UPC842GR(73)-9LG-E1-A

Instrumentation, Op Amps, Buffer Amps Overview

The UPC842GR(73)-9LG-E1-A is a dual operational amplifier manufactured by Renesas Electronics Corporation. It belongs to the μPC842 series, designed as a high-speed version of general-purpose amplifiers like the μPC1251 and μPC358. The device features a wide single supply voltage range of 3V to 32V and supports dual supplies up to ±16V. Key electrical characteristics include a typical slew rate of 8.5V/µs, a gain-bandwidth product of 3.5MHz at 100kHz, and an input offset voltage maximum of 4.5mV. It operates within a temperature range of -40°C to +125°C and utilizes an SOP-8 package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• High-speed pulse response with improved slew rate and gain-bandwidth product compared to standard general-purpose amplifiers.
• Stable operation with capacitive loads up to 1000pF due to built-in phase correction circuits.
• Integrated output short-circuit protection for enhanced reliability.
• Pin-compatible with standard dual operational amplifiers for easy design integration.

Instrumentation, Op Amps, Buffer Amps Applications

• Single-supply AC amplifiers
• Active filters
• Line drivers
• Photodetector signal amplification

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via official documentation. Check for obsolescence notices or lifecycle changes. Ensure storage conditions meet specified humidity and temperature limits to prevent damage. Validate package markings against datasheet specifications upon receipt.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high-speed performance and stability under capacitive loads are required in single-supply applications. Consider the extended temperature range (-40°C to +125°C) for industrial environments. Compare against the μPC4742 if a lower commercial temperature range suffices. Ensure the 32V maximum supply voltage aligns with system power rails. Verify pin compatibility with existing designs referencing standard dual op-amp footprints.

Instrumentation, Op Amps, Buffer Amps Part Context

This part is part of the μPC842 family, which includes quad versions like the μPC844. It serves as a high-speed alternative to legacy bipolar op-amps, offering superior transient response without crossover distortion. The GR suffix indicates a specific tape-and-reel packaging variant suitable for automated assembly processes.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The μPC4742G2 offers similar functionality but with a restricted operating temperature range of -20°C to +80°C. Designers requiring wider thermal tolerance should retain the μPC842 variant. Direct pin-for-pin substitution is possible provided thermal constraints are met.
