Overview
The UPC277G2(21)-E1-A is a dual-channel general-purpose analog comparator manufactured by Renesas Electronics. 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 16mA. Key electrical specifications include a maximum input offset voltage of 5mV at 5V and a maximum input bias current of 0.25µA at 5V. Static current consumption is limited to a maximum of 1mA. The component is housed in an 8-SOP surface-mount package and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Dual-channel configuration for simultaneous signal comparison
- Open-collector output structure supporting flexible interfacing
- Low input offset voltage ensuring accurate threshold detection
- Wide single or dual power supply compatibility
Applications
- General-purpose voltage level sensing circuits
- Threshold detection systems requiring precise switching
- Signal conditioning stages in analog processing chains
Procurement Notes
Verify the specific suffix designation, as the (21) variant may indicate distinct binning or testing criteria compared to standard versions. Confirm RoHS3 compliance status through official documentation prior to integration. Ensure the 8-SOP footprint matches the target PCB layout constraints. Validate that the open-collector output requirements align with the downstream circuit pull-up configurations.
Selection Notes
Select this component when a dual-channel solution is required with low input bias characteristics. The wide supply voltage range accommodates various system architectures without additional level shifting. Consider the open-collector output topology if wired-OR logic or varying load voltages are necessary. Verify thermal performance within the specified -40°C to +85°C industrial range for the intended environment.
Part Context
This part belongs to the UPC277G2 series of linear IC comparators from Renesas Electronics. It is designed for cost-sensitive applications requiring reliable analog comparison functions. The series typically offers robust performance in consumer and industrial electronics where space efficiency and low power consumption are prioritized alongside functional accuracy.
Replacement Considerations
The UPC277G2(20)-E1-A is documented as a parameter-equivalent substitute. Verify pinout compatibility and electrical specification alignment before substitution. Other family members may require schematic adjustments due to differing output structures or pin configurations.
