THS3491
Overview
The THS3491 current feedback amplifier (CFA) provides a new level of performance for applications requiring the lowest distortion at high output power levels from DC through values greater than 100 MHz at 100-Ω loads. Although specified at a gain of 5 V/V, this current feedback design holds near constant bandwidth and distortion over a wide range of gains.
- Bandwidth: - 900 MHz (VO = 2 VPP, AV = 5 V/V) - 320 MHz (VO = 10 VPP, AV = 5 V/V)
- Slew rate: 8000 V/µs (VO = 20 VPP)
- Input voltage noise: 1.7 nV/√ Hz
- Bipolar supply range: ±7 V to ±16 V
- Single-supply range: 14 V to 32 V
- Output swing: 28 VPP (±16-V supplies, 100-Ω load)
- Linear output current: ±420 mA (typical)
- 16.8-mA trimmed supply current (low temperature coefficient)
- HD2 and HD3: less than -75 dBc (50 MHz, VO = 10 VPP, 100-Ω load)
- Rise and fall time: 1.3 ns (10-V step)
