OPA4990IRUCR

Instrumentation, Op Amps, Buffer Amps Overview

The OPA4990IRUCR is a quad operational amplifier from the OPAx990 family, featuring rail-to-rail input and output capabilities. It operates on a supply voltage range of 2.7 V to 40 V with a quiescent current of 120 µA per amplifier. Key electrical parameters include a gain-bandwidth product of 1.1 MHz, a slew rate of 4.5 V/µs, and an input offset voltage of ±300 µV. The device provides high common-mode rejection of 115 dB and low noise density of 30 nV/√Hz at 1 kHz.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'IRUCR' against the manufacturer's datasheet to confirm the package type (X2QFN) and tape-and-reel packaging configuration. Ensure the ordering code matches the required industrial temperature range and pinout specifications for your design.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a quad amplifier with high-voltage support up to 40 V is required. It is suitable for applications needing rail-to-rail signal handling and low power dissipation. Consider the X2QFN package size constraints and thermal management requirements during PCB layout.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OPAx990 series, which includes single (OPA990), dual (OPA2990), and quad (OPA4990) variants. The family shares identical electrical characteristics but differs in channel count and package options. The OPA4990IRUCR specifically utilizes the 14-pin X2QFN package.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct replacements within the same family include OPA4990IDWR or OPA4990IPWR, provided the TSSOP or SOIC packages are acceptable alternatives to the X2QFN form factor.
