The LM293DR2G is a dual independent precision voltage comparator manufactured by onsemi, designed for single or split supply operation. It operates within a wide power supply range of 2.0 Vdc to 36 Vdc (±1.0 Vdc to ±18 Vdc). The device features very low current drain of 0.4 mA, independent of supply voltage, and low input bias current of 25 nA. Input offset voltage is specified at a maximum of 5.0 mV. The output is compatible with DTL, ECL, TTL, MOS, and CMOS logic levels. It is housed in an SOIC-8 package and supports an operating temperature range of -25 °C to +85 °C.
Verify the ordering suffix DR2G corresponds to the SOIC-8 Tape & Reel packaging configuration. Confirm the specific device code matches the LM293 series requirements for the intended industrial temperature range. Ensure compliance with Pb-Free and RoHS standards as documented in the manufacturer's specifications.
Select this component when high gain and wide bandwidth are required for precise voltage comparison tasks. Consider the open-collector output structure which necessitates external pull-up resistors for proper logic level interfacing. Evaluate the low input bias current characteristics for high-impedance sensor interfaces.
This part belongs to the LMx93/LM2903 series of dual comparators from onsemi. It shares architectural similarities with the LM393 and LM2903 but is optimized for the industrial temperature grade (-25 °C to +85 °C). The series is known for its robustness and low power consumption in general-purpose analog switching applications.
