Overview
The UPC277MP-KAA-E1-A is a dual general-purpose comparator manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 2V to 32V (single) or ±1V to ±16V (dual). The device features an open-collector output capable of sourcing up to 16mA at 5V. Key electrical specifications include a maximum input offset voltage of 2.5mV and a typical response time of 1.8µs. It functions across a temperature range of -40°C to 85°C and utilizes an 8-TSSOP surface-mount package.
Feature Summary
- Dual-channel architecture for simultaneous signal comparison
- Open-collector output configuration supporting TTL logic levels
- Low input offset voltage ensuring accurate threshold detection
- Wide single-supply operating voltage capability
Applications
- General-purpose analog signal comparison circuits
- Voltage monitoring systems requiring precise threshold detection
- Interface circuits between analog sensors and digital logic
- Over-voltage and under-voltage protection schemes
Procurement Notes
Verify the specific suffix KAA against the official Renesas datasheet to confirm the 8-TSSOP package variant. Ensure compatibility with required logic levels, as the open-collector output necessitates external pull-up resistors. Confirm RoHS compliance status and check for any recent Product Change Notices regarding labeling or manufacturing site updates before finalizing procurement orders.
Selection Notes
Select this component when a dual comparator with low offset voltage and wide supply range is required in a compact TSSOP package. Consider the open-collector output topology, which requires external pull-up components to define high logic states. Evaluate the 1.8µs response time against system speed requirements to ensure adequate performance for the intended application frequency.
Part Context
This part belongs to the UPC277MP series of dual comparators designed for single-supply operation. It shares functional similarities with other members like the UPC277GR but differs in packaging and specific electrical characteristics. The series is engineered for cost-effective signal processing in consumer and industrial electronics where space constraints and power efficiency are critical design factors.
Replacement Considerations
Publicly confirmed substitute part numbers for this specific model were not identified in the provided documentation. Verify pinout compatibility and electrical parameters if considering alternative dual comparators from other manufacturers.
