ALD2332APAL

Overview

The ALD2332APAL is a dual precision CMOS voltage comparator with push-pull output drivers, manufactured by Advanced Linear Devices. It utilizes silicon gate EPAD® CMOS technology and operates on single (+5V) or dual (±5V) power supplies within a 4V to 10V range. The device features an input impedance of 10^12 Ω, low input bias current of 10pA, and response times ranging from 180ns for TTL inputs to 400ns for 20mV overdrive. It provides high output sinking current of 50mA and operates in the 0°C to +70°C temperature range.

Feature Summary

• Push-pull complementary outputs capable of sourcing and sinking current without external pull-up resistors
• Integrated input pre-amplifier providing ultra-low offset voltages and currents for high-precision analog applications
• CMOS, NMOS, and TTL compatible logic levels with industry-standard pinout compatibility

Applications

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

Procurement Notes

Verify that the specific part number suffix 'PAL' corresponds to the 8-pin Plastic DIP package configuration as documented in the manufacturer's ordering information. Confirm that the component meets lead-free specifications if required by your assembly process, noting that alternative leaded versions may be available upon direct factory inquiry.

Selection Notes

Select this component when application requirements demand both high-speed signal detection and significant load driving capability. The integrated push-pull stage eliminates the need for external buffer components, simplifying circuit design. Ensure the operating environment remains within the specified commercial temperature range and that the supply voltage aligns with the 4V to 10V operational limits.

Part Context

This device belongs to the ALD2332 family of monolithic dual precision voltage comparators. It shares architectural similarities with other models in the series but distinguishes itself through its push-pull output topology, contrasting with open-drain variants like the ALD2331. The component is designed for high-precision analog tasks requiring low standby power and robust output drive characteristics.

Replacement Considerations

The datasheet specifies pinout compatibility with LM193 type industry standard voltage comparators. Verify electrical parameters such as response time and output current capabilities against existing designs before substitution.
