Signal-chain fit: voltage feedback topology and dynamic range
The THS4031ID is a single-circuit voltage feedback amplifier from Texas Instruments, built for applications where a 100 MHz -3dB bandwidth and a 100V/µs slew rate set the dynamic ceiling — think high-speed ADC drivers, video distribution, or pulse amplification where the output must swing fast without slewing into distortion. A 9 V to 32 V supply span means it runs on common ±5 V, ±12 V, or ±15 V rails with enough headroom for a 20 Vpp output swing into a 100-Ω load without clipping into the supply limits.
Package and thermal: 8-SOIC footprint for dense boards
Housed in the industry-standard 8-SOIC package (0.154″ body width, 3.90 mm), the THS4031ID's surface-mount footprint matches the SOIC-8 land pattern used across thousands of op-amp designs — no board respin needed if swapping from a different single-channel voltage-feedback amp in the same package. The tube delivery is typical for prototype or low-volume assembly; for reel quantities, confirm the packing option with your distributor at RFQ time.
Supply current and input offset: power budget and DC accuracy
Quiescent supply current is 8.5 mA per amplifier — moderate for a 100 MHz device, meaning the thermal rise in still air stays low enough that no heatsinking is needed in most signal-chain layouts. Input offset voltage is 500 µV maximum; input bias current is 3 µA. For a non-inverting gain-of-2 stage with 1-kΩ feedback resistors, the offset error from bias current is about 3 mV at the output — negligible for a 2 Vpp signal but worth budgeting in a precision DC-coupled path.
Temperature grade and compliance
Rated for -40°C to +85°C ambient, the THS4031ID suits industrial control cabinets, base-station transceivers, and test equipment that sees temperature swings outside the commercial 0-70°C band.
