Overview
The UPC277MP-KAA-E2-A is a dual general-purpose linear comparator manufactured by Renesas Electronics. It operates within a supply voltage range of 2V to 32V (single) or ±1V to ±16V (dual). Key electrical specifications include a typical input offset voltage of ±2mV and a maximum input bias current of 0.25µA at 5V. The device features an open-collector output capable of sourcing up to 16mA. It is housed in an 8-TSSOP package with a width of 2.80mm and supports an operating temperature range from -40°C to 125°C.
Feature Summary
- Dual comparator architecture designed for single power supply operation
- Open-collector output configuration enabling wired OR logic connections
- Low input bias current characteristic for high-impedance signal interfacing
Applications
- General-purpose analog signal comparison circuits
- Voltage level detection systems
- Threshold monitoring applications
Procurement Notes
Verify the specific suffix E2-A against official Renesas documentation to confirm pinout compatibility and RoHS status. Confirm availability through authorized distributors as standard stock levels fluctuate. Ensure the 8-TSSOP package dimensions match the target PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when dual comparators are required in a compact TSSOP package. It is suitable for designs needing low input bias current and open-collector outputs. Consider the ±2mV typical offset voltage for precision requirements. Verify that the 16mA output drive capability meets the load requirements of the downstream circuitry.
Part Context
This part belongs to the UPC277 series of dual comparators from Renesas Electronics. The series includes variants such as UPC277GR and UPC277MP, which share similar functional characteristics but may differ in package types like SOP or MSOP. These components are widely used in industrial and consumer electronics for basic analog comparison tasks.
Replacement Considerations
The UPC277G2(20)-E1-A is listed as a substitute by distributors. Verify pin-to-pin compatibility and electrical parameter alignment with the original datasheet before substitution.
