120 MHz GBW and 115 V/µs slew rate — the bandwidth ceiling for the feedback network
The OPA625IDBVT is a single-channel general-purpose operational amplifier from Texas Instruments with a 120 MHz gain-bandwidth product and a 115 V/µs slew rate. The GBW sets the small-signal bandwidth ceiling for whatever feedback network you close around it — at a noise gain of 10, expect roughly 12 MHz closed-loop bandwidth before the open-loop gain rolls off. The 115 V/µs slew rate determines the large-signal full-power bandwidth into the load capacitance; driving a 10 pF load at 2 Vpp, the output rise time is about 17 ns, which keeps the signal distortion low up to several megahertz. The rail-to-rail output stage lets it swing within millivolts of either supply rail, so it can drive an ADC input full-scale without a separate level-shift stage. Supply range is 2.7 V to 5.5 V single supply, drawing 2 mA quiescent current — the power budget fits a 5 V system with margin for the load current.
Active lifecycle and RoHS3 compliance — no supply-risk flags
The part is ROHS3 compliant, which means no exemption-driven material restrictions that could create supply constraints. The operating temperature range is -40°C to 125°C, covering industrial and automotive ambient qualification. The SOT-23-6 package is a compact 6-lead footprint — the PCB layout engineer should verify the thermal pad connection if dissipating more than a few hundred milliwatts, as the junction-to-ambient thermal resistance for this package is around 200°C/W without a copper plane.
Sourcing and availability — quoted to order
The OPA625IDBVT is sourced through authorized and independent distribution channels. The part is supplied in Tape & Reel (TR) or Cut Tape (CT) options — the reel quantity is typically 3000 pieces per reel for the SOT-23-6 package, which matters for the pick-and-place setup cost at the CM.
