Overview
The ALD2321SCL is a dual precision CMOS analog voltage comparator in a 16-pin SOIC package. It operates on a single supply of 4V to 10V or dual supplies of ±2V to ±5V, with a typical supply current of 110µA. The device features an ultra-low input offset voltage of up to 0.5mV and input bias currents as low as 0.01pA. Each comparator provides separate push-pull outputs capable of sinking up to 50mA and sourcing up to 2mA. Response time is typically 1.1µs for a 5mV input step.
Feature Summary
- Ultra-low signal power detection capability down to 4fW
- Integrated e-trim technology for minimal offset voltage
- Dual complementary output drivers for flexible configuration
- High-speed response with small overdrive voltages
Applications
- Dual limit window comparator circuits
- Power supply voltage monitoring systems
- Photo-detector sensor signal processing
- Relay or LED driver interfaces
- Battery operated instruments
Procurement Notes
Verify the specific suffix 'SCL' indicates the lead-free version within the 16-pin Small Outline Plastic DIP (SOIC) package. Confirm that the operating temperature range aligns with your design requirements, specifically the 0°C to +70°C limit for this package type. Ensure the ordering information matches the manufacturer's current revision standards.
Selection Notes
Select this component when high-precision comparison of low-level signals from high-impedance sources is required. The integrated complementary outputs eliminate the need for external buffer stages. Consider the 16-pin SOIC form factor for surface-mount assembly constraints. Verify that the 50mA sink current meets load driving needs without additional amplification.
Part Context
This part belongs to the ALD2321 family of ultra-low Vos EPAD dual CMOS analog voltage comparators. It shares architectural similarities with the ALD2321A and ALD2321B variants, differing primarily in factory trimming specifications for offset voltage. The SCL designation identifies the specific package and lead-free compliance status within the Advanced Linear Devices portfolio.

FAQ
How are the VE pins utilized in standard operation?
The VE pins are used for factory electronic trimming of the offset voltage and should normally be left open unconnected. They can alternatively serve as feedback pins to provide hysteresis.
What is the maximum sink current capability?
The sink output pin can handle a current sink capability of up to 50mA.
