Overview
The ALD4302SBL is a quad precision CMOS voltage comparator featuring push-pull drivers. It operates on single (+5V to +10V) or dual (±2.5V to ±5V) supplies with a supply current of 600µA to 1000µA. Key electrical parameters include a typical input bias current of 10pA, high gain of 100V/mV, and response times of 120ns for TTL inputs and 400ns for 5mV overdrive. The device supports an output sinking current of up to 60mA and functions within a temperature range of 0°C to +70°C.
Feature Summary
- Features extremely low input bias currents typically at 10pA, virtually eliminating source impedance effects.
- Provides push-pull outputs capable of sourcing and sinking significant current without external buffers.
- Operates with low supply current consumption of 150 µA per comparator.
- CMOS, NMOS, and TTL compatible with rail-to-rail input capability including ground.
Applications
- MOSFET driver circuits
- High speed LED driver applications
- Battery operated instruments
- Multiple relay drivers
Procurement Notes
Verify the specific suffix 'SBL' corresponds to the 14-pin Small Outline Plastic Dip (SOIC) package when ordering. Confirm that the component meets the required operating temperature range of 0°C to +70°C for your specific application environment. Ensure compatibility with standard surface mount assembly processes for SOIC-14 packages.
Selection Notes
Select this component for designs requiring high input impedance and low standby power while maintaining robust output drive capabilities. It is suitable for precision voltage comparison tasks where low offset voltage and high gain are critical. Consider the thermal implications of driving heavy loads due to the high output sinking current capability.
Part Context
This part belongs to the ALD4302A/ALD4302 family of monolithic quad voltage comparators built with advanced silicon gate CMOS technology. The series offers flexibility through various package options including SOIC, CERDIP, and PDIP, catering to different manufacturing and environmental requirements.
Replacement Considerations
The datasheet notes compatibility with wired-OR connections using open drain circuits such as the ALD2301 and ALD2303 voltage comparators. No direct substitute part numbers are provided in the documentation.
FAQ
Can the outputs be used in a wired-OR configuration?
Yes, the outputs can be used in either wired-OR connection without a pull-up resistor or in a push-pull configuration.
What is the maximum output sinking current?
Each output provides a high output sinking current of typically 60mA.
