Overview
The ALD2303ASAL is a dual precision micropower CMOS voltage comparator manufactured by Advanced Linear Devices. It operates on single (+5V) or dual (±5V) supplies within a 3V to 10V range. Key electrical parameters include a typical supply current of 40µA, input bias current of 200pA, and output sinking current up to 60mA. The device features an open-drain wired-OR output configuration and operates within a temperature range of 0°C to +70°C in an 8-pin SOIC package.
Feature Summary
- Extremely low power consumption combined with high precision for micropower applications
- Built-in high input impedance buffer that virtually eliminates source impedance effects
- Integrated output driver capable of sinking up to 60mA without external buffers
Applications
- Sensor detection circuits
- PCMCIA instruments
- MOSFET driver
- High source impedance voltage comparison circuits
- Multiple limit window comparator
Procurement Notes
Verify the specific suffix 'SAL' corresponds to the lead-free version in the 8-pin Small Outline Plastic DIP (SOIC) package. Confirm the operating temperature range matches the 0°C to +70°C specification for this package type. Ensure compatibility with single or dual supply requirements as defined in the datasheet.
Selection Notes
Select this component for applications requiring low standby power alongside high output current capability. It is suitable for low-level signal detection with high source impedance. Verify that the open-drain output configuration meets the system's logic level translation needs. Consider thermal effects if large output current transients are expected.
Part Context
This part belongs to the ALD2303A/ALD2303 series of dual precision voltage comparators. It shares pinout compatibility with industry standard LM193 type comparators. The series utilizes advanced silicon gate CMOS technology to achieve high input impedance and low bias currents.
Replacement Considerations
The datasheet notes compatibility with other voltage comparator circuits such as the ALD2301, ALD2302, and ALD4302. Verify pinout alignment with LM193 type comparators if substituting legacy components.
