The THS7530 device is a DC-coupled, wide bandwidth amplifier with voltage-controlled gain. The amplifier has highimpedance differential inputs and low-impedance differential outputs with high-bandwidth gain control, output common-mode control, and output voltage clamping. Signal-channel performance is exceptional with 300-MHz bandwidth, and third harmonic distortion of – 61 dBc at 32 MHz with 1-VPP output into 400 Ω. Gain control is linear in dB with 0 V to 0.9 V varying the gain from 11.6 dB to 46.5 dB with 38.8-dB/V gain slope. Output voltage limiting is provided to limit the o...
