ALD2301CPAL

Overview

The ALD2301CPAL is a dual precision CMOS voltage comparator manufactured by Advanced Linear Devices, Inc. It features an open-drain output driver and operates on single (+5V) or dual (±5V) power supplies within a 3V to 10V range. The device offers a typical response time of 300ns for TTL inputs and maintains low supply current of 110µA. It provides high output sinking current capability of up to 60mA and extremely low input bias currents typically at 10pA. Packaged in an 8-pin SOIC format, it supports an operating temperature range from 0°C to +70°C.

Feature Summary

• Features open-drain outputs allowing wired-OR connections and flexibility to connect to external voltages higher than V+.
• Provides high-speed performance with a typical 300ns response time for TTL-level input steps.
• Maintains extremely low input bias currents to virtually eliminate source impedance effects.
• Delivers high output sinking current capability suitable for driving loads directly.

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 configuration required for your assembly process. Confirm that the component meets the 0°C to +70°C operating temperature range specifications for your intended environment. Ensure compatibility with standard 8-pin footprint dimensions during PCB layout verification.

Selection Notes

Select this component when low standby power consumption is critical alongside high output drive capability. It serves as a functional equivalent to LM193 industry standard comparators. Consider its CMOS technology benefits for applications requiring high input impedance and compatibility with TTL, NMOS, and CMOS logic families.

Part Context

This part belongs to the ALD2301 family of dual precision voltage comparators built with advanced silicon gate CMOS technology. The family includes variants such as ALD2301A, ALD2301B, and ALD2301C, differentiated primarily by offset voltage specifications. The ALD2301CPAL specifically denotes the C-grade version housed in a plastic DIP package.

Replacement Considerations

The datasheet identifies the ALD2301 series as a functional equivalent to the LM193 industry standard comparator. Verify pinout compatibility and electrical parameter margins before substituting with other dual precision comparators.
