THS3491 - 500-mA High-Power Output Current Feedback Amplifier

Description

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.

Features

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.
