Overview
The ALD2303PAL is a dual precision micropower CMOS voltage comparator in an 8-pin PDIP package. It operates on single (+5V) or dual (-5V) supplies within a 3V to 10V range. Key electrical characteristics include a typical supply current of 40µA, input bias current of 200pA, and output sink current up to 60mA. The device features open-drain wired-OR outputs, a response time of 6.5µs, and operates from 0°C to +70°C.
Feature Summary
- Extremely low power consumption combined with high precision for micropower applications
- Built-in high input impedance buffer virtually eliminates source impedance effects
- Open-drain wired-OR outputs capable of driving loads up to 60mA sink current
Applications
- Sensor detection circuits
- MOSFET driver
- High source impedance voltage comparison circuits

- Photodetector sensor circuit
Procurement Notes
Verify the specific ordering suffix 'PAL' corresponds to the 8-pin Plastic DIP (PDIP) package configuration. Confirm that the component meets RoHS compliance requirements if applicable to the project specifications. Ensure the operating temperature range aligns with the standard commercial grade limits 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 inputs. Consider the open-drain output topology when designing pull-up resistor networks for interfacing with TTL, NMOS, or CMOS logic levels.
Part Context
This part belongs to the ALD2303A/ALD2303 series of dual precision micro-power CMOS voltage comparators. It shares pinout compatibility with industry-standard LM193 type comparators. The device utilizes advanced silicon gate CMOS technology to achieve very high input impedance and low power dissipation per comparator channel.
Replacement Considerations
The datasheet notes pinout compatibility with LM193 type industry standard comparators. Verify functional equivalence regarding supply voltage ranges and output drive capabilities before substitution.
