These figures mean it can amplify signals up to nearly 2 GHz before the gain drops by 3 dB — suitable for RF intermediate stages, high-speed ADC drivers, or wideband transimpedance amplifiers where preserving signal amplitude across frequency matters. Its 1150 V/µs slew rate ensures the output can track fast input transitions without slew-rate limiting, which would otherwise introduce nonlinear distortion on pulse edges or high-frequency sine waves. For a 1 V peak-to-peak output at 1.8 GHz, the required slew rate is roughly 11.3 V/µs — this part has over 100× margin, so slew-induced distortion is not a concern across the full bandwidth. ## Package and thermal: 8-WSON with exposed pad Housed in an 8-WFDFN exposed-pad package (supplier device package 8-WSON, 2 mm × 2 mm), the OPA859IDSGR is a surface-mount part with a thermal pad underneath. The exposed pad must be soldered to a PCB ground plane with thermal vias to achieve the datasheet thermal resistance — without this, the junction temperature rises above the -40°C to 125°C operating range under high output current or ambient heat. The 105 mA output current per channel means the part can drive 50-ohm loads to about 5.25 V swing — useful for driving transmission lines or high-speed ADC inputs directly. The 20.5 mA supply current is moderate for this speed class; the 3.3 V to 5.25 V supply span lets it run from a single 3.3 V or 5 V rail common in mixed-signal systems. ## Active lifecycle and sourcing posture The automotive-grade sibling OPA859QDSGRQ1 shares the same bandwidth and slew rate but adds AEC-Q100 qualification for -40°C to 125°C operation. If the end application requires automotive PPAP or reliability screening, the Q-grade variant is the drop-in replacement — same package, same pinout, same electrical performance.","metaTitle":"TI OPA859IDSGR Op Amp, 1.8 GHz, 1150 V/µs, 8-WSON","metaDescription":"Texas Instruments OPA859IDSGR general-purpose op amp: 1.8 GHz -3 dB bandwidth, 1150 V/µs slew rate, differential output, 8-WSON package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Memory (DRAM / SRAM / Flash / EEPROM)"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Slew Rate":"1150V/µs","Output Type":"Differential","Mounting Type":"Surface Mount","-3db Bandwidth":"1.8 GHz","Amplifier Type":"General Purpose","Package / Case":"8-WFDFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Supply":"20.5mA","Number of Circuits":"1","Operating Temperature":"-40°C ~ 125°C","Gain Bandwidth Product":"900 MHz","Voltage - Input Offset":"900 µV","Supplier Device Package":"8-WSON (2x2)","Current - Output / Channel":"105 mA","Voltage - Supply Span (Max)":"5.25 V","Voltage - Supply Span (Min)":"3.3 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.92","priceTiers":[{"qty":1,"price":"$4.92000","currency":"USD"},{"qty":10,"price":"$4.41700","currency":"USD"},{"qty":25,"price":"$4.17600","currency":"USD"},{"qty":100,"price":"$3.61930","currency":"USD"},{"qty":250,"price":"$3.43372","currency":"USD"},{"qty":500,"price":"$3.08106","currency":"USD"},{"qty":1000,"price":"$2.62650","currency":"USD"},{"qty":3000,"price":"$2.62650","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/3bb893b5545b76fb88ca1e28b47dd1d6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/OPA859IDSGR/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source for OPA859IDSGR?","answer":"The OPA859QDSGRQ1 is the automotive-grade variant (AEC-Q100 qualified) with identical 1.8 GHz bandwidth, 1150 V/µs slew rate, and 8-WSON package.
