What this quad op-amp brings to the BOM
The Texas Instruments OPA4310IDR is a quad CMOS operational amplifier that runs on a single 5.5-V supply and delivers 3-MHz gain-bandwidth product with 150-mA output current per channel. That output drive — 150 mA — is the headline number: it lets this part source or sink enough current to drive headphone loads, small relays, or actuator coils without a separate buffer stage. The rail-to-rail output swing keeps the signal clean at the supply rails, which matters in single-supply designs where headroom is tight. It carries ROHS3 compliance and is listed as Active in the lifecycle — no end-of-life watch for new designs.
The OPA4310IDR's 150-mA rating per channel drives loads that typical quad op-amps cannot.
The package is surface-mount; the exact pinout follows the standard quad op-amp footprint (four amplifiers, dual in-line pin arrangement). No special thermal pad or exposed die attach — standard reflow profile applies. Verify the landing pattern against the datasheet when laying out the PCB.
