ALD2332PAL

Overview

The ALD2332PAL is a dual precision CMOS voltage comparator utilizing EPAD® technology. It features push-pull output drivers capable of sourcing and sinking up to 50mA, eliminating the need for external pull-up resistors. The device operates on single (+4V to +10V) or dual (±1.5V to ±5V) supplies with a typical supply current of 175µA per comparator. Input bias current is typically 10pA, and response time reaches 180ns for TTL-level inputs.

Feature Summary

• Push-pull complementary outputs provide high-current sourcing and sinking without requiring external pull-up components.
• Integrated input pre-amplifier ensures ultra-low offset voltages and currents for high-precision analog applications.
• CMOS, NMOS, and TTL logic compatibility allows direct interfacing with various digital systems.
• Single-supply operation includes ground in the common-mode input voltage range.

Applications

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

Procurement Notes

Verify the specific suffix against the manufacturer's ordering guide to confirm lead-free status and package type. Confirm that the PAL designation corresponds to the 8-pin plastic DIP package. Ensure the required operating temperature range aligns with the standard commercial grade specifications provided in the datasheet.

Selection Notes

Select this component when high output drive capability is required without external buffering. The push-pull architecture simplifies circuit design by removing pull-up resistors. Consider the low power consumption and high input impedance for battery-operated or high-impedance signal detection applications.

Part Context

This part belongs to the ALD2332 family of dual precision voltage comparators. It shares the industry-standard pinout with LM193-type comparators but offers superior performance through advanced silicon gate EPAD® CMOS technology. The family includes variants with different offset voltage grades and open-drain output configurations.

Replacement Considerations

The datasheet specifies an industry-standard pinout compatible with LM193-type voltage comparators. Verify electrical parameters such as supply current and output drive strength before substituting with generic equivalents.

FAQ
