The OPA859IDSGT: Its 1.8 GHz -3dB bandwidth and 900 MHz gain-bandwidth product place it in the class of parts used for photodiode transimpedance amplifiers, ADC input drivers, and high-speed data acquisition front-ends. The 1150 V/µs slew rate means it can track large-swing pulses — think 2 Vpp at several hundred megahertz — without slewing into distortion. Supply range runs from 3.3 V up to 5.25 V, so it fits into common single-rail systems. The output is differential, which pairs naturally with differential-input ADCs or long cable drives. The 8-WSON (2x2) package with exposed pad keeps the thermal path short for the 21 mA quiescent current plus 105 mA output drive.
The OPA859IDSGT operates from a minimum supply of 3.3 V up to a maximum of 5.25 V, covering the two most common single-supply rails in portable and industrial designs.
ROHS3 compliance is confirmed, which simplifies the compliance declaration for EU-market builds.
