They come in the compact WSON-8-EP (8-lead with exposed thermal pad) surface-mount package, making them suitable for space-constrained PCB designs requiring ultra-wide bandwidth performance.\u003c\/p\u003e\n\u003ch4\u003eQ: Why is a 5.5 GHz gain-bandwidth product important for my circuit?\u003c\/h4\u003e\n\u003cp\u003eA: A 5.5 GHz gain-bandwidth product (GBP) means the amplifier can maintain stable, useful gain well into the gigahertz range. This is critical for high-speed photodiode receivers, LIDAR front-ends, and optical sensing applications where signal frequencies are very high and traditional op-amps would fall short.\u003c\/p\u003e\n\u003ch4\u003eQ: What does \"de-compensated\" mean for the OPA858?\u003c\/h4\u003e\n\u003cp\u003eA: \"De-compensated\" means the amplifier is not internally compensated for unity-gain stability. It requires a minimum closed-loop gain (typically set by external feedback components) to remain stable. In exchange, it delivers significantly better bandwidth and slew rate at higher gain settings compared to fully compensated amplifiers — ideal for transimpedance amplifier (TIA) designs.\u003c\/p\u003e\n\u003ch4\u003eQ: How many ICs are included in this listing?\u003c\/h4\u003e\n\u003cp\u003eA: This listing includes a pack of \u003cstrong\u003e5 pieces\u003c\/strong\u003e of the OPA858IDSGR \/ OPA858IDSGT, giving you spares for prototyping, production runs, or replacements.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What is the OPA858IDSGR \/ OPA858IDSGT and what package does it come in?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The OPA858IDSGR and OPA858IDSGT are high-speed, de-compensated transresistance (transimpedance) amplifiers featuring a FET input stage.
