Overview
The ALD2332BSAL is a dual precision CMOS voltage comparator with push-pull drivers, manufactured by Advanced Linear Devices. It operates on a single +4V to +10V or dual ±2V to ±5V supply. Key electrical parameters include a typical input bias current of 10pA, a response time of 400ns for a 100mV step, and a high output sinking current of 50mA. The device features an input impedance of 10^12Ω and a gain of 100V/mV.
Feature Summary
- Integrated push-pull output drivers capable of sourcing and sinking current without external pull-up resistors.
- Ultra-low input bias current typically at 10pA, minimizing source impedance effects.
- CMOS, NMOS, and TTL compatible logic levels for broad interface flexibility.
- High-speed response suitable for both large signal transitions and small overdrive signals.
Applications
- MOSFET driver circuits
- Multiple limit window comparators
- Power supply voltage monitors
- Photo-detector sensor circuits
- Oscillators
Procurement Notes
Verify the specific suffix 'SAL' corresponds to the SOIC-8 package variant when ordering. Confirm that the 'B' designation aligns with the required offset voltage specifications for the target application. Ensure lead-free compliance matches project requirements as indicated by the datasheet revision.
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 additional buffer stages or pull-up components. Consider the low power dissipation per channel for battery-operated systems where standby current is critical.
Part Context
This part belongs to the ALD2332 family of dual precision voltage comparators. It utilizes advanced silicon gate EPAD CMOS technology. The device is designed to replace industry standard pinout comparators while offering superior input impedance and integrated output buffering capabilities.
Replacement Considerations
Pin-compatible with LM193 type industry standard voltage comparators. Verify functional equivalence regarding output drive strength and input offset characteristics before substitution.
FAQ
Can the outputs be used in a wired-OR configuration?
Yes, the outputs can be used in a wired-OR connection without a pull-up resistor or tied together with other open-drain circuits.
What is the maximum supply voltage allowed?
The absolute maximum supply voltage rating is +10.6V.
