Overview
The ADCMP354YKSZ-REEL7 is a comparator and reference circuit featuring an internal 0.6 V noninverting threshold. It operates on a supply voltage range of 2.25 V to 5.5 V with a typical supply current of 10 µA. The device provides an open-drain digital output capable of tolerating up to 22 V on both the input and output pins. It exhibits a propagation delay of 5 µs, 15 mV hysteresis, and functions within a temperature range of −40°C to +125°C.
Feature Summary
- Features high voltage tolerance on input and output pins for robust operation in harsh environments.
- Integrates a fixed 0.6 V noninverting reference voltage for simplified threshold detection.
- Delivers low power consumption suitable for battery-powered portable equipment.
- Provides an open-drain output stage compatible with various logic families.
Applications
- Voltage detectors
- Microprocessor systems
- Battery monitors
Procurement Notes
Verify the specific ordering suffix REEL7 confirms tape-and-reel packaging when sourcing. Confirm RoHS compliance status via manufacturer documentation. Ensure the SC-70 package dimensions match the target PCB footprint. Validate that the open-drain output configuration aligns with the system pull-up requirements.
Selection Notes
Select this component for applications requiring a fixed 0.6 V threshold with high voltage tolerance. The open-drain output necessitates an external pull-up resistor. Consider the 5 µs propagation delay against system timing constraints. Verify that the 22 V input/output rating exceeds the maximum expected signal levels.
Part Context
This part belongs to the ADCMP35x family from Analog Devices, which includes the ADCMP350 and ADCMP356 variants. These devices share similar electrical characteristics but differ in output stage configuration and input polarity. The ADCMP354 specifically offers a noninverting input with an open-drain output.
Replacement Considerations
The ADCMP350YKSZ-REEL7 serves as a functional substitute if an inverting configuration is acceptable. The ADCMP356YKSZ-REEL7 is an alternative if a push-pull output is required instead of open-drain. All three parts share the same package and core specifications.
