ALD2301APAL

Overview

The ALD2301APAL is a dual precision 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 parameters include a typical supply current of 110µA, input bias current of 10pA, and response time of 300ns for TTL inputs. The device features open-drain outputs capable of sinking up to 60mA.

Feature Summary

• High input impedance with extremely low bias currents to minimize source impedance effects
• Open-drain output configuration supporting wired-OR connections and external voltage levels
• CMOS, NMOS, and TTL compatible logic interfaces

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 'PAL' corresponds to the 8-pin Plastic DIP package and commercial temperature range (0°C to +70°C). Confirm RoHS compliance status as the datasheet indicates 'L' suffix for lead-free versions. Ensure the ordering code matches the required performance grade (A, B, C, or standard) for offset voltage specifications.

Selection Notes

Select this component for applications requiring low standby power combined with high output current capability. The wide common-mode input voltage range including ground makes it suitable for low-level signal detection. Consider the functional equivalence to LM193 if migrating from legacy designs.

Part Context

This part belongs to the ALD2301 family of monolithic dual precision voltage comparators built with advanced silicon gate CMOS technology. The family includes variants like ALD2301ASAL and ALD2301ADA, differing primarily in packaging and operating temperature ranges while maintaining identical pinouts and core electrical characteristics.

Replacement Considerations

The datasheet identifies the ALD2301 series as a functional equivalent to the industry-standard LM193 comparator.
