What the 800 MHz bandwidth and 240 V/µs slew rate mean on a real board
The OPA820ID is a single-channel voltage feedback amplifier with a -3dB bandwidth of 800 MHz and a slew rate of 240 V/µs — fast enough to handle high-speed signal chains like ADC front-ends, video distribution, or pulse amplification where the edge rate matters more than the flat gain bandwidth. Drawing 5.6 mA supply current, it sits between a general-purpose op-amp and a full-current-feedback part on the power budget — the 110 mA output drive per channel means it can swing into a 50-ohm load or drive a long cable without an external buffer.
Supply rails and temperature grade — where it fits in the system
Runs on a supply span from 5 V to 12 V, single or split — the 5 V minimum means it works off a standard 5 V rail without a boost converter, and the 12 V ceiling covers most ±5 V or ±6 V split-rail applications. Rated for -40°C to 85°C ambient, so it handles industrial control cabinets and outdoor telecom enclosures that see seasonal temperature swings — not quite full military, but fine for most factory-floor and base-station gear.
Package and board integration — 8-SOIC footprint
Housed in the standard 8-SOIC (0.154-inch body width, 3.90 mm), supplier device package 8-SOIC — the same footprint as an LM358 or OPA2134, so it drops into existing PCB layouts without a board spin if the pinout matches. Surface-mount only — no through-hole option. The 1.27 mm pitch is easy to hand-solder with a fine iron, but the narrow body means the feedback and supply traces need to fan out cleanly to keep parasitic capacitance off the inverting input.
