The THS3491IDDAR from Texas Instruments is a 900-MHz high-power output current-feedback amplifier designed for demanding applications. It features a wide bandwidth of 900 MHz at 5 V/V gain and a rapid slew rate of 8000 V/µs, enabling fast signal transitions.
This amplifier operates with a total supply voltage ranging from 14 V to 32 V. It provides a significant output current capability of up to ±420 mA typical and an output swing of 28 VPP with a 100-Ω load. The input voltage noise is low at 1.7 nV/√Hz.
Available in VQFN, HSOIC, and DIE packages, the THS3491IDDAR is suitable for surface mount applications. It includes features such as current limit and thermal shutdown protection, as well as a power-down mode for power efficiency. The operating temperature range is -40°C to 85°C.
Key electrical characteristics include a typical quiescent current per channel of 17.1 mA and a maximum offset voltage of 2 mV at 25°C. Harmonic distortion is kept low, with 2nd and 3rd harmonic distortion below -75 dBc at 50 MHz.
The THS3491IDDAR can operate from a single supply of 14 V to 32 V or from dual supplies of ±7 V to ±16 V.
The THS3491IDDAR is available in VQFN, HSOIC, and die (DIE) packages.
The operating temperature range is -40°C to 85°C.
The bandwidth is 900 MHz (typical) at 2 VPP output and gain of 5 V/V.
The slew rate is 8000 V/µs (typical) for a 20 VPP output step.
The input voltage noise is 1.7 nV/√Hz (typical) at flatband and 3 nV/√Hz at 1 kHz.
The amplifier includes current limit and thermal shutdown protection, and a power down feature.
