High-speed voltage feedback amplifier in 8-SOIC
The THS4041CD is a single-channel voltage feedback amplifier from Texas Instruments, specified for a -3dB bandwidth of 165 MHz and a slew rate of 400 V/µs. It draws 8 mA of supply current and can deliver 100 mA per channel, making it suited for driving capacitive loads or transmission lines in high-speed signal chains. The amplifier operates from a dual supply span of 9 V to 32 V, covering common ±5 V to ±15 V rails used in test equipment and communications infrastructure.
Parametric fit for high-speed signal conditioning
With a 165 MHz bandwidth and 400 V/µs slew rate, this amplifier supports large-signal pulse fidelity up to several tens of megahertz — the slew rate limits the full-power bandwidth before the small-signal bandwidth does. Input offset voltage is 2.5 mV typical and input bias current is 2.5 µA typical — these DC errors are manageable in AC-coupled paths but should be budgeted in DC-restoration or precision integrator circuits. The 0°C to 70°C commercial temperature grade fits indoor bench instrumentation, rack-mount test gear, and office-environment equipment — not extended industrial or automotive ambient.
Package, compliance, and sourcing posture
Housed in an 8-SOIC package (0.154-inch body width, 3.90 mm), the THS4041CD is supplied in tubes and uses standard surface-mount assembly — no exotic footprint or thermal pad beyond the SOIC-8 land pattern. Sourced through authorized and independent distribution channels; availability and current pricing confirmed at RFQ against your BOM quantity.
