ALD2301PAL

Overview

The ALD2301PAL is a dual precision CMOS voltage comparator manufactured by Advanced Linear Devices, housed in an 8-pin Plastic DIP package. It operates on a single supply of 3V to 10V or dual supplies of ±5V. Key electrical parameters include a typical response time of 300ns for TTL-level inputs and 650ns for low-level signals, with a maximum power dissipation of 600mW. The device features open-drain outputs capable of sinking up to 60mA and supports wired-OR connections.

Feature Summary

• Features extremely low input bias currents typically at 10pA, virtually eliminating source impedance effects.
• Provides high output sinking current capability of up to 60mA with open-drain configuration.
• Supports wired-OR connections and allows outputs to connect to external voltages higher than V+.

Applications

• High source impedance voltage comparison circuits
• Dual limit window comparators
• Power supply voltage monitors
• Photo-detector sensor circuits

Procurement Notes

Verify the specific suffix 'PAL' corresponds to the 8-pin Plastic DIP package and commercial temperature range (0°C to +70°C). Confirm lead-free status if required, as indicated by the 'L' suffix convention in the ordering information. Ensure compatibility with existing PCB footprints for through-hole mounting.

Selection Notes

Select this component when low standby power consumption combined with high output drive capability is required. It serves as a functional equivalent to LM193 industry standard comparators. Consider the open-drain output structure for applications requiring level shifting or multiple outputs connected together.

Part Context

This part belongs to the ALD2301 family, which includes variants A, B, C, and standard versions differentiated by offset voltage specifications. The PAL suffix specifically denotes the plastic DIP packaging option within the broader series that also offers SOIC and CERDIP packages.

Replacement Considerations

The datasheet identifies the ALD2301 as a functional equivalent to the LM193 industry standard comparator. Verify pinout and electrical characteristics match before substitution.
