ALD2302APAL

Overview

The ALD2302APAL is a dual precision CMOS voltage comparator with push-pull driver, manufactured by Advanced Linear Devices Inc. It operates on a single +5V or dual ±5V supply within a 4V to 10V range. Key electrical parameters include a typical input bias current of 10pA, response time of 180ns for TTL inputs, and high output sinking current of typically 60mA. The device features extremely low power dissipation of 175µA per comparator and operates within an ambient temperature range of 0°C to +70°C.

Feature Summary

• Push-pull outputs capable of sourcing and sinking current without requiring external pull-up resistors
• Extremely low input bias currents typically at 10pA, virtually eliminating source impedance effects
• CMOS, NMOS, and TTL compatible logic levels with guaranteed drive for 200Ω loads

Applications

• PCMCIA instruments
• MOSFET driver circuits
• High source impedance voltage comparison circuits
• Multiple limit window comparators
• Power supply voltage monitors

Procurement Notes

Verify the specific suffix 'PAL' corresponds to the 8-pin Plastic DIP package when ordering. Confirm RoHS compliance status as standard versions are lead-free. Ensure the design accommodates the specified operating temperature range of 0°C to +70°C. Check for availability of quad packages like the ALD4302A if more channels are required in the system design.

Selection Notes

Select this component for applications requiring low standby power and high output current flexibility. The push-pull architecture simplifies circuit design by removing the need for pull-up resistors. Consider the ALD2302A variant if tighter offset voltage specifications are needed compared to the standard ALD2302. Ensure the load requirements do not exceed the 60mA sinking capability.

Part Context

This part belongs to the ALD2302 series of monolithic precision high-performance dual voltage comparators built with advanced silicon gate CMOS technology. It shares pinout compatibility with industry standard LM193 type comparators. The series includes variants such as the ALD2302ASAL (SOIC) and ALD2302ADA (CERDIP) for different packaging needs.
