UPC277G2(20)-E1-A

Overview

The UPC277G2(20)-E1-A is a dual general-purpose analog comparator manufactured by Renesas Electronics Corporation. It features an open-collector output capable of sourcing up to 16mA at 5V. The device operates on a single supply voltage ranging from 2V to 32V, or dual supplies from ±1V to ±16V. Key electrical specifications include a maximum input offset voltage of 5mV at 5V and a maximum input bias current of 0.25µA at 5V. The static supply current is limited to a maximum of 1mA. It is housed in an 8-SOP surface-mount package with a width of 4.40mm and supports an operating temperature range of -40°C to 85°C.

Feature Summary

• Dual-channel configuration for independent signal comparison within a compact footprint
• Open-collector output stage allows flexible interfacing with various logic families
• Low input bias current ensures minimal loading effects on high-impedance source circuits

Applications

• General-purpose voltage level detection in industrial control systems
• Threshold sensing applications requiring low power consumption
• Signal conditioning stages in analog-to-digital conversion interfaces

Procurement Notes

Verify component authenticity through authorized distributors as the part status is listed as obsolete. Confirm RoHS3 compliance and check for specific packaging variants such as tape and reel or cut tape. Ensure the 8-SOP package dimensions match the design constraints before finalizing procurement orders.

Selection Notes

Select this component when a dual comparator with low input bias current is required. The wide supply voltage range accommodates both single and dual rail systems. Verify that the open-collector output type aligns with the downstream circuit requirements, as pull-up resistors may be necessary for proper logic level translation.

Part Context

This device belongs to the UPC277G2 series of analog comparators from Renesas Electronics. It is designed for standard general-purpose applications where moderate speed and low power are prioritized. The series offers multiple pinout variations, with the (20) suffix indicating a specific pin configuration compatible with standard SOP-8 footprints.

Replacement Considerations

UPC277G2(20)-E2-AX is listed as a parameter-equivalent substitute by the manufacturer.
