The LM339DR2G is a single-supply quad comparator manufactured by onsemi, housed in a SOIC-14 package. It operates within a power supply voltage range of 3.0 V to 36 V or split supplies from ±1.5 V to ±18 V. The device features low input bias current (typical 25 nA) and low input offset voltage (typical ±2.0 mV). Electrical characteristics include a response time of 1.3 µs, an output sink current capability of 16 mA, and a saturation voltage of 130 mV at 4.0 mA. The operating temperature range spans from -25 °C to +85 °C.
Verify the specific suffix DR2G indicates the SOIC-14 package and tape & reel shipping configuration. Confirm that the component meets RoHS compliance standards and is lead-free. Ensure the operating temperature range aligns with system requirements, as this variant supports -25 °C to +85 °C. Check for any automotive-specific prefixes if AEC-Q100 qualification is required.
Select this component when multiple independent comparators are needed in a single package. It is suitable for designs requiring compatibility with standard logic families. Consider the open-collector output structure for interfacing with various voltage levels. Evaluate the low input bias current requirement against other available options in the LM339 family.
This part belongs to the LM339 family of single-supply quad comparators. It shares functional similarities with the LM239, LM2901, and MC3302 devices. The LM339 series is widely used in consumer, automotive, and industrial electronics. The DR2G suffix specifically denotes the surface-mount SOIC-14 package format.
