Overview
The LM2901DTBR2G is a single-supply quad comparator manufactured by onsemi, housed in a TSSOP-14 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 a low input bias current of 25 nA (typical) and an input common mode voltage range extending to ground. Electrical characteristics include a typical response time of 1.3 µs, an output sink current capability of 16 mA, and a low output saturation voltage of 130 mV at 4.0 mA. The component supports operation across an ambient temperature range of -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 input offset voltage for precision sensing.
- Includes ESD clamps on inputs to enhance reliability without affecting device operation.
- Outputs are compatible with TTL and CMOS logic families.
Applications
- Level detection circuits
- Low-level sensing applications
- Memory applications
Procurement Notes
Verify the specific suffix DTBR2G corresponds to the TSSOP-14 package and tape & reel shipping configuration. Confirm that the operating temperature range aligns with system requirements, as this variant supports up to +105°C. Ensure compliance with RoHS standards and lead-free packaging specifications required for the target assembly process.
Selection Notes
Select this component when a quad comparator with rail-to-rail input common mode capability is required. The TSSOP-14 package offers a compact footprint suitable for space-constrained designs. Consider the 1.3 µs response time for signal conditioning tasks where moderate speed is sufficient. Verify that the open-collector output interface matches the pull-up resistor requirements of the downstream logic circuitry.
Part Context
This part belongs to the LM2901 family of single-supply quad comparators from onsemi. It shares functional similarities with the LM339 and LM239 series but is optimized for single-supply operation. The device is designed for consumer, automotive, and industrial electronic applications requiring reliable analog-to-digital conversion interfaces.
