Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix E1-A against the manufacturer's latest datasheet to confirm pinout compatibility and RoHS status. Ensure the TSSOP-14 footprint matches the design layout. Confirm availability through authorized distributors as stock levels vary. Check for any recent obsolescence notices or lifecycle changes directly from Renesas before finalizing procurement plans.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad amplifier with low offset voltage and wide supply range is required. Compare input bias current specifications against other quad op-amps if leakage currents are critical. Verify that the TSSOP-14 package dimensions fit the PCB constraints. Consider the 125°C maximum operating temperature for high-thermal environments.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the UPC451 series of quad operational amplifiers from Renesas. The series includes variants like the UPC451G2-E1-A and UPC451GR-9LG-A, which share similar core architectures but may differ in packaging, voltage ratings, or specific electrical parameters.
