Notes
Select this component when a dual-channel comparator with wide common-mode input range including ground is required. Ensure the application utilizes open-collector outputs with appropriate pull-up resistors. Verify that the operating temperature range of -25°C to +85°C aligns with the environmental conditions of the target system.
Part Context
This part belongs to the LMx93/LM2903 series of low offset voltage dual comparators. It shares functional similarities with the LM393 and LM2903 but is distinguished by its specific industrial temperature rating and Micro8 packaging format. The device is designed to replace older generation comparators in modern compact electronic designs.

FAQ
What is the input common mode voltage range?
The input common mode voltage range extends down to ground level (0 V) and up to VCC minus 1.5 V.
Can differential input voltages exceed the supply voltage?
Yes, differential input voltages may be larger than the supply voltage without damaging the comparator inputs, provided they do not go more negative than -0.3 V relative to ground.
