290 MHz bandwidth in a dual-channel SOIC-8
The OPA2830ID is a dual voltage-feedback amplifier from Texas Instruments with a 290 MHz -3 dB bandwidth and a 560 V/µs slew rate, packaged in an 8-SOIC. The rail-to-rail output stage lets the signal swing to within millivolts of the supply rails, preserving dynamic range in low-voltage systems. Two amplifiers in one SOIC-8 footprint means a single device handles a differential receive path or a dual-channel filter stage, cutting per-channel board area roughly in half versus two single op-amps.
Supply range and power budget for mixed-voltage boards
Operates from a 2.8 V to 11 V supply span, so it runs on a 3.3 V or 5 V rail without a separate regulator and still has headroom for a 5 V ADC front-end. Each channel draws 8.5 mA quiescent current — 17 mA total for the pair — keeping the thermal rise in the SOIC-8 package manageable at 85 °C ambient. The 82 mA output current per channel drives 50-ohm terminated lines or multiple ADC inputs directly, eliminating a buffer stage in many signal-chain layouts.
