Overview
The LTC1443CN#PBF is an ultralow power quad comparator with a built-in reference, manufactured by Analog Devices Inc. It operates from a single 2V to 11V supply or a dual ±1V to ±5.5V supply. The device features less than 8.5µA supply current over temperature and includes an internal 1.182V ±1% reference for the LTC1443. Outputs are TTL/CMOS compatible, capable of sourcing up to 40mA continuously. Propagation delay is typically 12µs with 10mV overdrive. It is housed in a 16-lead PDIP package.
Feature Summary
- Ultralow quiescent current consumption
- Built-in voltage reference output
- TTL/CMOS compatible outputs
- Wide supply voltage range
Applications
- Battery-powered system monitoring
- Threshold detectors
- Window comparators
- Oscillator circuits
Procurement Notes
Verify the specific ordering suffix CN#PBF corresponds to the commercial temperature range (0°C to 70°C) and 16-lead PDIP package configuration. Confirm lead-free finish compliance and ensure the component matches the manufacturer's official datasheet specifications before integration into production designs.
Selection Notes
Select this component when low power consumption is critical alongside the need for multiple comparator channels. The integrated reference simplifies circuit design by eliminating external reference components. Ensure the application requires TTL/CMOS outputs and operates within the specified single or dual supply voltage ranges.
Part Context
This part belongs to the LTC1443/LTC1444/LTC1445 family of ultralow power quad comparators. While variants differ in reference voltage accuracy and hysteresis capabilities, the LTC1443 specifically provides a fixed 1.182V reference and standard CMOS outputs without programmable hysteresis features found in other family members.
Replacement Considerations
Pin-compatible upgrades include the MAX924. Other related parts in the Ultralow Power Comparator family may offer different reference voltages or hysteresis options but require verification of electrical characteristics and pinout compatibility.
