Overview
The ALD2301CSAL is a dual precision CMOS voltage comparator from Advanced Linear Devices, housed in an 8-pin Small Outline Plastic Dip (SOIC) package. It operates on single (+5V) or dual (±5V) power supplies within a 3V to 10V range. Key electrical parameters include a typical supply current of 110µA, input bias current of 10pA, and response time of 300ns for TTL inputs. The device features open-drain outputs capable of sinking up to 60mA and supports wired-OR connections.
Feature Summary
- High input impedance with extremely low input bias currents
- Open-drain output configuration supporting wired-OR connections
- Compatible with CMOS, NMOS, and TTL logic families
- Low power dissipation suitable for battery-operated instruments
Applications
- High source impedance voltage comparison circuits
- Dual limit window comparators
- Power supply voltage monitors
- Photo-detector sensor circuits
- Relay or LED drivers
Procurement Notes
Verify the specific suffix 'SAL' corresponds to the lead-free 8-pin SOIC package variant. Confirm that the 'C' grade meets the required offset voltage and temperature specifications for your application environment. Ensure compatibility with standard surface-mount assembly processes for SOIC packages.
Selection Notes
Select this component when high input impedance and low standby power are critical requirements. The open-drain outputs provide flexibility for interfacing with various logic levels. Consider the 'C' grade performance characteristics against stricter tolerance needs found in 'A' or 'B' grades if higher precision is necessary.
Part Context
This part belongs to the ALD2301 family of dual precision CMOS voltage comparators. Variants include A, B, C, and ungraded versions, available in SOIC, PDIP, and CERDIP packages. The ALD2301 serves as a functional equivalent to industry-standard LM193 comparators while offering improved CMOS input characteristics.
Replacement Considerations
The datasheet identifies the ALD2301 as a functional equivalent to the LM193 industry standard comparator.
