Overview
The ALD2301SAL is a dual precision CMOS voltage comparator in an 8-pin SOIC package. It operates on single (+5V) or dual (±5V) supplies within a 3V to 10V range. Key electrical parameters include a typical response time of 300ns, supply current of 110µA, and input bias current of 10pA. The device features open-drain outputs capable of sinking up to 60mA.
Feature Summary
- High-speed operation with 300ns response time for TTL inputs
- Extremely low input bias currents typically at 10pA
- Open-drain outputs allowing wired-OR connections
- CMOS, NMOS, and TTL compatible logic levels
Applications
- High source impedance voltage comparison circuits
- Dual limit window comparators
- Power supply voltage monitors
- Photo-detector sensor circuits
- Battery operated instruments
Procurement Notes
Verify the specific suffix 'SAL' corresponds to the lead-free 8-pin Small Outline Plastic DIP (SOIC) package variant. Confirm the operating temperature range matches the 0°C to +70°C specification for this package type. Ensure compatibility with the required supply voltage and load conditions before integration.
Selection Notes
Select this component for applications requiring high input impedance and low standby power. The open-drain output configuration provides flexibility for interfacing with higher external voltages. Consider the 300ns response time for signal detection requirements and verify that the 60mA sink current meets the load drive needs.
Part Context
This part belongs to the ALD2301 family of monolithic dual voltage comparators built with advanced silicon gate CMOS technology. The family includes variants such as ALD2301A, B, C, and standard versions, differentiated by offset voltage specifications and temperature ranges. The SAL suffix denotes the surface-mount SOIC package option.
Replacement Considerations
The datasheet identifies the ALD2301 series as a functional equivalent to the LM193 industry standard comparator. Verify pinout compatibility and electrical parameter alignment when substituting.
