Overview
The AS331KTR-G1 is a single precision voltage comparator manufactured by Diodes Incorporated, designed for operation from a single power supply over a wide voltage range. It features a typical input offset voltage of 1.0mV and high voltage gain. The device operates with a single supply voltage between 2V and 36V, or dual supplies from ±1V to ±18V. It provides an open collector output and maintains low power-supply current drain independent of the supply voltage magnitude.
Feature Summary
- Wide supply voltage range supporting both single and split power configurations
- Low input bias current and low input offset voltage for precision applications
- Open collector output configuration with low saturation voltage
- Input common mode voltage range includes ground potential
Applications
- Battery chargers
- Cordless telephones
- Switching power supplies
- DC-DC modules
- PC motherboards
Procurement Notes
Verify that the component matches the specific ordering suffix KTR-G1, which indicates tape and reel packaging in the SOT25 package. Confirm compliance with RoHS 3 and lead-free requirements as specified in the datasheet notes. Ensure the operating temperature range aligns with the -40°C to +85°C specification provided for this part number.
Selection Notes
Select this component when a single-channel comparator with low offset voltage and wide supply range is required. The open collector output necessitates an external pull-up resistor. Consider the response time characteristics relative to the load capacitance and input overdrive voltage for high-speed signal processing applications.
Part Context
This part belongs to the AS331 series of low power, low offset voltage single comparators. It is distinct from other Diodes Incorporated products such as operational amplifiers or quad comparators due to its specific single-channel architecture and optimized performance for general-purpose comparison tasks within the specified voltage limits.
