Overview
The LM2901DR2G is a single-supply quad comparator manufactured by onsemi, housed in a 14-pin SOIC package. It operates within a supply voltage range of 3.0 V to 36 V for single supply or ±1.5 V to ±18 V for split supply configurations. The device features an open-collector output capable of sinking up to 16 mA and supports TTL and CMOS logic compatibility. Electrical characteristics include a typical input bias current of 25 nA, a maximum response time of 1.3 µs, and an operating temperature range from -40°C to +105°C.
Feature Summary
- Supports both single and split power supply operations with wide voltage ranges.
- Features low input bias current and low output saturation voltage for high sensitivity.
- Includes ESD protection clamps on inputs to enhance reliability without affecting operation.
- Outputs are compatible with standard TTL and CMOS logic families.
Applications
- Level detection circuits
- Low-level sensing applications
- Memory interface designs
Procurement Notes
Verify the specific suffix 'DR2G' corresponds to the SOIC-14 tape and reel packaging configuration as defined in the manufacturer's ordering information. Confirm that the component meets RoHS compliance standards and lead-free requirements before integration into final assemblies. Ensure design parameters align with the specified electrical limits provided in the official datasheet.
Selection Notes
Select this component when designing systems requiring multiple independent comparators within a compact surface-mount footprint. Consider its wide common-mode input voltage range extending to ground potential. Evaluate the open-collector output structure against load requirements to ensure proper pull-up resistor selection for the target logic family.
Part Context
This part belongs to the LM2901 series of single-supply quad comparators produced by onsemi. It shares functional similarities with other devices in the LM339/LM239 family but is optimized for broader supply voltage ranges. The DR2G designation indicates a specific manufacturing lot and packaging format distinct from through-hole or tube variants.
