The onsemi LM2903DMR2G is a dual comparator designed for general-purpose voltage comparison applications, offering excellent precision and reliability across a wide range of operating conditions. It features an open-collector output and operates over a wide single-supply voltage range from 2.0 V to 36 V, or a split-supply range of ±1.0 V to ±18 V, providing flexibility for both low- and high-voltage system designs. With its very low current drain of only 0.4 mA, the LM2903DMR2G ensures energy-efficient operation even in battery-powered devices. The device exhibits a low input bias current of 25 nA, a low input offset current of 5 nA, and a maximum input offset voltage of 5 mV, ensuring high accuracy and stable performance in precision measurement and control applications.
Engineered for robustness and versatility, the LM2903DMR2G supports differential input voltage ranges equal to the power supply voltage and offers input common-mode capability down to ground level, allowing for accurate comparisons even at low voltages. Its output is compatible with multiple logic families, including DTL, ECL, TTL, MOS, and CMOS, enabling easy interfacing with a wide variety of digital systems. Integrated ESD protection clamps on the inputs enhance durability and safeguard against electrostatic damage without compromising electrical performance. Packaged in a compact 8-pin MSOP, the LM2903DMR2G is ideal for space-limited applications such as automotive systems, power management, instrumentation, and consumer electronics.
