Overview
The ALD2301BSAL is a dual precision CMOS voltage comparator manufactured by Advanced Linear Devices, housed in an 8-pin SOIC package. It operates on a single supply of 3V to 10V or dual supplies of ±5V. Key electrical parameters include a typical input bias current of 10pA, a response time of 300ns for TTL-level inputs, and a high output sinking current capability of 60mA. The device features open-drain outputs and supports an operating temperature range from 0°C to +70°C.
Feature Summary
- Features extremely low input bias currents typically at 10pA to virtually eliminate source impedance effects.
- Provides high-speed performance with a typical response time of 300ns for TTL inputs.
- Offers flexible wired-OR open-drain outputs capable of sinking up to 60mA.
- Compatible with CMOS, NMOS, and TTL logic families.
Applications
- High source impedance voltage comparison circuits
- Dual limit window comparators
- Power supply voltage monitors
- Photo-detector sensor circuits
Procurement Notes
Verify the specific suffix 'SAL' corresponds to the lead-free 8-pin Small Outline Plastic DIP (SOIC) package variant. Confirm that the B-grade specification meets the required offset voltage and gain tolerances for the target application. Ensure the operating environment remains within the 0°C to +70°C range specified for this package type.
Selection Notes
Select this component when low standby power consumption combined with high output drive capability is required. The ALD2301BSAL is suitable for applications needing precise detection of low-level signals without significant loading effects. Consider the 60mA sink current for direct driving of loads like LEDs or relays where intermediate buffering is undesirable.
Part Context
This part belongs to the ALD2301 series of dual precision voltage comparators built with advanced silicon gate CMOS technology. The series includes variants such as ALD2301A, ALD2301C, and ALD2301, differentiated primarily by input offset voltage specifications. The ALD2301BSAL specifically denotes the B-grade version packaged in SOIC-8.
Replacement Considerations
The datasheet identifies the device as a functional equivalent to the LM193 industry standard comparator. Verify pinout compatibility and electrical parameter margins before substituting with other dual precision comparators.
FAQ
What is the maximum output sinking current?
The ALD2301BSAL provides a high output sinking current of typically 60mA.
Can the outputs be connected to a voltage higher than V+?
Yes, the open-drain configuration allows the outputs to be connected to a higher external voltage than the positive supply rail.
