ALD2332BPAL

Overview

The ALD2332BPAL is a dual precision voltage comparator manufactured by Advanced Linear Devices Inc. It utilizes EPAD® CMOS technology and features push-pull output drivers. The device operates on a single supply of +4V to +10V or a dual supply of ±2V to ±5V. Key electrical parameters include a maximum input bias current of 20pA, a typical response time of 400ns with a 100mV input step, and a high output sinking current of 50mA. It offers a common mode rejection ratio of 80dB and power supply rejection ratio of 75dB. The component is housed in an 8-PDIP package and supports an operating temperature range of 0°C to +70°C.

Feature Summary

• Integrated push-pull output driver capable of sourcing and sinking current without external pull-up resistors.
• Ultra-low input bias current typically at 10pA, minimizing source impedance effects for high-impedance signal detection.
• CMOS, NMOS, and TTL compatible logic levels with high gain of 100V/mV.
• Single-supply operation includes ground in the input voltage range.

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 the specific suffix 'PAL' corresponds to the 8-pin Plastic DIP (PDIP) package variant when ordering. Confirm RoHS compliance status as the datasheet indicates the 'L' suffix denotes lead-free versions. Ensure the required operating temperature range aligns with the commercial grade specification of 0°C to +70°C. Cross-reference pinout compatibility with industry standard LM193 type pinouts if replacing existing designs.

Selection Notes

Select this component for applications requiring high output drive capability directly from the comparator stage. The push-pull architecture eliminates the need for external pull-up resistors found in open-drain designs. Consider the low supply current of 175µA per comparator for battery-operated instruments. Verify that the 50mA sink current meets load requirements without necessitating additional buffer stages.

Part Context

This part belongs to the ALD2332 family of dual precision voltage comparators. It shares the same core architecture as the ALD2332A and ALD2332B variants, differing primarily in performance specifications such as offset voltage and bandwidth. The ALD2332 series is designed for high-precision analog applications using advanced silicon gate EPAD® CMOS technology.

Replacement Considerations

The datasheet specifies a pinout compatible with the LM193 type industry standard voltage comparators. Designers should verify functional equivalence regarding output drive strength and input offset characteristics before substituting other brands.
