Overview
The ALD2302SAL is a dual precision CMOS voltage comparator in an SOIC-8 package. It operates on a single +5V or dual ±5V supply (4V to 10V range). Key electrical parameters include a typical input bias current of 10pA, response time of 180ns for TTL inputs and 400ns for 20mV overdrive, and high output sinking current of typically 60mA. Supply current is 175µA per comparator. Input offset voltage ranges from 0.5mV to 4.8mV depending on the variant and temperature.
Feature Summary
- Push-pull outputs capable of sourcing and sinking current without requiring external pull-up resistors
- Extremely low input bias currents typically at 10pA to minimize source impedance effects
- CMOS, NMOS, and TTL compatible logic levels with fanout of 30LS TTL loads
Applications
- PCMCIA instruments
- MOSFET driver circuits
- High source impedance voltage comparison circuits
- Multiple limit window comparators
- Power supply voltage monitors
Procurement Notes
Verify the specific suffix 'SAL' corresponds to the 8-pin Small Outline Plastic DIP Package (SOIC) configuration. Confirm RoHS compliance status as standard versions may differ from leaded or high-temperature variants. Check factory documentation for availability of non-RoHS options if required by design specifications.
Selection Notes
Select this component for applications requiring low standby power and high output drive capability. The push-pull architecture eliminates the need for second power supplies or pull-up resistors. Ensure the operating temperature range of 0°C to +70°C meets environmental requirements. Consider the ALD4302A/ALD4302 for quad package needs.
Part Context
Part of the ALD2302A/ALD2302 monolithic precision high-performance dual voltage comparator series built with advanced silicon gate CMOS technology. Designed to provide high gain and fast response times for low-level signal detection circuits.
Replacement Considerations
Pinout matches LM193 type industry standard comparators. Can be used in wired-OR connections with open drain circuits such as the ALD2301/ALD2303 voltage comparators.
