UPC319G2-E1-A

Overview

The UPC319G2-E1-A is a precision analog comparator manufactured by Renesas Electronics Corporation, housed in a 14-SOP surface-mount package. It features two independent channels with open collector outputs, supporting a supply voltage range from 5 V to 32 V. The device exhibits a typical response time of 80 ns at ±15 V and operates with a maximum input offset voltage of 2 mV. It draws 8 mA of operating current and functions within a temperature range of -20°C to +80°C.

Feature Summary

• Precision comparison capability with low input offset voltage for accurate signal detection
• Open collector output configuration providing flexibility in logic interfacing
• Single-supply operation compatible with standard 5 V systems

Applications

• High-speed data acquisition systems requiring precise threshold detection
• Industrial control circuits utilizing TTL-compatible logic interfaces
• Voltage monitoring applications within single-supply power architectures

Procurement Notes

Verify the specific suffix E1-A against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the 14-SOP footprint matches the target PCB design. Confirm that the open collector output requirements align with the downstream circuit pull-up configurations. Validate that the operating temperature range meets the environmental constraints of the final assembly.

Selection Notes

Select this component when high-speed response is critical alongside precision voltage comparison. The open collector output necessitates external pull-up resistors, which must be accounted for in the system design. Consider the 80 ns propagation delay for timing-sensitive applications. The single-supply capability simplifies power management compared to dual-supply alternatives, making it suitable for cost-effective designs.

Part Context

This part belongs to the UPC319 series of analog comparators designed for general-purpose linear applications. It is distinct from operational amplifiers like the UPC324 or UPC842, as it lacks internal compensation for feedback stability. The SOP-14 package allows for compact integration in dense electronic assemblies while maintaining thermal performance within specified limits.
