ALD2301BPAL

Overview

The ALD2301BPAL is a dual precision CMOS voltage comparator manufactured by Advanced Linear Devices, Inc. It features open-drain output drivers and operates on single (+5V) or dual (±5V) power supplies. The device offers low supply current of 110µA typical, fast response time of 300ns for TTL inputs, and extremely low input bias currents typically at 10pA. It provides high output sinking current capability up to 60mA and includes built-in high input impedance buffers. The component is housed in an 8-pin Plastic DIP package.

Feature Summary

• Features open-drain outputs allowing wired-OR connections and connection to external voltages higher than V+.
• Provides high output sinking current capability with built-in output driver.
• Includes built-in high input impedance buffer to virtually eliminate source impedance effects.
• Operates with low supply current spikes and supports both single and dual supply configurations.

Applications

• High source impedance voltage comparison circuits
• Dual limit window comparator
• Power supply voltage monitor
• Photo-detector sensor circuit
• Battery operated instruments

Procurement Notes

Verify the specific suffix 'PAL' corresponds to the 8-pin Plastic DIP package variant when sourcing. Confirm lead-free status as indicated by the ordering information documentation. Ensure compatibility with the required operating temperature range of 0°C to +70°C for this specific package type. Cross-reference pinout configuration against schematic requirements before integration.

Selection Notes

Select this component for applications requiring low standby power combined with high output current drive capabilities. It serves as a functional equivalent to LM193 industry standard comparators. Consider its CMOS, NMOS, and TTL compatibility for mixed-signal environments. Evaluate the 300ns response time suitability for the target signal frequencies.

Part Context

This part belongs to the ALD2301 family of dual precision voltage comparators from Advanced Linear Devices. The family includes variants such as ALD2301A, ALD2301B, ALD2301C, and ALD2301, available in SOIC, PDIP, and CERDIP packages. The BPAL designation specifically identifies the B-grade version in the plastic DIP format.

Replacement Considerations

The datasheet lists the LM193 as a functional equivalent industry standard comparator. Verify pinout and electrical parameter alignment before substitution. No other specific substitute part numbers are confirmed in the provided documentation.
