THS7530/THS7530-Q1 Variable Gain Amplifier
Texas Instruments THS7530/THS7530-Q1 Variable Gain Amplifier is fabricated using TI's state-of-the-art BiCom III SiGe complementary bipolar process. The THS7530/THS7530-Q1 is a DC-coupled, wide bandwidth amplifier with voltage-controlled gain. The amplifier has high impedance 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 300MHz bandwidth, and third harmonic distortion of -61dBc at 32MHz with 1VPP output into 400Ω. Gain control is linear in dB with 0V to 0.9V, varying the gain from 11.6dB to 46.5dB with 38.8dB/V gain slope. Output voltage limiting is provided to limit the output voltage swing and to prevent saturating the following stages. The THS7530-Q1 devices are AEC-Q100 qualified for automotive applications.
